Hopefully don't sound too picky, but I am an audio centric person and the difference is pretty noticable to me. Even if I'm getting a little tearing or a frame rate drop, it's worth it. Aren't there quite a few high quality sound cards for the Raspberry Pi out there that connect through GPIO pins …

Cool project! And it's also interesting to find out about the existence of Circle. I had no idea a bare metal SDK existed for the Raspbery Pi family. Although it's cool to see bare metal software being developed for the Raspberry Pi, I wonder how much actual speed gain it would offer us over a …

Would it be an idea to publish all the source code of Rudolph Loew's work to GitHub? If his code gets published there before the 2nd of February 2020, it will be archived in the GitHub Arctic Code Vault for future generations. What better way to preserve his legacy?

I wonder... Since many Tandy 1000 supporting games used a simple detection routine that basically searched for the presence of the string "Tandy" in the BIOS code, did many games trip on machines like these? Tandy 2000 and Tandy 3000 systems had no support for the special graphics and sound …

The SNDBLAST.DRV file should go in the same folder as the existing .DRV drivers that come with the game. I believe that's simply the game's root folder. Then you have to run setup.exe (or was it install.exe?) and select this sound driver. I can't remember whether the setup/install programs would …

Your second paragraph makes no sense. That was actually not a crazy question. A DOS extender does all sorts of stuff that advanced users might want to tweak. DOS32A for instance is a drop-in replacement for DOS/4GW and can optionally be configured with an environment variable, as documented here: …

Also, many games (unfortunately) did not allow for the music and digital audio to be configured on separate sound devices. Gods was one of those games. Either you would have FM music with digital audio (if you let it use a Sound Blaster), or MT-32 music without digital audio. For some such games, …

Have you tried configuring MUNT to emulate a Roland CM-32L or CM-64 instead of a regular MT-32? Those later models added 33 sound effect samples specifically for games. The MT-32 lacks those samples. Not all games make use of those sound effects, but some of them do. Give it a try. See also http:// …

I'm using SeaBIOS in my emulator, but if I remember correctly it relies on the remapping support in the chipset to decompress itself to RAM.

Not at all. ethflop does not emulate a floppy controller - what it does, is emulating a floppy BIOS by intercepting int 13h requests. It's a kind of 'overlay' that goes on top of the machine's BIOS, effectively replacing it for floppy requests. Ah, at the BIOS level. Got it. :blush: ethflop is …
