Deconstruction of CvS2

Classic Fighting Games Capcom VS SNK 2

Like the the MvC2 deconstruction thread, but working on CvS2.
[Mvc2 Thread](Deconstructing the MvC2 Dreamcast CD

Quick run down of the files.

Don’t expect me to update as often as the MvC2 thread. As I’ll only work on it as a little break from MvC2.

Files on the DC version
1ST_READ - Main programming
ADX - The standard music file even used to this day

MESE_ - English Text messages.
MESJ_ - Japanese Text messages

STG##POL Polygon files for the stages.
STG##TEX Texture files for the stages.

EDIT_P## Color Edit graphic

Player Files
PL##_FAC - Probably the hud portraits.
PL##PAK - Graphic file pixel art and palettes
PL##_HIT - most likely hitboxes
PL##_TBL - probably attack damage,life,jump arcs, etc
SND_PL## - Player Sound Files

Now some actual content.
PL##PAK File Start File Pointers



GRAPHIC1 GRAPHIC2 PALETTES 00000000
00000000 00000000 00000000 00000000

That is the setup for the pak files.

Graphic 1 is usually a pointer to 0x00000020
Graphic 2 the pointer is always different due to the different size and sprite work of a character.
Palettes points directly to the start of palette table LP color.

Hex edited cvs2 coming soon? Very cool stuff, thanks for digging around in these games for us!

4

so whats the goal/purpose? run it on pc or something?

5

I doubt I’ll go as far as far porting it. Maybe a viewer/editor for it.

6

is that really complicated? even if you had help from super professionals like say…damdai and/or someone like that? I always wondered if there was a way to run cvs2 on a pc without emulation. just straight up mugen style but leave the game unchanged lol…

7

^-- No, you would have to reimplement the entire game.

8

I’ve only seen it done once not officially.

Viewer/editor would be awesome!
