Weekend achievements:

Install Mac OS 7.5.3 m68k in QEmu, although I don't know how to move data in & out yet, only in through ISO & floppy image files.

Get Windows 3.11 working at a higher resolution than 640x480, no small feat because compatible Cirrus drivers don't like QEmu's '-vga cirrus' option, & the usual SuperVGA patches don't like any of QEmu's VGA options.

Get mGBA to run Gameboy roms in blissful silence, so I don't have to rely on Mame for that.

All in FreeBSD as host OS.
