Re: Future sound card musings

Similar to the graphics card thread, here's some notes on possible future sound card emulations. As with that thread, nothing here should be taken as a statement of intent, I'm mostly just jotting down a few thoughts. This obviously does not cover every possible sound card, just the ones I'm most l...

Banshee will be a nice addition.
May I ask if you've hooked a 2D engine to the Voodoo renderer or you did a complete overhaul ?

Hi.
Just asking here : do you use SB DSP as Asktek DSP ?
Does it means that Aztech DSP (AZT1605-U05 , AZT2316, AZT2320 ...) functions are really on par with Creative's part ?

Re: Error: PCI Read Configuration Failure

At first, maybe you should configure your BIOS with 1.44 Mb floppy. Based on your screenshot they are configured as 2.88 Mb.
Then after, change your CPU to an Intel DX2/66 for instance and don't use dynarec.
You should also lower guest memory to 64 Mb max.
