Try using SoftMPU with the DELAYSYSEX command argument Thank you for your suggestion! I used SoftMPU on port 330 with the "delaysysex" parameter and tested it 10 times. Both the MT-32 old and new displayed "Westwood Studios" and "Presents" consistently. I had my friend test it with his setup: CPU: …

Here's the intro (and some of the flight sim gameplay) on my 20MHz 286 machine... which plays the game really rather well and around the same speed intro/animations as your L1-cache disabled system: https://www.youtube.com/watch?v=FD18i0whLgU But you can see in the sim dogfights that when you start …

This morning, I played the DOS game Wing Commander (1990) on a Pentium II MMX 400 computer with a Roland MT-32 (FW1.07) MIDI device. The Pentium II MMX 400 has its L1 cache disabled, but the L2 cache remains enabled. I recorded a video of the game's intro (twice) and the intro of the first mission. …

For 2 and 3, they are both listed as "old version", should 2 be "new version"? Or did the device behave differently in two different tests? Yes, it behaves differently in my tests, the old version randomly drops 'Westwood Studios' display while the new version stably does not drop it.

Thank you for your test! I’ll also upload some videos of my previous tests with the physical machines: 1.The top one is the new version MT-32, and the bottom one is the old version MT-32. The MIDI signal first goes into the old version, then cascades to the new version. https://youtu.be/57KXzyQcz-A …

Recently, I bought an old version MT-32 from an online second-hand market in a certain big country. The firmware is 1.07, and including shipping, it cost about $224, which seems relatively cheap by today’s standards, right? I tested this MT-32 with DOS games, and so far, everything seems to be …

I have two Roland MT-32 devices: one is an old version ( firmware 1.07 ), and the other is a new version (firmware 2.x). They are daisy-chained using a 1-meter DIN5 cable, with the MIDI signal first going into the new version and then passing to the old version via the chain. My test PC setup is a …

It would be great if the lecture video could explain the principles behind the 'elephant dancing' animation in the AREA 5150 Demo. I'm very curious about how they managed to create such smooth animation using the ANSI-from-Hell technique.
