CD-ROM Drive Emulation on the PicoGUS!

PeerTube
@gloriouscow If you're making a whole ISA card, then you're overlapping with #PicoMEM, #PicoGUS, and #PicoIDE which could be a good place to steal from / ask about!
#PicoGUS v4.1.0 firmware is released: https://github.com/polpo/picogus/releases/tag/v4.1.0
Highlights:
- ADPCM support in SB mode
- pgusinit won't complain your BLASTER variable is malformed (unless it actually is)
- Revamped MPU-401 that acts more like a real MPU-401 and uses way less SRAM
- Fixes loading .iso images in Win9x w/ MKEPanasonic driver by handling lead-out
and more in the changelog!
Release v4.1.0 · polpo/picogus

Fixes/improvements SB mode Sound Blaster ADPCM playback is now supported (4, 2.6, and 2-bit modes). This allows for sound effects in Duke Nukem 2 without needing to patch the game. Thanks to Tube ...

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...

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.
