[Coco] Which Coco Emulator for Raspberry Pi?

[Bob Devries]

Veering slightly OT here....

Is there a way in SDLMESS to change the RAM size of the emulation? 
Currently it is set at 512K.

I found that if I start mess while pointed to the $HOME/.mess directory, 
it behaves better. It doesn't remember the last-used disk images, though.
