MiSTer FPGA - Doom [Ep.1 w/ mt32-pi Roland Sound Canvas] / DOS PC-486
0I just got my mt32-pi in the mail and assembled, and figured it would be a good time for a Doom video. This is Episode 1 in its entirety, on the Ultra-Violence difficulty level with no deaths. It's also my first time clearing any Doom episode without dying, and I'm glad I was able to experience it in its original DOS form for that.
I originally started recording this with scanlines, but youtube's re-encoding process made much of the video very noisy, so I went with standard interpolation for this one. That said, the game looks fantastic with the 110_85_soft/medium filters and 115_80_soft, at 2.3-2.4 gamma. If you don't want the game to be so dark, skip the scanline filters and gamma, and just use the F11 key in-game to adjust gamma there. I prefer the black areas in Doom to be true black, as was originally intended, and not just faded. This gives the game more atmosphere and suspense as you never know whats going to be lurking around the next dark corner.
The mt32-pi is using the Audiofabric soundfont, for a very accurate Roland Sound Canvas (SC-55) implementation. This hardware uses a Raspberry Pi 3a+ along with a custom designed add-on board, to act as a midi synthesizer for Roland MT-32, Roland Sound Canvas and General MIDI, for support in games on a few computer systems. Currently the AO486, Amiga and AtariST cores support it, but you can expect other cores like the Sharp x68000 to get support in the future as well. This small kit has a transformative effect on many classic games, and for some of them is the only way to hear them with the intended sound, like Doom and Ultima 8. The entire soundtrack was composed for this target, and then ported to other sound hardware like the Soundblaster. MiSTer cores intelligently communicate with the mt32-pi and can switch its mode automatically when you load a supported game. The integration is stellar, as is the audio quality.

iD Software's masterpiece runs great on the AO486 core, and you can get even better performance with the FastDoom variant. If you played Doom when it first came out, you likely had a similar experience to this with a mid-range 486 at the time. The frantic action and split second decision making that kept you on the edge of your seat all night in the 90's still holds up decades later.
The AO486 core was considerably upgraded/improved by FPGAzumspass, whom also brought us the GBA and Lynx cores, along with enhancements to the Gameboy and NES cores.
