This is, of course, minus the display code, which will slow things down a bit.
However, I was able get someone from Adobe to do performance tuning on the CPU core, and in the release player the code is a lot faster - the CPU runs somewhere between 6 and 7 MHz (I don't know the exact number, that's just what I was told). So, in theory, we should be able to play games in "real-time", as long as we don't write slow display code :-) > One other possibility would be to generate some AS3 code from a C64 > binary.
