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:
So for now this link, is the latest build, you’ll need to enter a password to download the file, it’s 9801.
Extract that, and 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!
