I had an idea for an XBox emulator, but I have no idea on how to implement it, nor do I feel I have the skills.
But, that aside, here is my idea:
bochs: The Open Source IA-32 Emulation Project (Home Page)
with that x86 emulator, you can load custom BIOSes, etc... and I was thinking that this might be usuable as an XBox emulator, but I have no idea, heh.
Is this possible, or do I just have high hopes?
It also supports graphics card bioses, iirc.
