Not counting wildchip and allgear, I can do NES, SNES, any size module (8k-64k based off of what you have on here), and C64 the best. Adlib is excruciatingly slow for me to test due to speed difficulties. I think AHX would require an Amiga emulator (although it's not impossible to do, I am unwilling to do so). MOD is possible on my end, but I have concerns about testing and rendering reliability on my end. AYM requires a computer emulator that would use the sound chip, and depending on the results, I may or may not have technical difficulties. This includes exporting to the file format. Channel F is most likely a no-go on my end, and I have no clue if an emulator exists for the Mac. Deflemask is a big no-go on my end because of a platform incompatibility (that requires an Intel Mac, and I'm on a PPC Mac). Doom WAD is my least familiar format, especially when... if I can remember correctly... it is a map editor format? I have no clue on fsound. Game Boy is possible via a Game Boy emulator as long as I can correctly rig my emulator to properly handle the recording when I use Wiretap Pro. I also found some trackers that I could experiment with. I have no clue with HES, not being experienced with MML, although I suppose it's possible. I can code HTML, although depending on how fancy you get, chances are I might not be able to properly view them. I'm not feeling too good on Mario Paint due to technical difficulties on my end. I can create a Mario Paint song fine via the SNES emulator, but there are some technical difficulties on my end relating to distribution (I could in theory distribute a .srm file, which is a save file for Mario Paint. However, I'm much less confident about trying a .sho file, and so far I have yet to be able to properly import a .sho file into my emulator.). For rendering, I would just play the song direct off of the SNES emulator. I have an ax to grind with the MIDI format due to playback inconsistency, and I am especially nervous with rending my MIDI file to MP3. NSF with expansions have mixed results for me, although I have an online player just in case that should handle all scenarios. I can do NTRQ since I have an NES emulator. I have no clue on Panda Tracker. I guess I can do Renoise, but the only warning I have is with the VSTs due to a possible platform incompatibility. SAP will be a toughie because the tracker has a platform incompatibility, and I have no idea how well an emulator will be able to produce a .sap file. SAPx2 is a definite no-go since that's a hack most likely specific to one tracker. Sega Genesis is a no-go so far due to a platform incompatibility with existing trackers. I'm rather nervous about actually going for this one anyways... Sunvox is a no-go on my end because that requires an Intel Mac, which I do not have. Atari 2600 is a no-go on my end due to emulator speed problems, which messes up sound output and results in rendering difficulties. I don't think I can properly produce a VIC-20 song, although if there's a tracker out there, I could theoretically give it a shot. And the ZX Spectrum Beeper requires a ZX Spectrum emulator, which to me is another toss-up... so... on most of these, perhaps I can give them a shot, but these are pretty much no good for me to quickly learn in an hour, especially on my type of computer.
