How much RAM does XBMC see?
You can't patch the M8 for more RAM and you wouldn't want to. It's not as good as the other BIOSes available.
Dunno if extra RAM causes issues or not, I've asked in the past but never got an answer. Hence why I asked you.
I get the impression the RAM deliminator is intended for retail games. XBMC and Surreal detect extra RAM without it, hence I assume all homebrew apps that make use of extra memory support it out of the box.
I've only heard reports of it being used on Halo/Halo 2.
