I'm not in a great position to do this because I've already made some other modifications to my 32MB Dreamcast. I need to put together a fresh 32MB motherboard before I can do anything scientific. I've mostly been using my 32MB Dreamcast with my ScummVM backend which runs fine and takes advantage of the upper 16MB of RAM.
But I grabbed a stack from my collection and tried each one out for 2-3 minutes. Here are the results (all NTSC-U unless otherwise noted):
Dead or Alive 2 (NTSC-J)
Jet Grind Radio
The Typing of the Dead
Space Channel 5: plays fine, but instead of FMV background, just a black plane
Tony Hawk's Pro Skater: displays trademark screen (Tony Hawk's, not the SEGA one) and hangs there
NFL 2K1: blank screen, doesn't run
I wonder if there's some common FMV code that isn't working.
No theories, but an observation: one thing that we know will crash a 32MB Dreamcast, but not a 16MB Dreamcast, is setting the MCR's AMX bits to 4.
