Commander Keen has a separate Music Configuration Menu. This way you can use one sound device for sound effects and a different sound device for music.

I guess there's a bug in the video memory detection code. If you're sure you have the 128 kB memory upgrade, then ADJMEM isn't necessary and you can use -HIDDENCARD to skip the video memory check. Tandy music can be enabled in the Configure Menu. In all versions: CGA, EGA, MCGA and Tandy 1000.

It's for when you're playing this game at work and your boss complains about the noise. True story.

Awesome! BTW, I just releases a new version of Doom8088. Now you can disable the PC Speaker sound effects by using the command line argument -nosound or -nosfx.

Doom8088 uses 1.5 MB of Extended memory if available. It loads the whole WAD file into it. So basically Extended memory is used as a RAM drive. Doom8088 uses exactly 64 kB of Expanded memory if available, even if more Expanded memory is available. If less is available, Doom8088 doesn't use it...

If the WAD file doesn't fit in XMS memory, the speed of the hard disk has a big impact on performance. So it hard to say it runs 3-4X faster than a 4.77 MHz 8088.

You could also try the MDA version (80x25 monochrome text mode). It also works on non MDA systems.

D286MY.EXE -timedemo demo3 is the command you're looking for. There's also the IDRATE cheat which will show the current frame rate.

BTW, I checked in 86Box and the first level can be completed on a machine with 448 kB of RAM.

The minimum requirement for CPU is a 8088, for RAM I'm not sure, the more the better. The 40x25 16 color text mode version is the fastest version. You might want to start with that one. Preprocessed WAD files are included. I'm a bit surprised the CGA version isn't that much slower than the VGA...

Doom8088 in everybody's favourite video mode: CGA 320x200 4 colors.

The latest release adds support for EGA 640x200 and 320x200 16 color graphics modes and the MDA 80x25 monochrome text mode.

With some preprocessing of the title screen, the "Software" part of the id logo can be made readable. Using these text representations requires some code rewrites, because most of the code expects the video memory to be filled with the checkerboard character.

Googling for Doom16 shows results about the 2016 Doom game. I've came across the misnomer Doom88 which I think is pretty funny. It's as if this port came out in 1988. Anyway, in the last 10 months support has been added for Mode Y, and 80x25 and 40x25 16 color text modes. The WAD file is...

Two mistakes: 1. rep movsb copies 16384, rep movsw copies 16384 * 2 = 32768 bytes. 2. You can't set ds and es directly. You need to do something like mov cx, 0C800h; mov ds, cx.
