Hey I don't know wether this is the right section to ask this and if it's legal or not. Anyway, here goes nothing ... According to (some very simplistic) research, the XBOX 360 has a PowerPC Tri-Core Xenon CPU in it. So as the name suggests does it work with normal PowerPC architecture assembly? Upon further investigation, it apparently shares some similarities with the PS3's Cell processor. But Wikipedia (yeah yeah I know ...) says Xenon is based of a "slightly modified version of the PPE (Power Processing Element)", but I haven't found any further information. Also the more information I dig up, the older the info gets. I don't want to know how the Power architecture came into being! I want to know how it works! Uuuuh... got a little sidetracked there. So my questions: Does normal PowerPC assembly (32bit) run on a Xenon (preferrably assembled with VASM or something)? Does the Xenon house 64bit architecture? If so, how does it work? Is there an assembler specifically for the Xenon Tri-core? Or any other documentation on this matter? Somewhere(can't recall where), I read something about 64bit on PowerPC consisting of 2 32bit registers holding values and then just clustering them together. Is this true? I'm fairly new to assembly, so hopefully my questions aren't too stupid. I just got 2 Non-working XBOX 360's at my place. One of which has the red-ring-of-death (=>fixable) and the other has some other wierd problem (not CPU related, I believe). And since I'm a curious little human, I thought I ask, before soldering out the CPU. I hope you can help me. Greez Beliriel
