Looks great! Good work. It is a surprisingly challenging job to get the holes that accurate, when using ordinary household tools.

Hello! I have a question. Is the project expected to create a screen on the front panel of the case and control the switching of disk images?

This is laser cutting

I have a Wavetable Pi on my PicoGUS 2.0. It fits on the card without issue. I have the one with the integrated LED that is way too thick for my comfort. I had to switch around the card slots in my computer to make sure the combo fit without impeding another card.

Currently in a holding pattern for my PCB's to arrive before I can "upgrade" my PicoGUS 2.0 with a WavetablePi. Since they're coming from PCBWay, going to be about another week to 10 days yet.

The waiting sucks. 🤣

I guess it gives me time to design a front panel area to put the LCD. I know where it's going, just got to design and print something to put it there.

Looks amazing. I wish someone produced quality brackets like that for Snark Barker... Do you take commissions by any chance? 😀

Do you have such tools at home? or do you pay somebody to do it? what was the cost?

Yes, I make to order. If you want, I can make it for you too, if you find a way to deliver it from Russia.

yes, i have my own cutting machine. cost of one piece is about $0.5

I’ll have to purchase one of them and install it in my retro office 🤣

My understanding is that the RP2040 chip on the 2.0 card is completely maxed out, there are no more pins available that could be used for external inputs or screens. So until some future redesign of the card is made there is unlikely to be a direct fit screen/button bay.

Someone could get creative and create a bay that communicates using sysex messages via the wavetable header if that's not populated. The PicoGUS already sends a midi sysex message to an MT32-Pi display if that's connected.

it might a jank solution but mimicking the pull and plug in method a button used to interrupt the usb 5v line (the trace would have to be cut and the two ends connected to a normally closed button)

Since PicoGUS emulates SB2.0, it’s probably free from the single-cycle DMA clicking bug. Does anyone know for sure?

Day of the Tentcale is notorious for single cycle DMA clicking on SB16s, I couldn't detect any pops or clicks using the PicoGUS, other than the typical hashiness of 8-bit low res samples.

Still waiting ... hopefully sometime next week my PicoGUS will have a Wavetable Pi!

Finally cleared customs! Can't wait. 😀

I've just released v3.2.0 of the PicoGUS firmware: https://github.com/polpo/picogus/releases/tag/v3.2.0
This one has a ton of fixes and improvements! Vogons member Delphius contributed a lot to this release.
A few things I wanted to add such as CD-ROM support in MPU mode I couldn't get in due to memory limitations, but there's nothing insurmountable.

General

• Settings saved in flash with pgusinit /save are now preserved when upgrading to a firmware version that introduces new settings
• Volume control is now available for all sources. For example, in SB mode, the SB DSP, OPL2, and CD-ROM audio volumes can be independently controlled. Thanks to Daniel Arnold (Delphius) for contributing this!
• DualShock 4 gamepad support has been fixed

SB mode

Sound Blaster playback has been almost completely rewritten, removing a major bottleneck and freeing up way more CPU time.

• Crashing on titles with simultaneous SB DSP & OPL2 fixed
• High-quality assembly optimized FIR polyphase resampler for much better sounding OPL2 output. Huge thanks to korneliuszo for contributing this and other optimizations!
• Direct DAC mode is back after being dropped in firmware v3.0.0
• Too-slow MPU-401 output in SB mode fixed (main symptom was long delay until music starts in Sierra titles)
• CD-ROM speed now faster in SB mode - improved from 2x to 3x

pgusinit

pgusinit has been almost completely refactored, thanks again to Daniel Arnold (Delphius). It not only helps future maintainability but brings new quality of life features:

• Long output like CD image listing and extended help text now pauses instead of scrolling off the screen
• Progress bar when flashing firmware instead of filling the screen with dots
• More helpful text if there are missing arguments
• Values can be set back to their default values with a default argument. Example: pgusinit /cdport default
• Added support for volume control via commands like /sbvol, /cdvol, etc.

I read that the latest firmware version (3.2.0) fixed direct DMA, but I still can't get SB mode to work in Crystal Dream, Scream Tracker 3 or Impulse Tracker (there I stopped trying I have to admit). All three worked fine with firmware 2.1.0. I never tried 2.2.0 because it claims my ULTRASND variable is not correct (which it is).
I don't know what could be wrong, maybe I overlooked something because I ignored the earlier v3 versions because I knew SB mode had regressions.

I’ll double check those titles, however while I’m not sure about Crystal Dream, ST3 and IT don’t use Direct DAC mode. Scream Tracker 2 does, though. The only other title that uses it that I can think of off the top of my head is Star Control II.

Not sure why the pgusinit that came with v2.2.0 didn’t like your ULTRASND variable, I don’t remember it handling it any differently.
