Official Squeeze does not support Super-H.  This is an unofficial port that
started out as an early Wheezy/Sid, and got (mostly) downgraded to an
incomplete unofficial Japanese port of Squeeze.  It mostly suffices to compile
DIET-PC at a more-or-less Squeeze level.

The QEMU SH4 emulator performs very poorly, but seems reliable up to QEMU
version 1.2.2 (1.3.x encounters random segfaults in userspace).

QemuManager 7 doesn't support the SH4 emulator, so there's no VM2 file for this
VM, sorry.
