This YT video shows a user's system startup commands for the card. Those commands are just the usual kind of initialisation commands, so I don't know whether any help is gained, but at least we see a working example of the same card - doing GM - and some parameters. https://www.youtube.com/watch?v= …

Fpgas are just emulation. Emulation is one of the most exciting and advanced areas of computing and hacking, so "just" is quite a stretch. You, in another thread today, about the PicoGUS : Every time you update this, I get more and more excited to buy one! This is seriously one of the best retro …

Welcome to the forum! Hopefully you'll find that it's a useful, welcoming place, as many of us do. Thank you! I'm sure I will! Then, from the command line, use only UNISOUND /CL . The purpose of that is simply to list the ISA Plug and Play cards that it finds. We first want to know if it is able to …

My limited take: While we can be certain that a great deal of comparison was done across the years of Ultrasound emulation development (from DOSBox to PicoGUS, etc), I'm not aware of any structured scientific comparison that exists, to compare the different options - e.g. the mdfourier gold …

At $50, the PicoGUS sounds like quite a device, but as a longtime owner of a classic Gravis Ultrasound, I wonder how well the RPi core can approximate the GUS. The PicoGUS would not have the >12 voice drop in frequency limitation obv and it's just playing samples and I doubt the GF1 put a lot of " …

This might be (my latest) dumb question, but does there exist large-scale testing of Picos being overclocked? E.g. 100+ random Picos, all overclocked and analysed, for statistical results? I was just idly wondering if perhaps 1 out of 100, or whatever, might not like the overclock. This seems less …

@polpo Updated FW on my 1.1 to 1.0.1 - LED is certainly more informative now :) Regarding gamepad support - i don't seem to get any power from Pico's USB port.

By comparison: Considering the retail cost of a 9202 blank bracket - a few bucks apiece plus shipping, for a hobbyist making a card or two - not to mention the effort of accurately drilling the holes at home oneself, the abovequoted $3-4 (after shipping) per fabricated bracket seems very reasonable …

Will the v1.1 boards still be supported by ongoing future firmware releases? or, to ask another way, will the v2.0 boards get features/functionality that the v1.1's cannot do? All boards will run the same firmware! There are some hardware differences on the new board that have to be handled, so the …
