Hi, fellow arcade gamers,

Something has been irking me for a long time now. Back in the day at several spots, I encountered Street Fighter II arcade cabinets (original SF2) that played like the normal game with one key difference: all background elements normally hidden in Ken’s and Chun Li’s stages were displayed. This would be a Taipei street sign and a trash bin in Chun Li’s stage and a set of large chains in Ken’s stage. I’ll add some pictures later if I can track them down. It seemed the only foreground tile maps that survived were the fence on the left and pulley and chain system in Zangief’s stage and Sagat’s palm tree, the second of which they of course removed in Champion Edition on forward.

Now, if you use an emulator like Final Burn that allows you to disable graphics layers, load up whichever original SF2 ROM, and then you get to Ken’s or Chun Li’s stages, next you can disable everything except for these hidden foreground layers (I forget which one… Layer 1 maybe?), you will see the graphics I speak of. You can also go into the test menu with DIP C8 and look through the SCROLL1 objects and you’ll eventually find them, among the familiar gfx and some unused gfx.

However, when I was a kid, I on rare occasions saw at arcades and a CA campground once with the SF2 arcade all these layers present with the extra tile maps on top. I can’t tell you what revisions/hacks these were or if they were bootlegs, nor do I remember if they were the original outer cabs or not, but they were all running the original Street Fighter II game without wildly accentuated special moves with 10,000 fireballs and crack speed typical in the hacks lol. Officially, Capcom masked out Ken’s and Chun Li’s foreground gfx by throwing them in the very back in terms of priority of all present gfx layers; like I said with my Final Burn findings, they truly are always there, yet just underneath all the other layers.

With all that being said, has anyone else ever seen these extra graphics out in the wild too, or am I experiencing the Mandela Effect, like hardcore? 😰

P.S. While I haven’t found a hack that does this yet, I would love to have one that enables these hidden foreground layers. I dunno, I just think they’re cool and add extra detail to the already detailed world of SF2.

i always wanted to enable this , but it's not easy...
Got to the same point as your screenshot but it seems the x + y and priority is wrong.

fixed priority but it's not staying in position / scrolling at the rate needed.

i think this is about as far as it goes playing with the A reg's, probably more is needed.

EDIT: chunli stage added

If this was a common enough ROM version that you bumped into it in the wild I wonder if it's worth just loading up all the MAME versions one by one to find one that has it and then compare to the normal versions to see how they're enabled.

There is no dump of this version.. FWIW, i've never seen a version like that running, only seen snaps similar to what we have generated above.

Good call. I'm not 100% sure if I've tried them all since there's a ton of hacks (especially SF2CE), but I haven't been able to find one with those layers visible 'natively', sadly. That would be cool. Even though it's been many moons since I saw the real ones, I'm 90% sure it was only SF2 that displayed those graphics which dramatically lowers the number of clones to go through and check out. I still checked out most if not all of the SF2CE clones anyway, just out of curiosity. This really makes me wonder if I was actually playing a bootleg running on different hardware. I think there are still some non-working bootlegs in MAME, last time I checked.

If only I had a camera on me back then! Better yet, if I only I knew what I knew now about the real CPS-1 hardware and cajoled the arcade operators to let me look at the boards =]
