(edit)
Actually I'm thinking about finding someone, to harmonize my collection, to reprogram the EPROMs for 2 of my games with the original code because I want to use INFINIKEY to keep EPROM "clean" for all the games.
No strange screen, no Phoenix logo, no special menu, just the original game back :)
How can I be sure that the files I'll get will be 100% correct ? Is there a website 100% viable ?

If the roms work with an Infinikey, then more than likely they are the original ones. You have to have some know-how to be able to re-encrypt roms (I couldn't do it).

Anyway, you could just burn the roms yourself. Buy a TL866 programmer and a cheap eprom eraser from eBay. It's like a 70 euro investment. Then download the Mame roms (use Google) and check them against Mame to make sure.

Thank you :)
If you intend to use infinikey to return the board to official state you can just burn the erased EPROMs with XVS 03I and XVS 04I as the original stickers state.
These files are found in the MAME's xmvssfj.zip file.

Capcom own EPROM versioning for the games is the capital letter printed after the ROM socket number.
No letter means the EPROM has the first issue of the data, A is the first revision and so on.

In this particular game only ROMs 03 and 04 were encrypted and needed to be changed to run the board on suicided state.

Just look inside the MAME ROMs that aren't marked as bootlegs. These will be dumps of official EPROMs. Pick the files which match the original stickers on your games.

Thank you,
"No letter means the EPROM has the first issue of the data, A is the first revision and so on"
> but I thought that the 961004 version was the second one, so why is it the letter "i" and not "B" ? Because it counts all regional versions too ?
