QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL
|
|
|
|
|
VGA BIOS.

QEMU uses YM3812 emulation by Tatsuyuki Satoh.
|
|
|
|
|
|
|
|
|
|
QEMU uses GUS emulation (GUSEMU32 http://www.deinmeister.de/gusemu/) by
|
|
|
|
|
Tibor \"TS\" Schütz.
|
|
|
|
|
|
|
|
|
|
Note that, by default, GUS shares IRQ(7) with parallel ports and so QEMU
|
|
|
|
|
must be told to not have parallel ports to have working GUS.
