I know you would have to make it from scratch, that is the point! Listen, I'm not talking about running dolphin on an G4, I want to discuss if it would be easier to make a more correct emulator for a G4 CPU (not running in full speed but being able to interpret the OP codes more natively) since it is also a PPC.

This is very tolling on the cpu and a PPC g4 is with 100% certainty not powerful enough for emulating non-native code at such speeds to achieve anything playable. The JIT recompiler also compiles all the emulated code real-time when you run any game. The broadway processor in wii is a significantly modded IBM 750CL with added support for paired single point calculation and additional altivec instructions. Dolphin is made for the x86 platform.Īlso, gc/wii's PPC code will not run natively on your PPC iMac because it addresses RAM differently & has a lot of custom instructions which are not present at all on your home PPC.
I don't think any coder is willing to take part in such a massive project just for maybe a dozen potential users. If you'd want to run dolphin on a computer with a PPC cpu, you would literally have to code everything from scratch.
So dolphin can't be even used or compiled on Mac OS X if you don't have an AMD or intel cpu. Dolphin currently needs at least SSE2 to operate.
No, but it's a lot of work for practically zero benefit (little to no userbase).Īn old 1.5ghz ppc g4 very likely can't handle the amount of floating point math per second and output & reading graphics card/random memory data like the ppc cpu inside the wii/gc.Īlso, it uses an entirely different, IBM proprietary instruction set for cpu commands.
