Phantasy Star II Modernization Hack + Fast Walking patch not working

[lucasstinis]

I have tried to run the Phantasy Star II Modernization Hack v4.0 using the current version of the OpenFPGA Genesis Core (0.4.2) without any issues, but after adding the Fast Walking patch, it doesn't manage to start anymore, resulting in a red screen. I tested it in Kega Fusion and it runs fine.

Note I checked the CRC of the resulting ROM and it conforms to what adding both patches should result in.

I also tried the Fast Walking patch on v4.1 of the hack, with the same result. After this, I tried fixing the headers of both versions of the Hack after applying the Fast Walking patch, using this tool. After doing this, v4.0 still resulted in a red screen but v4.1 at least loaded... to afterwards crash as soon as the game has started (i.e. character is showing) and I press any button (move, open menu screen, etc.). When trying to run the versions with the fixed headers on Kega Fusion, only v4.0 worked correctly.
