So the first thing you’ll need is Neko Project II.  It can be a little hard to track down downloads, but there is a whole slew of them here:

https://simk98.github.io/np21w/download.html (it moved again)

So for now this link, is the latest build, which was last updated on

Extract that, and rn np21nt.exe

You’ll want to configure the sound.

If you choose to use the MIDI you’ll have to map them to a MIDI-OUT port, and I used the default Microsoft GS Wavetable.  Of course you could use MUNT, or any other MIDI mapper or port.  Also you may want to setup the serial port MIDI as a backup plan.

The sound effect settings work best for the PC-9801-86 audio board.

I’ll save installing MS-DOS, and installing DooM for another fun episode, but to configure DooM.

Run setup.exe to setup DooM!

The menu is simply:

• 1 graphics
• 2 Background Music
• 3 sound effects
• 4 not sure
• 5 controller

The PC9821A driver works best from what I’ve done in my limited testing.  I guess if you had a different emulator, or a real PC-98 you’ll get more out of this.

Next is the BGM or music

You really have 2 options here, #3 for the PC9801 driver which uses the YM2608 chip.  Or the General MIDI either option 4 or 6. I didn’t notice any difference between the two of them, they both sound kinda slow, but workable.

Now for the audio board, select the PC-98

The PC-9801-86 is what you want here.  Now with either a 100% PC-9801-86 config, or a 50/50 of the MIDI/PC-9801-86 we are ready to run DooM!  Selection option 6 and away we go!

And all being well you’ll get the start of DooM!

Otherwise, you’ll get this fun error:

In this case I had emm386.sys in my config.sys which conflicts with the dos extender DX386.

Personally, I find it easier to boot off the #1 install diskette which will automatically start DooM!

If you are feeling brave, listen!
