MESS SVN r10795 is released. MESS(Multi Emulator Super System) is an open source emulator which emulates a large variety of different systems. MESS is a source-available project which documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators through software emulation, as MAME does for arcade games. As a nice side effect to this documentation, MESS allows software and games for these hardware platforms to be run on modern PCs.

MESS SVN Changelog:
r10795
QL -
Added support for formatting disks, unfortunatly due to the way that
MESS implements disk images interacting with the way the QL detects
double sided disks this is currently only single sided.

Einstein -
Fixed 80 column mode, added dump of 80 column rom and fixed up
emulation based on circuit traces from a real TK02 card.
80 Column mode is now usable.
