fair enough, just thought that these would be interesting to look at since I didn't know y'all had it all figured out already - especially the FM synth replacement, as a mere outsider I would have thought there was no progress, especially since the thread about it hadn't been updated in a while. Guy...

note for admins: can you tell me if this breaks rule 3.C? I hope not, not the least because the former is meant to be DIY-only and the latter is very likely to remain on the drawing board. So, while idling around on the mastodons, I found 2 interesting projects that seem to be in effect forks of the...

Here are 2 ideas I had, lumped together because they are both related to rendering. Tile Mode Opacity Toggle: Uses bit 7 of the layers HSCROLL_H (or some other unused per-layer bit), if set, color 0 is not special-cased for palette index shifting, so if Palette offset is not 0, the first color will ...

After some thinking... yea no. To keep up with a single OPL3 will require calculating an operator in 8 cycles or less - good luck doing that with a DSP that isn't more expensive than an FPGA solution... unless you can get the DSP running at 6x input clock speed? After all, most DSPs, even cheap ones...

Now, I know this probably won't fit in the small amount of FPGA left in the VERA, just throwing out ideas that might be viable with sufficient effort for a future revision that might have more space for logic. 1) XORed triangle, basically what tildearrow's [em]tildearrow sound unit[/em] does for wav...

Sorry for committing thread necromancy, but i have a question, would a dedicated DSP chip (because those still exist for some reason) be cheaper than an FPGA large enough to hold an OPM emulation? If so, I wonder if you could program a DSP chip so it can do "frequency" (read: phase) modula...
