@jim said in Whats the problem with some Dreamcast games (Rayman 2 - textures - language):
Is the dreamcast emu going to be updated and developed further?
No, the emu is dead for some time. Redream, the challenger, can't run yet on a pi as it needs some ARM assembly specific code to optimize. I can't tell if it will ever happen.
The "only" chance, is to wait for a real DC emulator in Retroarch (Redream is already a RA core, but this emulator is not very mature yet), and wait that we include it in the PC version of Recalbox.
