Porting DOOM To The Casio Loopy

Targeted towards refined female gamers unlike the savagery of the mainstream game consoles of the era, 1995’s Casio Loopy was a bit of an oddity of a game console. Despite being standard enough in its design and backed by the might of Casio, it saw only one year of active software development and hardware manufacturing ceased by the end of 1998. With only eleven titles released for the system, with none of them being Doom, this obviously terribly upset [Throaty Mumbo], who set out to right this egregious wrong.

For the two dozen people or so who have one of these systems, you can experience the fruits of his labor yourself via the GitHub repository and something like the FloopyDrive cartridge.. Despite the quite capable Hitachi SH-1 16 MHz CPU and 1 MB of RAM, the main limitation is probably the original 2 MB of ROM space that does not leave a lot of space for DOOM WADs, even after doubling it on the FloopyDrive. Correspondingly you only get a handful of levels out of it.

Overall game performance isn’t too bad, though in the port’s current unoptimized state the resolution is fairly low. That said, even the console’s built-in printer is supported and demonstrated in the video, which is a pretty nice touch. It’s not like Sega or Nintendo consoles allowed you to screenshot those glorious headshots.

  1. anecdotally, in the 90s, the girls i knew played nintendo games like mario and zelda. ironically, the one pc game i knew more than one girl to play was doom 2. oh and solitaire

    1. Mostly early ones which’d require a demake. Here’s a list based on my archive of systems thru to the end of letter C:
      APF Imagination Machine
      Atari Jaguar CD (non-CD exists; idk why you’d want to use CD addon specifically, but idk why you’d port Doom to Casio Loopy)
      Atari 7800 (tho it’s backwards compatible; there exist demakes for 2600 and 5200)
      Apple I & II (I see an Apple II Doom demake titled “joke demo” online, tho idk how complete it is)
      Bally Astrocade
      Bandai Playdia (the idea of this amused me; good luck, someone, some day)
      Bandai RX-78
      Bandai Wonderswan (nor on the Color; this one surprised me)
      Casio FP-1100 (same with PV-1000 and PV-2000)
      Probably nothing from Cheer-Tech…
      Coleco Adam or Colecovision (though demakes run on Z80s)
      Camputers Lynx (Z80)
      Comx-35
      Cybiko / Cybiko Xtreme (tho check out Lost in Labyrinth)

      non-graphical systems excluded; list increases 50% or more if you include them.

    2. Does the VTech Smile have Doom?
      Fairchild Channel F?
      (the Channel F should at least be able to run a demake)
      The Coleco TelStar is a SuperPONG console (although not related to SuperPONG, just a co-evolution). In theory, since the entire game circuitry is on the interchangeable cartridges, shoving a RasPi Zero or something in there should do the trick.

      And no, I’m not porting Doom to the Interton VC4000. You try getting it to run with 37 bytes of RAM (with a maximum of 7k for some reason) and 4 sprites which is pretty much all the console can display. At least the VC4000 has Flappy Bird (but boy does it suck!)

  2. I watched the video and other videos by this guy and people are heavily speculating that the ports are being made by AI due to his heavy reliance of AI within his content, I really hope its not.

    1. OH NO! WHAT IN THE HEAVENS SHALL WE DO?!?! AI??? DEAR GOD!!!! SOMEBODY SAVE US FROM THIS MADNESS!!!! PORTS TO OBSCURE LEGACY HARDWARE ARE MANDATORY TO TAKE AS LONG AS POSSIBLE, USING AI IS SOULLESS AND CHEATING!!!!!!
