The Productions

Our demos, intros etc. in chronological order

Explanations of the platform icons:

MS-DOS. Various requirements from DAC to GUS.
AGA and other Amiga-like such as WarpOS, MorphOS and OS4.
Amiga OCS. For example, Amiga 500.
Generally means x86 Linux, but other ports such as PPC or AMD64 Linux might be available.
Atari Falcon030
SGI/IRIX. For 6.5 systems. Some ports require a few SGI Freeware libs.
Other Unix. Typically Solaris, NetBSD or FreeBSD.
BeOS x86 PE
The boring Win32 systems ranging from 95 to Windows 7 and beyond. Pretty much everything should run on XP.
Mac OS X. Older stuff is PPC only, so you'll need Rosetta.
GamePark GP32, the Korean handheld.
GamePark GP2X, another Korean handheld.
Dreamcast. Stuff should work equally with PAL, NTSC and VGA.
Maemo 4 - Nokia N800/N810 Linux PDAs.
PlayStation Portable. Use unofficial firmwares (developed on 4.xx M33).
Nintendo Wii. Use Twilight hack or preferably Homebrew Channel to load.
QNX Neutrino on x86. Only tested on Qemu.
IBM OS/2. Tested with Warp 4.52 only. Might require libc063 installed.
Acorn RiscPC series with StrongARM. Not extensively tested.
Mer Linux for ARM-based devices. Tested on N800.
GP2X Wiz, the successor of GP2X
Sharp MZ-700 (and probably MZ-800)
Good old Commodore 64. Tested on a few configurations plus VICE.
Sinclair QL. Not tested on emulators, turbos or later models such as Q40.
Panasonic JR-200UP, the PAL model. Good luck finding one of these.
MSX compatibles, PAL MSX1/MSX2. We'll probably leave this side to L!T in the future.
The Vectrex game console
Commodore Plus/4 and probably expanded C16, too. Use Plus4emu instead of VICE.
ZX Spectrum compatibles. Hardware requirements may vary.
Commodore VIC-20, possibly with extensions.
