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.
