[PSX] Modificar o hackrom "Yu-Gi-Oh! FMII"

[apalapan]

Boa galera, eu tentei modificar as drops do jogo "Yu Gi Oh Forbidden Memories 2" (by FMBrasil Team), usando a tool "YuGiOh Forbidden Memories Tool".

Mas, cuando eu compilei a ISO novamente e tentei correr o jogo, o messagem "Game is not FMII".

¿Como podo eu modificar as drop rates do ISO, ou modificar o emulador Pcsxr?

Obrigado, and excuse my poor portuguese.

Maybe, i'm not sure... Romhackers inserted a protection routine inside this MOD. That's the cause of a warning message is showing in the screen.

Indeed, that's what I'm trying to figure out. I'd like to remove that routine, but I don't know even where to start. How can I see the code of the game, if that's even possible?

Once I can get that out of the way, I could also see if I can re-enable the option to trade cards in-between memory cards.

Use a PSX emulator with debugger. But, u need to know psx assembly to get better results.
That's all. Kind Regards.
