I recently began dreamcast emulation. It took a little tweaking with the emulators to get them running, i am using nulldc it runs soul calibur and doa2 at full speed and nearly flawless. but some of my other games will not run on nulldc, so i aquired chancast, and it runs things at like 10x normal speed. And null dc freezes on sega bass fishing, and 4x4 evo. My next attempt will be with resident evil code veronica. any help or advice would be wonderful
