It works ! Except perhaps something missing on the title screen ? (see my screenshot)

To the OP :
- Follow the guide at http://neo-source.com/index.php?topic=2379.0 up to IV
- Copy/paste my code at the end of src/burn/drv/neogeo/d_neogeo.cpp
- Finish the instructions in the guide

I'll take a look at version 9 and 9b later (or you could try adding it yourself if you understood the general process)

Fighterchar:
the process is so hard for me :eek:

Actually i wasn't able to get version 9 to work yet, the rom seems to load fine but the emulator crash, and my debug tools didn't give me any useful information, so i guess there is some kind of protection/encryption ?
I didn't try version 9b.

Fighterchar:
if possible to patch IPS in this roms hacks? I have a rom called kof2k2ps2 but the sound is bad, I need a rom hack whit Orochi Iori, and the Kof2k2omg have a good Orochi Iori the voice is good and de sprites :wink:

If you look in hbmame's source, find the GAME macro, and read the word just before ROT0. If it says "neogeo", then it's unencrypted and should just work.

Then i have no clue why this one would crash :

Perhaps dink or iq_132 could tell me what i'm doing wrong ?
