At the time, even the cheapest adaptors used to include locking brackets. These were basically plastic shims with a slot that fit over the card, and a plastic latch that would clip into a cut-out on the standard SECC2/universal retention modules.

The 5.6 MiB .PAT set is the original UltraSound 16-bit patch set. It is available on the GUS PnP installation CD as SETRAM.EXE (in the SETUP sub-directory, I think). It belongs in the MIDI sub-directory of your installation (so \GRAVIS\ULTRASND\MIDI) by default, and will be used when you install …

good news btw: my IW ROms from UTsource came this week and i soldered them today, and TAAADAAA ! It works. At least the MD5sum is correct, now i have to get some sound out of it. using duke3d and darkforces setup to test sound. edit: no soundouput for MUSIC with GUS set up .... Do those titles …

Finally, after a good deal of fiddling with the receptacles and re-soldering, the ROM module sandwich is working reliably. There is still a problem with the instrument map that causes the percussion to produce garbage, rather than proper playback, but only on bank 0. The other percussion banks seem …

I think I've found and fixed the problem I was having with the ROM. It turns out that, despite being soldered down, one of the pins seems to have been slightly out of shape, and wasn't making proper contact within the receptacle. I re-heated it, and gave it a gentle nudge with the tip of the iron, …

It's nowhere near final, of course. One problem is that this configuration obstructs at least one neighbouring slot. The idea behind this design was that I could use the same ROM modules as on the Gravis board, so that I could be sure that that aspect of the design works, and can verify that the …

yeah but cpu cycles will still be a problem. its more intressenting for faster machines. Actually, if you extend Scali's idea a little and include an MCU on the board, you can actually cut down on host CPU usage significantly. With the right design, you could probably bring the number of writes to …

So where do I get such processed files *.iwl to use the RAM configuration? As far as I'm aware, they have never been distributed. Even if you were to find the file(s), they are only for IWSBOS, and are usually 1 MiB or less. I don't understand the apparent obsession with locating these files; the …

Is OPL3 "perfectly" backward compatible with OPL2 ? Basically, do we need to bother with both OPL2 and OPL3 on the board, or just OPL3 is enough ? Of course, it's always possible to disable additional features of OPL3, so software would detect it as OPL2... My hearing probably isn't good enough to …

In the documentation I read there is no mention of control chip being mapped behind MMA on level 2 cards, only over OPL3 2nd bank. And on level 1 there is no control chip/mixer/optional boards and therefore no possible conflicts. Just OPL3 and MMA. mapped at 388 one after another Now that you bring …

This is all hypothetical, of course; I'm still not convinced this is worth your time. At best, you might be able to get such software running, but how close can more modern hardware come to the actual Gold sound quality? Still, unless I'm mistaken, that overlap exists only in the case of phantom …

AFAIK MMA only serves as bus address decoder for OPL3. For all purposes it can be considered transparent if we are only concerned with OPL3 (and if mixer is alreadty set up properly). 4 MMA chip regs follow 4 OPL3 regs and the method of accessing its state mirrors OPL3. I may have had the address …

Yea, Dune is a bit of a shame... It's one of very few games with OPL3 music, arguably the best OPL3 music ever made for a game... and it has a very strict AdLib Gold detection routine, so it really doesn't run on any other OPL3 hardware. It's as if Dune was meant as a promotion for AdLib Gold. I …

So, it may be worthwhile to emulate, for games that only play OPL3 FM on Adlib Gold and try detecting it, instead of running generic OPL3 detection? I'm not sure that would be worth the effort. There were very few titles that even tried to use any of the features that would make this relevant. Most …
