Re: 216 colors with one palette
Not dithering, but horizontal striping. Same difference. It's just a different form of dithering. On my system, I don't see rainbow artifacting, maybe I would in larger swaths of colors, but some of the colors do not match exactly what I see on the emulator, which is not a surprise. Luma signal is ...

Actually i searched a solution for that : use DMA and require only a single plan with a single buffer, all these and still allow a fast software filling code (12 cycles per move.l instruction) but i did not found any solution :-/ I can give you a hint: you need two address registers. :) About the m...

looking for help with homebrew game
See here: http://pcedev.wordpress.com/2014/08/21/game-2014/ Basically, I'm looking for pixels artists for sprites, BG tiles, map/area layout artists, portait/cinema artists, and chiptune musicians. So that's four different graphic artist positions (doesn't need to be filled all by the same person). ...

Upsampling, on the other hand, is the process of taking a piece of low sample rate source material and "filling in the gaps" by interpolating between the available samples. From the descriptions I've read of over-sampling, this is exactly what it is. N number of times the output of the source input...

Thanks! I knew that there was an interlaced mode, I just heard some people saying that the Mega Drive wasn't capable of any progressive scan at all. Seems like they were wrong :D They probably mean HD TV progressive modes, like 720x480p, or 1280x720p. The progressive mode that virtually all old con...

Bizhawk How have I never heard about this? I'd love to hear more info about this CDL thing. It's a very simple idea and execution. The emulator creates a large Byte array, that's equal to the size of the rom. Each byte in the array corresponds to a byte in the rom address. So it's a map of the rom....

If you're a hacker or wanting to convert a game back into source (disassembly), CDL support is a MUST. I've used it in fceux to create complete ASM listing of two games. Bizhawk doesn't support Genesis yet (that I've seen), but recently they added a great CDL function to the emulator. The CDL marks ...

The PC-Engine's VCE chip (which houses the color ram and outputs composite and rgb video), bit packs the 9bit RGB and uses that to index a 512 entry LUT. You can do this approach in software as well, but the problem is converting back. You still have to convert back to R/G/B. 9bit might be enough fo...

PCE has 9bit RGB very similar to the Genesis. I've done palette fade routines on it, but it's usually just subtract 1 from the R/G/B element and check for clipping. It's works, but yeah - it's not exactly the natural-est of looking fade in/out. Other than precalc palettes (which some games use). You...

4 bit samples use less space than the 7 or 6 bit samples, I'd also hope to save some reasonable amount of cpu power for things such as sound effects and voices. Assuming you nibble pack the 4bit samples to save space, you're gonna eat up more processor time separating those nibbles than just using ...
