So I'd have to pair the PicoGUS with a PCI sound card You don't have to pair the PicoGUS with any other card. But I thought the PicoGUS doesn't really serve as a Windows soundcard, and the SB emulation isn't as full as something like an ESS card? I'd like the flexibility to run some things in …

I thought most stuff emulated on the PicoGUS came from DOSBox Some does, but with the important modifier, "...on a Pico, in an old PC". Even where there's pre-existing code, the amount of dedicated work required to add each new sound mode to the PicoGUS varies from relatively trivial (with basic …

Loneliness, and feeling angst towards society/other people, is a fairly natural combination. Somewhat of a 'vicious cycle', even. Challenging to break out of, if your day is spent constantly ruminating in the notion that your loneliness is justified or even *forced* by the outside world.

I have started designing a sort of companion card that will help fill in the gap for some things not included with the PicoGus, like the ability to mix multiple internal inputs like CD-Rom and a wavetable header for those who built PicoGus v1.2. It also will include a few other features that will …

Hi, I'm currently waiting on a picogus 2.0 that I've bought from a builder here in New Zealand. I'm very excited as I've not been able to get my soundblaster card working and as nostalgic as the PC speaker sounds are I'm doing to get some sweet soundblaster/GUS action. Just had a question as to why …

Games get kinda old and they don't solve the big problems in individual's life. Just a temporary escape at best. I still muster up the will to play some old Call of Duty these days. I remember playing Prototype games sometime after a COVID-19 pandemic started and some Halo: Combat Evolved at a bit …

Thanks! I'll give it a go with the magnification of the soldering 'helping hand' that I have. If this isn't enough I'll have to invest in a USB microscope (amazon, et al) for a better magnification.

Interesting, could you elaborate on that?

Over the years, the majority of issues observed with PicoGUS self-builds has turned out to involve careful attention to U2/U3/U4. Even people with the skill + experience still have a tendency to rush it, and miss a small detail at first. I know I have, on more than one occasion. Interesting, could …

What speed is the system's ISA bus clock running ? Picogus is best at ISA bus clock of 8.33mhz or lower. No idea. The board is too new to have a native ISA bus, but I think most ISA bridges be it PCI or LPC should normally default to 8.33MHz (that would be 1/4 the clock of PCI/LPC bus). From the …

A little further tests on my PicoGUS board. The system is ANOVO AIMB-865, and compatibility is fair at best. I never owned a real GUS so I'm not sure if real GUS cards were also that sensitive. Its ISA slots are powered by a Winbond PCI-ISA bridge set. - Must always init PicoGUS in GUS mode via …

btw. ALIEN RAMPAGE refuses to use my real ULTRASOUND too... Weird... maybe it`s just a red herring and does not really supports GUS from the start?! It's possible. But the broader reality of "game X doesn't work" reports is that, even without any PicoGUS in the equation, any given DOS game could be …
