I'm having a problem with DGen on the current PiMAME image (at the time of writing, this is 0.7.9) on my 256MB Model B Raspberry Pi. Everything else works fine, but after I choose a game to play in DGen, it drops to a black screen and never does anything else (there's no sound or anything, either, as you might expect). It doesn't respond to inputs from anything, so it's necessary to cut the power in order to reboot the RPi.
I know from one of welshy's very useful posts that on a 256MB Raspberry Pi, DGen requires all of the RAM to be assigned to the ARM and none to the GPU, so I tried changing the memory-split to that, but unfortunately it didn't change the behaviour I'm getting.
I'm at a bit of a loss as to what to try, because (obviously), I can't readily see any way of tracing where the problem actually is.
Has anyone else encountered this, and does anyone know of a solution, please?
Thanks very much in advance.
