To accompany that demo, there's a new release of the S2PTools : https://github.com/pdewacht/s2ptools/releases The Sierra driver is now based on the latest version of Ravi's original driver, and it has been fixed to work properly on 8086 and 80186 devices.

Is the programming model publicly documented, yet? You can use these routines (for DOS compilers): https://github.com/pdewacht/cmslpt/blob/master/cmslpt/cmsout.c https://github.com/pdewacht/cmslpt/blob/master/cmslpt/cmsinit.c The CMS has two SAA1099 chips: the "cmslpt_first" routines control the …

@Cloudschatze Feel free to build on ADPATCH/S2PPATCH. I've added a standard open source license to the Git repo to make that explicit. But yeah, the build system is a bit complicated, it takes a lot of steps to go from the pattern files to C code. The "making ADPATCH patches" page actually describes …

I've made a new CMSLPT TSR release that fixes this problem with two new options: First there's an option to choose a different base port, e.g. 210 or 230. I don't know how useful this will be in practice, I think most games only work with port 220. Second there's an option to put it in "Sound …

I am mostly interested in the sequence of instructions that is equivalent to "out 0c0h,al" on a Tandy, because that is presumably the biggest difference. The equivalent is something like this: int lpt_stat = lpt_port + 1; int lpt_ctrl = lpt_port + 2; outp(lpt_port, cmd_byte); outp(lpt_ctrl, 0x0C); …

Unfortunately, patching games for S2P support turned out to be a bit too difficult. s2ppatch only supports two audio engines: - the DMX engine, used by Doom / Heretic / Raptor: Call of the Shadows - some versions of the Miles Sound System. If your games come with a 'mt32mpu.adv' file you're in luck. …

You can just use the TSR (ADLIPT.EXE). (Or do you want to run the game on a 8086/80286?)

Wouldn't the ability to patch more games (as an alternative to emulation) still be beneficial to slower 386(sx) systems as well? Or would the emulation overhead be negligible even on such systems? I think performance is fine even on a 386SX. I don't have such a machine myself to test, but I haven't …

I've released a new version of ADPATCH. It's only lightly tested, but I didn't want to delay it longer... What's new: - A lot of LucasArts can be patched now. Should be nice for 286 owners. (386 owners can just use the TSR.) - Another version of the Miles audio engine, which uses the file "ADLIB.MDI …

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 …

I see the bug, 0x2C0 should be removed from the qemm_ports list. I'll make a new build tonight. The 0x205 thing is a remnant of the TNDLPT code. As Scali said, 0x205 is the port that was used by the IBM PS/1 sound card. It gets trapped and emulated just like port 0xC0. Doing the silencing that way …

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 …

I doubt it's common. The Miles drivers for example avoid probing 220h, the code has a comment saying that could hang systems with an original Sound Blaster card.

BTW all of this is completely handled in software. There's no chance of hardware conflicts. It's essentially a very primitive form of virtualization, which is why a 386 CPU is required and why it only works with real-mode software.

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 …
