Hello! First of all, thank you so much for this collection, I love it!
Second of all, I know nothing about how cdis actually work, I'm not a tech savvy person.
As a French, I was really happy to see a french version of your collection, but saddly, on the french CDI I got, PS2 is in english. So I tried to just replace the rom by a french one I had on my computer, I named the rom TMNT.GEN as it was for the english rom, and tried to build a CDI with this rom by myself. Looks like I failed, the disc is recognized as a game by my Dreamcast, but I can't get past the SEGA logo, the console reboot. I have no idea what went wrong honestly.
I only have CD-Rs (and I'm not even sure the DC can read RW), so I don't feel like rebuilding another CDI and burn it just to figure out it still wont work.
Here is the CDI, as well as the french rom I used attached below, so you can do something with it if you want :
