Its true, I get about 10 fps (avg) boost with dynarec on.while it has a "dynarec" it still cant run most games at full speed, its a badly optimized dynarec and emulator overal, that is probably compared to an alpha release at best that was abandoned after like 2 weeks so i dont see anyone ever finishing it sadly.
It sucks that the dev didn't finish what they started but that's up to him.
If this is to ever be finished it will have to be done in house by the RA devs themselves. I really hope they decide to take this on and get it over the finish line the pieces are all there..
At least Castlevania SOTN is playable just a little sound stutter.
