Problem for Dreamcast emulation

Hi all,
I don’t unsderstand why Flycast works but not Reicast. There’s any option to activate?

Can you help me for reicast on a raspberry pi4 svp? It doesn’t work…

Ok, I understood that flycast and reicast are the same one…

which game are you having problems with? So far I’ve gotten ‘chuchu rocket’ to work.
