PowerPC "Gekko" Opcodes and Explanation

[|\/|-a-\/]

Can anybody give me a list with the Gamecube CPU's and the Flipper GPU's OpCodes with an explanation for every mnemonic/opcode?
couldn't find it on the ibm doc page...

First, get yagcd (google for it). Gecko's main CPU is (more or less) a ppc chip and has a "normal" mips instruction set (and some additional opcodes). Google for "mips opcodes", should produce billions of results.

i don't think there is a BPU or such stuff in other MIPS CPUs.
i used gooogle, but didn't know until i read that the "Gekko" CPU is similar to PowerPC CXe where to find informations on ibm.com
yagcd not describes the mnemonics and don't writes which opcode belongs to which mnemonic.
but thanks for ya answers

The biggest difference you will find between the Gekko and PPC are the SIMD instructions. But to get started with anything, the basics are there. If you need information later on about SIMD, then you can find it easily from #gcdev or gcdev.com forums.
