Nice work. Im sure a water cooling unit will fit in there. 8-)

I think I'm going to need to get myself a fan that can light up..
I've been aiming for having no leds at all inside the case but I must admit that looks fantastic!

PicoGUS PGUSINIT.PRG v3.6.0
I spent some time today building a dev environment to compile the PicoGUS PGUSINIT.PRG that will work with the latest firmware version.

Whilst it seems to work and PGUSINIT.PRG v3.6.0 compiles after some tweaks to the .C and .H files. I offer it here with the advice it is for testing only. Your mileage may vary on using it.

Basic functionality seems to allow switching /mode and /save. The PGUSINIT.PRG is using the new v4 Protocol version.

The latest PicoGUS firmware v3.1.0 seems to have limitations when compared to the v.2.2.0 version. SB mode is not working the same for me with firmware v3.1.0. MIDI works the same, but YM audio through Soundblaster is not working.

Anyway, here is the PRG for you to play with.

First of all, congratulations! I'm testing it and it seems to work very well.
I would be interested in the passthrough mode which I obtain by hand like this:
Thank you very much!

Raven 1 (un-cased board) got some love on the weekend. Built another set of 3 RAM SIMMs and replaced 68150FN33 with 68150FN40.

Raven 1 has the LC CPU. This is my test board now.

Raven 2 was the one which got the LED lit case.

Woo! Nice. How many more Raven boards do you need?? :lol:

PicoGUS PGUSINIT.PRG v3.7.0
Again, it seems to work and PGUSINIT.PRG v3.7.0 compiles after some tweaks to the .C and .H files. I offer it here with the advice it is for testing only. Again, your mileage may vary on using it.

Basic functionality seems to allow switching /mode and /save. The PGUSINIT.PRG is using the new v4 Protocol version. Mode switching seems better in this version compared to v3.6.0. The source code for PGUSINIT has been totally refactored in the original source code.

Looks like the associated v3.2.0 PicoGUS board firmware fixes the SB mode for Raven. :D On my test Raven, Soundblaster mode now works the same as v2.2.0 firmware and YM audio is back through the PicoGUS v2. Monkey Island 2 speech is back, and Doom sound effects are back. Both have MIDI still. All feeding through the PicoGUS in Soundblaster mode.

From my tests, it looks like most PGUSINIT / commands work fine apart from the /flash command. The new volume control commands work fine (/sbvol, /cdvol, etc).

The /flash command would be nice to get working to allow changing firmware in the PicoGUS whilst sat in the Raven ISA slot. I think the code is expecting DOS based file access and this is replaced by the Raven hard disk, so some code changes are probably needed. Will look into this when time allows.

/cd commands do not work as they need disk IO which is not compiled into the modified code.

Anyway, here is the latest PRG for you to play with along with the v3.2.0 firmware for the PicoGUS board.

Hopefully the new PicoGUS v3.2.0 firmware will allow you to get YM audio through your PicoGUS soundcard.

For the PicoGUS v2 board, I use the MPU401.PRG in the AUTO folder. My PicoGUS v2 has a wavetable MIDI board in place to process the MIDI.
For the PicoGUS V1.2 board, I also add using the OPLMIDI.PRG as there is no wavetable header on this board.

Great work! Now both audio and music work in games.
But how do you get YM audio through Picogus?

With the PicoGUS in SB mode, I believe that MPU401.PRG is the key loaded late in the AUTO folder. Then the SCUMMST games have the Sound driver set to Soundblaster. Doom just seems to work without any changes or settings.
