Why switching only N64 and not also for N32? The same way we should also switch the O32 one to 74Kf which also has DSP R2 and MIPS16. That looks fine only as a first step, otherwise the idea of having an "any" CPU, as suggested by Peter, looks like a good idea. That said some instruction set conflicts so we can't enable all of them in such a CPU. The name "any" can be a bit misleading in that case. Is it also the case on other architectures? -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net
