Yeah, I think you’re right.
Well textures would be simple to port.
As for CVS1 to CVS2 All I get is a TV in the middle.
Wow, that looks like some psychadelic shit.
Only thing I can find in the memory is the textures on cvs1.
Here is loading STG00POL and STG00TEX from Cvs1 to Cvs2
Hmm… 
That’s a shame then.
Thanks for trying!
It’ll take some work but it is doable.
Edit
Welp DC files are the menu.
Do you mean we can’t replace mvc2 stages with mvc1 stages? Because I really was looking for a tutorial in order to do that :(. If it just a matter of “stretching” the stages, could you give me some information about how to do that? a link to a tutorial or a program will be enough. Good job btw, hope you keep improving until making a complete balance patch :).
There is no tutorial and no stage replacements. Just basic edits or files from another capcom game. The only tool is a hex editor.
I lost a lot of steam since I had access to a debugger on older games where I could just trace the cpu to find data way more easily. Instead of looking at pointers to pointers to pointers to pointers then finding some data.
Damn. Then I will look for a Mugen, maybe I can found something there. You know, I asked it because I think mvsc1 stages looked way better than the mvc2 ones, so I thought: why nobody is modding that? I saw some mods but those were just new colors for the characters or music replacements, those are cool btw but the default stages MUST go ;). well, thanks anyway.
I’ll probably start working on it more when Mess gets better Dreamcast emulation or I get a debug unit.
There’s a couple versions of various of the stages (desert, clock, etc), so you could probably start figuring pieces out that way. I think the chief problem is that nobody has any time. :\
First thing in the files are pointers to the static objects. The big problem is trying to figure out where active objects are.
Active objects like the boat and fog in the swamp stage or the Propellers, fog, and other airships in the air ship stages. Or, another example New York from CvS2 the helicopter and Robot are active objects. I have no clue where they are how they’re programmed it how they’re activated etc. There is still a lot more to poke around with just a debugger would make this a lot faster instead of poking around in the memory searching for pointers.
Edit:
Also, another question I could figure out with a debugger. Is how effects are applied to the static object like the texture scroll from the training mode menu.
A friend gave me the idea to back port hitboxes to the earlier games recently.
Results
MvC2 Sent
CvS2 Sagat
The reason why Sagat turned out so well is that the cvs2 characters were hardly changed since their a3 counter parts. Also the push box could be wrong on Sentinel.
But I’m here to explain the Dat file for MvC2 more.
The first 64 bytes are pointers in the file.
40 00 00 00 | 40 7F 06 00 | 40 E4 06 00 | 60 EB 06 00
00 00 00 00 | 60 EB 07 00 | 40 3D 08 00 | 00 46 08 00
00 4E 08 00 | 00 5C 08 00 | C0 5E 08 00 | 40 63 08 00
00 6B 08 00 | 40 77 08 00 | 00 00 00 00 | 00 00 00 00
Gonna use good ol’ Ryu as an example. It might not look like pointers, but they are. Cause as much as capcom loves pointers they love big endian.
So that 0x40000000 is actually just 0x00000040 which is the end of the pointers and the start of another table.
Dunno, what every pointer goes to. The one at 0x1C is the Hitbox table while 0x18 is the hit box choice table.
After a weekend poking around in Skullgirls.
Follow up on the Dat file pointers.
Pointer
0x00 Graphics
0x04 Graphics
0x08 Palette
0x0C Unknown
0x10 Blank
0x14 Animation(Not fully figured out)
0x18 Hitbox Choice Table
0x1C Hitbox Table
0x20 Attack Table (exact start of the attack data usually begins with Standing Light Punch*)
0x24 Unknown(looks like scaling)
0x28 Unknown(looks like scaling)
0x2C Unknown(Starts with 0x90 could be life or meter)
0x30 Unknown
0x34 Unknown(Table is similar to the one 0x30 is pointing at)
0x38 Blank
0x3C Blank
*Look at the attack format posted earlier for more info.
Interesting notes took a look at Charlie’s Hitbox table is the same as the one xmvsf dunno about the choice table though.
Cool!
Pointer 0x14 deals with animation haven’t fully figured it out yet but the frame data is near it.
Hitboxes so far you load a value from the animation table, then multiply it by 16, add that value to hitbox choice table then each 2 bytes after the category value on the choice table is a box if it isn’t 0. You multiply that by 8 and add it to the hitbox table pointer to get which hitbox you use.
Edit:
Example with Spiral’s Standing/Walking Hit boxes. Values are big endian
So we start with this animation cell
00 00 04 00 24 00 00 00 80 00 00 00 00 00 00 00 00
00 00 01 00
0x04 means it lasts for 4 frames and 0x0024 is the animation cell. At the end there that 0x0001 is the hitbox group.
So multiply it by 16 and get 0x10 add that to the choice table pointer (0x0011C400).
00 00 F3 80 01 00 02 00 03 00 00 00 F0 00 00 00
So we have more values remember these values are in big endian.
0000
80F3 Catergory
0001 Box
0002 Box
0003 Box
0000 Box
00F0 Box
0000 Box
So we have 4 boxes 3 hurt I know are hurt (F0 is probably the grab as push box isn’t used for grabs in this game).
times the box values by 8 and add it to the Hit box table pointer (0x0011C9C0).
Endian removed on boxes for easy reading.
Box 0x0001 values
0008 0015 FFA0 000D
X = 8
Width = 15
Y = -96
Height = 13
Box 0x0002 values
0006 001C FFB7 0013
X = 6
Width = 28
Y = -73
Height = 19
Box 0x0003 values
0006 0018 FFE5 001B
X = 6
Width = 18
Y = -27
Height = 27
Box 0x00F0
0000 001F FFD2 002F
X = 0
Width = 31
Y = -46
Height = 47
Wished I had more info today but unfortunately no.
The animation part for each dat file looks like it starts with the same 0x100 bytes(besides the Abyss 3 only 2 bytes different).
Looks like a table that points to another table which is nearby.
fRyu Animation Pointer 0x07EB60
You take the 0x016C add it to the animation pointer. Which will take you 0x07ECCC read from that table another table. Which starts you with 0x0578 then add that to the pointer again to the address to the get first cell of the standing animation.
Then look at my previous post what that nets you.
Random ass strings. In files this time Charlie.
I have a lot of addresses to look at.
Messed by picking one a random and they go to no data or have no effect.
Either these addresses are for the arcade version or they’re removed completely.

Oh, this just gave us some more info on attacks.
Damage Format Update.
I could have this messed up but it’s looking like that it’s still the same as the commented code above.
00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f
DM AB AK DK DZ HS ?? SB ST ST ?? VC ?? SD ?? ??
HM ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ??
DM = Damage
AK = Damage_Type first half/ High, low, unblockable settings second half byte
DK = Hitstun type first half/ Element type second half
DZ = Dizzy/Piyo
HS = Hit Stop
SB = Sand bag How long you lay on the ground. This could actually be sleep time.
ST = Sleep Time?
SD = Sound Effect
HM = Hit Mark
Edit:
I won’t really know what all it does until I can get some one to translate the comments.
