[CDG5] MemRetry's objective

[Max Poliakovski]

Wow! I call it a "real quick" reply :)

Mainly misaligned accesses. An emulator might not complain about these, but

So PPC load/store instructions will cause DSI on misaligned access and
memretry will magically fix that? That sounds cool :)
I don't actually know how the emulated CPU in MAME handles misaligned
accesses. Tomorrow I'll try to enforce it to see what happens...

Currently it doesn't because MAME's emulation is still incomplete. Two
years ago, I sent them several patches fixing CPU emulation so their model
of a PowerMac 6100 almost reaches the gray screen. A hardware emulation
issue related to CUDA/NVRAM is currently preventing it from booting - it
seems that external interrupts won't be routed as expected. That causes the
Netboot driver to hang forever. I think I'll be actually able to fix it...
