usb input adapters generally produce considerably large ammounts of latency when rendering from composite video. Personally I'd recommend making/using a usb/parallel port adapter for the controllers and emulating the snes. If space is an issue, substitute the tv tuner for a usb flash drive. Personal...

If they are outputs, then it is probably split by channel.

Two "squares" (lacking sweep) and a 8-bit PCM, right?

If one of said wires is grounded, then I'd assume the squares on one line and the PCM on the other, much like the 2A03 itself.

If the system has an intel chipset and the common 4.51pg phoenix bios (the ones you can customize the boot logo with generic software on), and it's not working in any mode, you're in for trouble. The only parallel port's I've ever had trouble with were OldSchool Pentium Packard Bell systems that had...

I have found a fondness to FCEUXD(SP) for it's debug capabilities. I've been hex hacking (mostly game genie codes) for a lot longer than I've been actualy writing code, so seeing the hex numbers for common things like LDA $xxxx, STA #$xx, and BEQ $xx are just natural for me. Of course I have the .as...

All unrom-based games use, instead of vrom, one single sram chip (usually an 6420, but I've seen 6116's work fine) alongside a PROM for the PRG-ROM. If you still have that chip floating around, you might want to place it back in, since programs made for the unrom boards only have PRG-ROM data stored...

That's what I though... I think it was already introduced above, but using the controller data as a seed is probably your best bet. Generally I'd run an incrementing 8-bit counter every vblank. Then when the user presses start, that last value becomes the seed for the rors of doom...sure it gives on...

It''s fun, but I still find myself playing the VC titles more than anything else...(gee, wonder why... :lol:) I got the replacement straps too, but that's mainly because they shipped them at no cost to me. 8) I do need to order a new "sensor" bar, seeing my old one is running on an unregul...

Speaking of PRNG, anyone (attemp) Mersenne Twister? or is 2KB too much to ask?

My personal fav is the "hand-trap" rng from mario 3. They use 8 bytes (7 in version 1) or one of the bytes with 2 every now-and then, and shift right, a lot.
