Release v4.0.0 · polpo/picogus

New features/changes Sound Blaster 16 SB mode now emulates a Sound Blaster 16. I had a somewhat-working implementation of the SB16 DSP in late 2024 but was discouraged by poor compatibility in Wind...

@polpo Yeah, I'd still be wary...

Cuz #RAL ain't really a problem.

  • Unless you use RAL 4010 ( #E20074 ) as a telco provider, then you can expect DTAG to come after you with disrespectful quickness, but that ain't the problem here...

I do like how your projects are done with such care and detail as to seamlessly fit in, regardless if #PicoIDE or the #PicoGUS, which obviously got the closest possible solder mask colour to the original...

  • Certainly the PicoIDE is a good option for all those that go "OPTICAL MEDIA BAD!" and just want a convenient option for their legacy/ retro setups.
    • Similar to how the #GOTEK Floppy Emulators and #FlashFloppy really solved that problem conveniently...

@polpo Same, but I guess you'd not have started the #PicoGUS project (nor would've @rasteri done the #Wee86 & #WeeCee) if that was always the option.

@polpo nifty…

Granted, I do like the #PicoGUS because unlike the #Wee86 / #WeeCee by @rasteri it doesn't rely on new old stock of #CS4237B / #CS4237 sound chips, making it a more longerm-sustainable option…

  • And having alternate options is important!

When I said #PicoGUS wasn’t being left behind, I wasnt joking! This is a regular ol’ PicoGUS being a Sound Blaster 16, detected and working in Windows 98:

Just because I’m deep in getting #PicoIDE into production doesn’t mean that #PicoGUS is standing still. Delphius and wbcbz7 are in the middle of implementing some pretty awesome things (and on the original RP2040 hardware)! Keep your eyes peeled 👀

Some may not realize it, but the #PicoGUS and #PicoIDE logos are in a custom typeface that I made based on the Gravis logo from the Ultrasound Plug & Play box.

Oh no. There was a foil on my #picogus sticker all this time? It just fell off. I think it was meant to be peeled off…?

Acabo de descubrir #PicoGUS y #PicoMEM, y no sé por cuál decantarme. La primera me daría una tarjeta de sonido de gran calidad para mi 286 o mis 486 y me crearía un CD-ROM virtual en SD, pero la segunda me permitiría ampliar la memoria (4Mb EMS), usar discos duros virtuales en una tarjeta SD o conectarme a WiFi para usar ftp.
