Hacking the ST rom

Serious???

So with this rom and 4 SSF2 TB boards, I could get this running like I have done with the TB boards before, just will have Turbo characters? is there any other bugs apart from the ones already in TB?

What’s wrong with dreamcast? Its the closest official port we have, just have a monitor where you can widen/scale the viewable area… have a vmu plugged. Into the 3rd slot for the dipswitches. And there you go. Pretty much arcade perfect port of everything that matters gameplaywise for cheap. Ok, fine, SOMETIMES you’ll get 1 frame of input lag… but almost no one will notice… and there’s probably a way to get rid of it too… still, its hellof a lot better than ggpo, more consistent than PCs, better than HDR classic mode or CCC. And easier to setup than something like xmame (which, by the way, will sometimes have lag that’s not the normal CPS2 lag)

Also, I have a hankerin feeling that SOMETIMES 1 extra frame of input lag in NKIs video might just be a result of the monitors refresh rates not lining up.

Finally, if you’re doing it for the bonus stages its probably just for shits and giggles and that 1 frame of input lag REALLY doesn’t matter

There is a faux terminal check(it will always pass even not connected to anything) a lot of the glitches are caused by trying to read the other boards(which no emulator supports the linking). It needs to be worked on quite a bit before it can be fully used. The address of FF8349 should of given you the clue that it isn’t a rom hack, yet.

Huh? I was just surprised that the stages were in the Dreamcast version. I could care less about supposed lag or version comparisons when it comes to laying the beatdown on cars and barrels. Chill out with the assumptions.

well, if you make a one word ambiguous post, one HAS to make assumptions…

I took your “serious???” (especially with 4 question marks as “you crazy???”

^ that screen gave me memories lol, I ripped all the hitboxes images on that stage, I took advantage of the purple brackground, which is easier to convert to transparent (since purple is not used anywhere else).

Anyway, guys, sorry for delaying this, but the guide is finally done. Sorry for the bad english, i usually re-read everything i write to fix obvious errors (english is not my native language) but i didnt had time to actually do this with the guide. I may update it in the future though, to fix some errors and add other possible discoveries. A tip which i forgot to mention is: whenever you’re going to alter the geometry of a hitbox, catch the respective from the wiki, and do the math based on it (zoom, and count the pixels, or if you’re using a better tool you can place rectangle or a line and check its size).

EDIT 12/28: updated guide: http://uploaded.net/file/p0o9ahsw

The thing about that post is that there is palettes for 8 more stages.

Edit: One thing I should tell you is that the first 4 megs in the ram is the rom on Mame decrypted you could of used save states instead of actually editing the rom.

I always put this on my notes if I’m working on a cps2 game.

Thanks for that jedpossum, by the way i did a fast update just to include that table and fix an mistake in the image.

You could’ve just asked :). No worries though. As long as the flaming barrels are present on the Dreamcast version, I’m happy.

Thanks for the guide Born2providepeoplewithawesomeSTinformationforfree!

You damn straight! XD It is fully featured with extras (Shin and Tien Gouki with super) and the most fun to the true original Cps2.

oh shit oh shitsomeone look into this ,pleaes.
ifNOTHING ELSE gets check…pleasde please please please l

m,atch vids oin the boss stages is capone like!!!

I’ve never seen the cover art for that before. Pretty boss!

I know this is off topic, but Anak’s much needed buff.

I guess that’s a bad match for Morrigan.

Is that his push box?

Hey, interesting thread. Glad someone was able to make use of my old research.

As for things to fix should we hack ST; It’s a pretty minor thing, but Akuma’s graphics have a lot of errors. Parts clipped off, frames missing, frames playing in the incorrect order, etc.

Been tweaking quite a bit of stuff; it’s a lot of fun, and a great learning experience.

jedpossum, where exactly are the character palettes in the ROMs, and how does one go about editing them? I’m also really curious if it’s feasible to eventually add a few colors to each character permanently under different inputs (like PPP and KKK).

It is feasible to add more palettes especially if you add more Roms which is possible. I dunno where they’re at for ST I haven’t looked for them. But if you’re editing on Mame you can edit the palette ram.

Player 2

The difference of the formats is pretty simple in the ram there is a brightness variable(going to be shown as V) that the actual format on the Rom version lacks. So only edit the last 3 numbers.
