What's wrong with having both the XR385 and MT-32 attached to your SB16? I'm only using the YMFx card cause my SB16 has hanging note issues. Of course it's nice to have a real MPU401 but personally I couldn't justify the cost (bid on the last SCC-1 too...) As an alternative, the next version of …

For anyone on a budget, I'd recommend trying to source a complete PC locally from the classified ads, either 486 or Pentium. eBay is too expensive because all the retro freaks are on there, and shipping is a killer! Buying locally also ups the chances that you'll get a nice complete system with CRT …

Nice build, good to see a PS/2 port and USB with an AT motherboard. What's do you think's wrong with the USB? Checked the pinout of the header matches the motherboard? Be careful here as I have killed a M/B in the past with a wrongly wired USB header (common grounds caused a short circuit with +5v …

Thanks, have updated the list. Enjoy your new MT-32 :happy: Interestingly, I've found that having SoftMPU loaded seems to cure some games that have speed-related issues with Roland music. For example, both Monkey Island and Loom play Roland music incorrectly on my P233MMX unless I disable L1 cache. …

MS EMM386 4.46 (MS-DOS 6.0) or later is required. AFAIK no third party EMMs support the MS port trapping API. JEMM and QEMM do have their own (incompatible) port trapping APIs.

ScummVM Fullscreen Video Mode Tip

in DOS

ScummVM's version of SDL uses the windib driver by default. On my machine this means that it uses a 640x480 resolution in fullscreen mode. This gives the wrong aspect ratio for 320x200 games (Lucasarts adventures etc) and aspect ratio correction results in horrible scaling artefacts :sad: However, I …

I get hanging notes on scene transitions when using General Midi with Sam & Max (CD version). Happens even with L1 & L2 disabled, P233MMX with YMF718 & XR385. No problems when playing through ScummVM. I think there must be an issue with the GM driver in the DOS version.

Virtual Sound Blaster emulates a Sound Blaster 1.0 and supports output to either PC Speaker or parallel port DAC. I found it quite unstable and because it predates the EMM386 port trap API, it only supports running in a custom protected mode (no EMS available) or under QEMM. It's a good reference …

I've been having a problem with DOOM, DOOM2 and Rise Of The Triad where digital sound effects stop playing after a certain amount of time. Sometimes it will be fine for ages, but sometimes the sound will stop after less than 5 minutes. When this happens, digital sounds stop playing completely, but …
