Hello! I'm new here, sorry if I post a question that has already been answered. I searched both Vogons and the internet but cannot find the answer. I setup SoftMPU on my 486 and Munt on my Linux computer to emulate MT-32 with Munt through a serial cable and that works really great, no issues. …

Thanks for an awesome DOS menu. Recently acquired a 486 DX4 100 and wanted to have it run DOS and Windows 3.11 but also be easy for people to use at an upcoming retro gaming party. One issue I did encounter was returning to the launcher from Alley Cat - https://en.wikipedia.org/wiki/Alley_Cat_( …

Hi, DOSBox itself does emulate a "full" MPU-401 with both intelligent mode and UART mode (dumb mode). Hence, it will work with any physical connection. Be it an USB-MIDI cable or an old SoundBlaster with a MIDI cable on its gameport. But on a real 486 PC, for example, you'll need a fully MPU-401 …

Hey folks, quick question on this. I see one game that is listed as requiring intelligent mode is Space Quest III. I have only tried this so far with dosbox and a Rolan UM-One cable to the MT-32 The music did come out perfectly, so what’s the deal? Does it break elsewhere, or does the UM-One cable …

Tried all that but no go. The board gives out a single beep as expected with normal boot but image never appears. Will try to get a monochrome monitor, since mda cards I have 3 but not a monitor.

What controller cards so you have in your system? Can you remove any non vital ones? It may be CPU related. Could you reseat the CPU for 30 more times? Any dust or rust should be gone then, to make sure your contacts are ok. Also try to reseat cache (if possible on your board) and reseat your …

can you test with L2 cache off in BIOS, to see if that changes anything? No luck, crashes even worse... faster on the DOS game, and Windows setup now even crashed with beautiful garbled color screen even as soon as running the disk checks in DOS/text mode... As a side note, while I was having lunch …

I was using a Viper V330 PCI card (Riva 128), and I have a floppy emulator and an IDE/CF Adapter. Initially all went well, I partitioned …

Under Win98, it's fairly easy to use two sound cards since you can usually configure them to use different resources through Device Manager. I have a Yamaha YMF724 and an AWE64 Value installed in one of my rigs and they work just fine together. If I want genuine OPL3, all I need to do is to disable …

I would first hazard to guess that there is one RAM IC missing. There are 8, but usually you have 9 ICs in a bank, for parity. But maybe it also runs without parity. But it will not hurt putting a 9th RAM IC there. Also, I see one 640032C IC, which is probably BIOS? But below there is an empty …

Very nice little board, albeit a little dirty. Your VGA card is 8-bit or set to 8-bit already I guess? There is a DIP switch on your XT (SW-A, the red one), try setting the monitor selection to other settings (SW-A/5&6, on-on, off-on, on-off) instead of monochrome (off-off). Your board looks like …

It's mostly an issue in first person games, when you're trying to locate enemies by sound. Otherwise, not a big deal. Also, a lot of games give you the option of testing stereo in setup and reversing the channels if necessary. Did games that old as to support sbpro and not newer cards even …
