	This page is designed to allow for a quick look over all the drivers with a MACHINE_NOT_WORKING flag by giving, as much as possible, an idea on the amount of effort needed to fix them.		This page is designed to allow for a quick look over all the drivers with a MACHINE_NOT_WORKING flag by giving, as much as possible, an idea on the amount of effort needed to fix them.

			To editors: list only relevant MNW reasons here, don't parrot TODO in base driver.

	~~RISC OS Draw app uses unimplemented copro instructions; needs ABORT line support to the~~ ARM ~~core; missing hard disc controller, serial interface, 82c711, podules expansions~~.		Should be good enough after recent ARM changes. To be QA reviewed.

			''' aa310 -bios 0 (default)''' - Arthur OS doesn't recognize floppies

	~~PS/2 keyboard~~ doesn't work ~~properly~~, ~~CMOS settings don~~'~~t work~~, ~~pending fatalerror from ARM7 core~~.		HDD and CD-drive doesn't work, which means untestable for the specific SW list beyond occasional opt-ins from base Archimedes SW list.

			''' rpc600 ''' - no sound, probably requires IOMD support for VIDC10 compatible mode.

			''' a7000 ''' / ''' a7000p ''' - requires PS/2 mouse emulation to be usable in order to use Desktop.

	~~Has CD-ROM and/~~or ~~ARM~~ issues ~~with the custom Opera Filesystem and the bootstrap Avatar protection it does with 3do games (reads first sector, decides it's not good, bails to ROM BIOS instead~~). ~~Photo CDs detects properly punts after splash logo~~, ~~Audio CDs~~ needs ~~mods in DSPP (earlier version vs~~. ~~the one in Konami M2). User programs will eventually need custom MMU emulation~~ and ~~video improvements~~.		Startup check pretends that a VRAM of 1MB is invalid so games will break later with their Sport setup (causing more or less severe layer clearance issues in some SWs). Madam PIXC, Projector and Mult sections still needs work. Occasional non-Madam bugs here and there, SW list has many holes at current time.

	''' md23do, sht3do ''' - ALG with custom BIOS ~~featuring extra protection~~.		''' crime3do, md23do, sht3do ''' - ALG with custom BIOS for Arcade, requires lightgun emulation.

			Unemulated plain PC-8801 compatibility mode, FDC PIO mode has issues when using the actual BIOS (which means that '''sorcer''' can't boot at current time), requires CPU speed bump to avoid problems in some games (cfr. '''olteus''').
