To give a little background, when I designed the MIDI out port on the PicoGUS I went with Type A because that's what the MIDI Manufacturers Association officially recommends. If I knew at the time that the PCMIDI cards used Type B, I would have gone with that instead.

Should "ultramix" let you set volume with picogus? It's something I'd also be interesed in. "Could not locate an Ultrasound at the port(s) specified in the environment" and tells me to run SETUP again. Happy New Year, btw :) I haven't implemented any mixer things so that's not possible for now. …

Speech Thing is so trivial that I've put off doing it forever, and Disney Sound Source isn't much more complex (adds a FIFO). I might consolidate the other simple modes (Tandy and CMS) into a single one that also adds Covox/Sound Source. I actually made an attempt at SSI-2001 and HardSID emulation …

Congrats, what an awesome release! 👍 Seeing as DOS gaming is incredibly well served by the GUS mode already - the SB16 mode is most exciting for me personally for Win98 usage, and the lack of OPL3 there isn't a concern at all. However, circling back to our chat about Win98 and the possibility of a …

I think the NE2000 idea is very cool idea, thanks! I am curious if you can set a picogus in the NE2000 mode firmware, while also allowing a second picogus to do all of the regular sound tasks? Maybe a separate card can be developed for full networking working tasks and even add ethernet …

Future development plans in rough priority order: USB refactor, adding USB device status in pgusinit and probably using https://github.com/RobertDaleSmith/USBRetro to support more joystick devices SB16 "lite" mode (aka SB16 with OPL2 - since I've been unable to emulate OPL3 on the RP2040, the idea …

just an FYI for all the joystick wonderers... The pc gameport does not utilize any hardware interrupt. Only resource used is a small IO range, mostly 0x200,1-7,8 or something. Yup, it shows up as GAME ADAPTER at 0x200 when looking through the I/O adresses in CheckIt. I just cannot get any game to …

If I'm not mistaken, multiple devices on the same ISA card could share an IRQ, but it would have to be handled properly both device-side and driver-side. Perhaps CuteMouse could be enhanced to support something like that on this card? That's certainly possible – PicoMEM does it. Its pmmouse driver …

Thinking a bit more, it might not be a large amount of current on that digital ground (GND) trace itself but arcing between it and analog ground (AGND), which is right along side it on that layer. So something to check: in any normal circumstance, GND and AGND will be at the same potential. GND and …

So a couple questions: are you using a modern PSU? And how did you have the McCake mounted? It should be like this as shown in root42's video on the PicoGUS: I am using a Sparkle branded 300W PSU, it's old enough to have an AT power connector on it and has honestly done a better job at keeping …

I had a bit of a scare recently with this card. I love it so much, and was really sad to see that something arced through it and sparked a small flame. Yikes! It looks like the digital ground going to the WT header took a lot of current and burned out. This is the second time I've seen an issue …

Ultramid is definitely a weak point in PicoGUS support, especially with early versions. If you can, run ultramid from the latest version of the GUS ultrasnd directory instead of the one that comes with the game. It works a lot better with the latest version.

Does the PicoGUS support 2 Joysticks ? either through a usb hub or using 2 PicoGUS ? Yes, you can use a USB hub to connect multiple joysticks, but the mapping will be the same on each controller (left analog stick and D-pad map to joystick 1, right analog stick maps to joystick 2). I want to …
