[FR] BMSCPU64 (Super Cpu 64 version) #53

Closed lroby74 closed 5 years ago

lroby74 commented 5 years ago

Would be nice to have Bare Metal SCPU64 version, this is not activable via VICE.INI, is another kernel required (like C128) :)

This may be better than BMC128 for have many accelerated games

I tried it but it was too slow. I don't think the Pi has enough horsepower to emulate the 20Mhz CPU + video + sound. If you find a version for the Rpi that emulates a full 50 fps, I can look again.

I also wanted to ask about scpu version. I have tried VICE on Raspbian on RPi 3B+, but it could only achieve about 25-30% of the real speed. The reason I still wanted to ask is RPi4, it should be considerably faster, maybe even fast enough.

I tried SCPU. Rpi doesn't have enough horse power to pull it off. Closing this.
