The Rumored SuperGrafx Conversion

Of all the Strider home conversions, the one for the NEC SuperGrafx has been the subject of the most debate. Which is odd, because it was never actually released. Lots of theories about why it never saw the light of day have been advanced over the years, but when exposed to the light of day themselves, these theories amount to little more than rumor and urban legend.

That's really all there is to it. If you want hard facts and the final word on what happened to the SGX conversion, you're going to be disappointed. The only people who know anything for sure aren't talking, and without their accounts, all the evidence is inconclusive.

If, on the other hand, you like urban legends and are comfortable with interpreting circumstantial evidence, do I ever have a story for you.

Pull up a chair and get comfortable. This one's going to take a while.

In 1989, Capcom ruled the arcades. Their CPS-1 games (e.g. Forgotten Worlds, Ghouls N' Ghosts, and Strider) were their calling cards and were very nearly licenses to print money. Strider in particular was a huge draw, due to its large, colorful sprites, thrilling gameplay mechanics, and voice samples that made it seem like a playable Saturday morning cartoon. Naturally, Capcom licensed their CPS-1 games to the home consoles of the time, and the Genesis port of Strider heavily contributed to that console's early success.

But all was not well. Nintendo was unhappy because Capcom had made their competitor's more powerful system a success, but that's a story for another time. More importantly, NEC was also unhappy. NEC's PC-Engine/TurboGrafx was struggling to take off in America, due to two things: Nintendo's virtual monopoly on third-party developers, and a large part of NEC's Japanese game library consisting of RPG's. Bringing these games to America would mean translating hundreds, if not thousands, of hours of RPG dialog.

Instead of doing that, NEC developed a new system, the PC-Engine 2/SuperGrafx. Since Capcom was the third-party developer most successful at sticking it to Nintendo, NEC bought licenses to port Capcom's games to their new system, perhaps hoping the same thing would happen to them that happened to Sega.

This is crucial. NEC licensed the Capcom titles and developed them in-house through NEC Avenue. Keep this in mind.

In late 1990, NEC announced its new system and the slate it had lined up for the first, and as it turned out, only generation of SGX games. One of these was, naturally, Strider. NEC made some pretty hefty claims concerning its upcoming port, which the Japanese gaming magazine PC Engine Fan reported in its September issue of that year:


"Strider Hiryu"

Ghouls N' Ghosts proved the graphical capabilities of the SuperGrafx. Undoubtedly, there is nothing left but Strider.

Surprising action

Capcom produced some high-quality entries in the field of action games (Forgotten Worlds, Ghouls N' Ghosts, etc.); they outdid themselves with this masterpiece. The animation of the hero was drastically above that of similar action games up to that time. The PC Engine version will make an appearance only for SG, and the frames of animation should be able to be converted satisfactorily. However, I hope that so many animations are preserved without bogging down the speed of the game.

^ Hiryu's movement is this game's highest selling point.

<- This slope displays its varied gameplay.

The backgrounds cannot be beat, either.

In this game, the beauty of the backgrounds adds charm to the gameplay. The exotic backgrounds have enthusiastic fans even now. If it appears on the SuperGrafx, it is possible to accurately translate these beautiful backgrounds by taking advantage of the characteristics of BG2 -- the second scrolling layer. However, such high quality screens definitely consume a lot of game memory.

-> He fights in these backdrops.

-> He can climb to the tops of towers...

<- And fight on these towers. There is such a variety of action; the hero grabs, climbs, flies, bounds, and flips.

*The screens on this page are from the Arcade version.

Right away, somebody was making promises they couldn't keep, saying the backgrounds could be "accurately translated" (i.e. "arcade perfect"). Let's put this old rumor to bed once and for all, right now. The SGX port would not have been "accurately translated". Nor would it have been "better-than-arcade". Out of the question. It couldn't have been. CPS-1 specs completely trounced SGX specs:

STRIDER ROM: 43 Mb 8-10 Mb (rumored)

The difference between the two games' ROM sizes alone is telling. The CPS-1 ROM weighs in between 32 and 43 megabits. The ROM size for the SGX cartridge was going to be a measly 8 Mb, meaning the game was going to have to take a 75-80% reduction in image quality just to fit on the cartridge!

The claim that the SGX's BG2 scrolling background layer would allow accurate translation is ridiculous. CPS-1 had three scrolling layers. With a reduction in ROM size and a reduction in scrolling layers, the SGX version could not and would not have been arcade perfect. No way. Someone wasn't paying attention when they wrote that article.

Meanwhile, back in the States, someone was paying attention. Unfortunately, that person happened to be working for Electronic Gaming Monthly. In its early days, instead of actually writing their own features, EGM was notorious for stealing everything they could from the Japanese gaming mags.

Someone wrote in to the January 1991 issue of EGM and inquired about Strider for the SGX, having caught wind of the planned port. In answering his questions, EGM claimed they'd actually played the game while on a trip to Japan the previous September. Whether they actually did or not is anybody's guess. It's unlikely that the port was in any kind of playable form, having just been announced. EGM's article included two screenshots purporting to be from the SGX version, one of which would survive for years as the only tangible proof this port was ever in production. Astute readers will note, however, that these two shots were taken from PC Engine Fan #9, and EGM merely repeated what they had said.

Just as EGM was passing along four-month-old news and announcing this port's release, PCE Fan was actually reporting a change in plans:



Are SG games being canceled?

"Strider Hiryu", which was announced as an exclusive title for the SuperGrafx at the time of the SuperGrafx' announcement, has been changed into a PC-Engine/SG bi-compatible format. This is probably good news for PC-Engine users, but will stop SGX users' hearts. With this announcement, the lineup of SGX games developed by NEC Avenue has been ended. But of course, the SuperGrafx will still be supported in a dual-format game, maintaining high-quality play. Incidentally, "Strider Hiryu" is one of the few HuCard games scheduled to have 8 Megabits.

* The screenshot on this page is from the Arcade version of "Strider Hiryu". It has become bi-compatible.



Within four months' time, the announced SGX port was demoted from a full SGX game to merely being "SGX compatible". Basically it was scheduled to be a PCE game that could be played on an SGX, similar to how PSone games can be played on a PS2.

This news also signaled the end of SGX game development. NEC Avenue, as noted before, was the only developer the SGX had. By canceling their line, they effectively killed the console, but they were trying to keep it on life support by releasing dual-format games.

Things did not look good, either for the SGX overall or Strider fans in particular. Nine months passed. Then, in September 1991, a FULL YEAR after the original announcement, PCE Fan ran an update:

PC-Engine/SG bi-compatible format (tentative)

"Strider Hiryu" has many fans due to its stylish action and pacing. The game's charm is the smooth animation of the hero Hiryu. The PC-Engine version will be a full conversion from the arcades, although the characters have become somewhat smaller. Moreover, on the SG, there is less flicker compared with the PC-Engine. The between-stage cutscenes are to be reproduced as-is. Since development is likely to be delayed, the release will probably be pushed to next year.

Development status is at 20%.

^ Hiryu faces a gorilla robot. He's not as tough as he looks!

^ Stylish action with Hiryu atop various mechanisms. That is the charm of this game.

There's several things worth noting here. First, they actually admitted the loss in quality by converting from CPS-1 to SGX ("the characters have become somewhat smaller"). Second, the cutscenes they're talking about are not the ones from the Duo version. They're the ones we all know from the CPS-1 ("Hum, it is Strider Hiryu. He will never leave Eurasia alive."). Third, even at this date, they're saying that the game won't be out anytime soon.

How right they were. The game didn't come out in 1991. It didn't even come out in 1992, and in October of that year, EGM writer "Terry Aki" (a pseudonym if ever there was one) ran a little blurb in his "International Outlook" section, noting that Strider had once again been demoted, this time to a Super CD-ROM. Yet he still claimed it would be "greatly enhanced", once again underscoring just how out of the loop EGM really was.

I can't really blame him. Even PCE Fan didn't know what was going on. For example, they claimed the pictures they ran alongside their SGX articles were culled from the arcade, that is, the original CPS-1 version. But even a cursory glance shows this is not the case. Observe:

The screencap on the left is from the arcade; the one on the right is taken from the Sept. 1990 issue of PC Engine Fan. I'm sure you can tell there's more than a few differences between these two screenshots, just by glancing at them. According to Chris Covell and malducci over at the PCEngineFX forums, here's how those differences break down:

  1. The shot on right is missing the "starfield" background layer (BG3).
  2. The two shots seem to be using entirely different palettes.
  3. These screencaps also have two different resolutions. The resolution of the shot from the article seems to match one of the maximum resolutions of the SGX (352 pixels), while the arcade shot (left) has had to be trimmed down to match.
  4. There's no time elapsed in the shot on the right and its current score tally is 0, despite the player being halfway through the first level.
  5. Falchion's slash animation is different. It's curved more and tapers around Hiryu's body more in the shot on the right than in the left-hand screencap.
  6. Hiryu seems to have the edge of a red sash sticking out from his waist in the shot on the right. No existing Strider conversion has a Hiryu sprite like that.
  7. The health meter is completely red and has a gradient on each segment in the shot on the right. No existing Strider conversion has this.
  8. The pole Hiryu's clinging to in the shot on left is thicker than the one from the screencap on right.

The amazing thing about the images from PCE Fan is not that they're different, but that the differences are CONSISTENT from shot to shot. Anyone can doctor a sprite. EGM's done this in many an April Fool's edition. However, I've never seen a hoax with so many screenshots that didn't mess up. Changing sprites is the obvious way to create a fake. Who would think to alter health meters and zero out high scores and make the same changes to every single shot?

Like I said earlier, someone at PCE Fan wasn't paying attention. They didn't know what they had on their hands. Of course, it's entirely possible that the screencaps are from a beta of the CPS-1 version, but why would PCE Fan run beta screencaps when the arcade down the street had working cabinets?

With even the Japanese gaming magazines getting confused, it's no wonder so many rumors popped up about this conversion. No one could get their story straight because there was no straight story to be had.

Finally, in 1994, Strider made it to the PC-Engine/TGX, in a home conversion for the Arcade Card that failed to capture gamers' interest, despite brand-new cutscenes, a new level, and an arranged soundtrack. NEC Avenue, who produced the conversion, didn't even bother to bring it stateside. That's how little confidence they had in it.

After all the hype, people wondered what happened. Why did the SGX version disappear? What about those beautiful screens seen in EGM? Did that mean someone had a working prototype? No one seemed to have any answers, and the rumor mill started to grind.

The first, and most natural rumor, was that there was a playable version floating around. This stood to reason. If NEC Avenue had actually worked on an SGX conversion, a prototype would exist.

In a 1997 post on the Turbo List, a mailing list for NEC enthusiasts, someone named Mike Lyon claimed that, all in all, NEC made five working prototypes. His post marked the first time anywhere on the Net that anyone claimed a specific number of prototypes existed. What's more, he accounted for each of them:

Subject: SG Strider: The Scoop

Here's the the scoop on Strider for the SG, for all those who are not familiar with the story.

Strider WAS programmed, up to about level 4, for the Supergrafx. It is not vaporware, as is frequently reported. Instead of using a Strider "mold" (looking at previous code and formatting it for the system), the programmers started from scratch, which was a long and costly endevour. The game was intended to surpass even the arcade version, which sounds good to me. The Supergrafx was more than capable of it.

When the project was scrapped, due to the massive NES/PCE war that I will not get into, there were FIVE WORKING E-proms. Not cards. E-proms. That's prototypes for all of you not in the know. They're big, ugly, and look nothing like Hu-cards. I do not wish to discount [some random poster], but just how his friend got a hold of this is f***ing beyond me. Take these factors into account:

Copy #1 went to the Hudson vaults. There it will remain until Hudson goes out of business, at which point it will become part of the Hudson estate or be turned over to a company that might buy them out.

Copy #2 went to the head programmer of Strider. I believe he lives in Kobe. Good luck in finding him.

Copy #3 was given to the original designer of Strider, who had a close interest in the development of the SG version. After the failure of the SG, he wasn't present for the ACD development, which could account for it's poor quality.

Copy #4 was the press copy; this is the copy that Gamefan and EGM and all those mags had the Strider pictures in. The press E-prom contained only the first level of the game and a credit sequence, if I'm correct. The press copy, to the best of my knowledge, no longer exists.

Which leaves copy #5 and copy #5 ALONE unaccounted for. Maybe [previously mentioned poster]'s friend is the lucky guy who owns THIS TRULY ONE OF A KIND ITEM, but I HIGHLY DOUBT IT.

If [previously mentioned poster]'s pal does have the 5th copy, he'd better cough up some Polaroids real quick, or there are going to be many skeptical and angry turbo fans on this list!

Lyon!

All rumors concerning the number of betas or alphas or prototypes for the SGX Strider conversion trace to the above post. Even Daniel Riley of SuperGrafx Extreme and his assertion that there were four copies of a three-level playable alpha in existence trace back to this post. If it's correct, then one EPROM went to Hudson, because they were the first-party developer for the TGX and SGX. They owned a huge share of NEC. Strider's lead programmer was Isuke, so that's where another went; and a third went to either Moto Kikaku or Tatsumi Wada, the "original creator[s] of Strider". The fourth, the press copy, may still be around but is most likely in a landfill. It was complete at least through level two, as the screencaps from PCE Fan prove.

That left one EPROM remaining, according to this post. But is this account trustworthy? Mike Lyon stated that the ROM had been completed through level 4, the Amazon stage. That's about 80% complete. This is curious, because the Sept. 1991 PCE Fan indicated the game only reached 20% completion. It could have been developed further, as another year elapsed between when it was demoted to the bi-compatible format and it being demoted yet again to the Arcade Card. Still, 80% completion seems to be pushing it.

Lyon also says the SGX was "more than capable" of beating the CPS-1. That couldn't possibly happen.

Then he talks about the EPROMs. EPROMs do indeed look nothing like HuCards or CD-ROMs, however, it's possible to dump an EPROM onto a HuCard. That's how the HuCard manufacturing process worked, in fact. If there were five EPROMs around, it's possible, if unlikely, that someone dumped one to a HuCard. Ultimately, Lyon's post (and all subsequent Strider SGX prototype rumors, for that matter) should be taken with a grain of salt. The never-substantiated tale of five EPROMs has taken on mythic proportions and turned into a self-perpetuating myth that continues to this day.

Another slightly more sinister urban legend that persists to this day is the rumor that one of the programmers working on the SGX version committed suicide. The story goes that this unfortunate soul was put under intense pressure to deliver a superior port. As Mike Lyon noted above, the SGX conversion required all-new source code, unlike the MegaDrive/Genesis conversion, which was compatible with the CPS-1. Trying to live up to the hefty promises made on behalf of the SGX conversion caused this young man to crack, and he was committed and eventually killed himself. As an homage to this programmer, when Capcom included Hiryu's cameo on Ken's stage in Street Fighter Alpha 2, they also included a teddy bear. Presumably the teddy bear represented the programmer's regression.

This rumor originally surfaced as a factoid on Videogames.com's article "The History of Street Fighter", where it read as follows:

Street Fighter Trivia

Rumor out of Capcom had it that Strider's inclusion in Ken's background was a tribute to a former Capcom employee who had been involved in working on a conversion of Strider for NEC's ill-fated SuperGrafx console. The story has it that NEC placed heavy pressure on the Strider team to cram more detail into the SuperGrafx conversion than had been fit on the 8-megabit Sega Genesis cartridge, and that the Capcom employee cracked under the stress and wound up in a mental hospital. Strider's SFA2 teddy bear was supposedly a reference to the employee's intractable condition. Strider was cancelled for the SuperGrafx and an unimpressive port was released years later for the PC Engine.

From there, it spread to Ralph's Mysterious Video Game Deaths page, where it took on a new iteration under the heading, "That Guy Who Killed Himself Over Strider":

Although prototypes are rumored to exist, SuperGrafx Strider never saw the light of day. Eventually a port to NEC's PC Engine Arcade Card was released in the mid '90s, but it paled in comparison to even Sega's flawed release. It is this failure to surpass even the Genesis/Megadrive's level of quality that apparently drove one of its programmers to suicide. Although this is a completely unsubstantiated rumor, I have heard from very trustworthy sources that one of the programmers took his own life in a bout of depression allegedly caused by the poor quality of the game.

The suicide rumors started there. Ralph had at least admitted that the story was "completely unsubstantiated rumor", but that didn't prevent the tale from spreading like wildfire.

Not to be insensitive to the programmer's family if this story is true, but I've never believed anyone committed suicide over the SGX version, simply because there's a teddy bear in the CPS-1 game itself. It's a bonus item you can obtain in Level 3, the Flying Battleship Ballog. Here's how to find it: once you've passed the turrets and the railgun in the opening sequence, get to the floor. You have a choice to either go down and crawl along the outside of the battleship, or continue on inside. Behind you should be three levels of platforms, covered in shells. Destroy the shells. Get to the top platform. The teddy bear will pop out of a porthole and laugh at you. How could a teddy bear that's an homage to the programmer's mental breakdown appear in a game that was released before the supposed breakdown occurred?

Now, this doesn't necessarily disprove the programmer's breakdown. It just makes the teddy bear rumor highly suspect.

This programmer was never named, but I used to think it was Isuke. I based my opinion on two pieces of evidence. When insertcredit.com's Chaz Seydoux interviewed Roy Ozaki of Mitchell Corp back in January of 2006, Ozaki had this to say concerning Strider and Isuke in particular:

CHZ: One memorable aspect of Cannon Dancer is its similarity to Capcom's Strider Hiryu. Strider Hiryu and Cannon Dancer had the same game designer, Isuke. Were other ex-people from Capcom working on the game?

OZA: You know that game people move around. We had some Capcom misfits in the past.

My second piece of evidence came from Darran Jones, of Retro Gamer magazine. He loves the Strider series, but his magazine has yet to do an issue about it. When asked why, Darran answered,

Believe it or not, I actually have a contact with Isuke (the guy who created Strider) but he's very reluctant to talk.

Which in a way is probably a good thing, because once I have a making of that bad boy my work on RG will be done and I can embrace new technology again.

Taken together, these two things seemed to imply that Isuke is difficult to work with. If Isuke and the mysterious programmer who had a breakdown are one and the same, it would explain a lot. Isuke was difficult to work with during his tenure at Mitchell Corp because he was recovering from a total breakdown. He would be reluctant to talk about Strider because that would be an embarrassing period of his life. And of course, the fact that Isuke's still very much alive would decisively put an end to the rumor that someone killed themselves during the development of the SGX port.

That is entirely my personal speculation on the matter, however. The actual history may be something else entirely.

Regardless, the SGX port was never released. It did exist at one point in a developmental stage, but whether it still does is something only the archivists at Moto Kikaku, Capcom, or possibly Hudson would know. It may surface one day, but unless that happens it will continue to be consigned to urban legend status.

Don't give up hope in the meantime, though. ;^)

In closing, I'd like to thank Chris Covell and malducci for their stellar research into the PC Engine Fan articles that convinced me they were the real deal; Laurence of NFG Games, for pointing out the flaws in Mike Lyon's Turbo List post and just generally being a good sport; Parallax Scroll of the Retrogaming Roundtable, for sending me the scans of EGM 18's article; and everyone who's cited this page as a source over the years. You all have my gratitude.
