Re: OPL2LPT

in Marvin \ Sound
USB-to-parallel dongles certainly won't work. Those can only drive printers, not other parallel port hardware. A PCI-Express parallel port will work. (If you have a laptop with a ExpressCard slot, that will work as well.) On the software side, there isn't much support for Windows. Serge has an …

Re: Lotech Tandy Soundboard - (mostly finished)

in Marvin \ Sound
Well, here's a quick TSR: http://github.com/pdewacht/lotech Obviously untested. Should work with QEMM. (EMM386 doesn't allow intercepting port 0C0h. With EMM386 it still listens on a few other ports for later Tandy's and IBM PS/1, but that's of very limited usefulness.)

@Megadisk Works for me with Jill of the Jungle shareware version 1.2 downloaded here. @MadMax2023 In the INSTALL program, "Select Sound Card" -> "No Sound" and "Select Music Card" => "Sound Blaster or 100% Compatible". The hardware settings don't matter.

@MadMax2023 The non-working games in your list seem to all be protected mode games. Protected mode became common in DOS games starting from 1994 or so -- a telltale sign is that the system requirements include a 386 and 4MB RAM. And of course the iconic DOS/4GW startup banner. Protected mode games …

Re: OPL3LPT : OPL3 FM Synthesis on parallel port

in Marvin \ Sound
Author of the OPL2LPT software here. The OPL2LPT TSR currently strictly emulates an Adlib card. It intercepts the Adlib port range and transfers the commands over the parallel port. So the TSR works with any real-mode game that would work with a real Adlib card. If you want to test compatiblity with …

I've made a new release of the OPL2LPT software. Download it here. New features: - The "patching" optimization/hack now also works with QEMM and JEMM. Previously it only worked with EMM386. (@noop: this should solve your problem without new command line switches :happy:) - ADPATCH can now patch …

Megadisk: In case your system does have a 386: You'll get best performance with EMM386, but you'll need one of the last releases. Maybe try taking the EMM386.EXE from MS-DOS 6.2 and see if that works on your system. (Did DOS 3.30 already include HIMEM.SYS?) If that doesn't work, try JemmEx (http:// …

Well, that's a pretty eclectic list of games. 4D Sports Boxing: Works. Blake Stone Aliens of Gold: Works. Blake Stone Planet Strike: Works. Dune: Works. Dune II: Works. Epic Pinball: This game doesn't support AdLib. Eye of the Beholder: Works. Flashback: Works. Prince of Persia: Works. Raptor Call …

@norduk I tried Loom (EGA version) and it works for me on a 233MHz Pentium, but I checked the code and the Adlib timing looks like it might be dodgy on sufficiently fast computers. You'd probably have the same problems with a real Adlib card. If you could get EMM386 working, that might help. With …

Re: OPL2LPT

noop, thanks for the bug report. Dealing with JEMM is not that bad. The first thing to know is that JEMM's JLM modules are ordinary 32-bit Windows DLLs. You can use any tools you like, as long as they can produce a Win32 DLL. The big annoyance is that JEMM's internal API is almost entirely …

Re: OPL2LPT

AnacreonZA, you might not have the latest version of the TSR. It should say "Patching enabled" when you load it. Download it here: https://github.com/pdewacht/adlipt/releases/ If you do have the latest version, I'll take a look at what Flashback is doing. I hoped I had eliminated the slowdowns on …
