It is not bad to have a separate thread for that so we can find it easily. Also the demo you posted did not worked (at least for me) where Chilly Willy ones does which may explain why people has now more interest about the method :) The original topic you are talking about is this one ? I had my bi...

First, the only thing from your demo is the loop that sets up the dma, and even that had to be rewritten for GAS syntax. Second, from what's been said and the comments, this is about the only way to get the timing, which means that whole loop is a FUNCTIONAL dependency, and thus not eligible for co...

Let me get this straight, I posted the source to my implementation only to have some person reuse the code even if the readme kinda forbids it and in turn bash my proof of concept demo and accept 2 pages of praise in return...? nice going, spritesmind I know, I might sound like being an asshole, but...

ALSO About the guy's distorted head etc., There is certain parts of every line that are twice as wide, as in double "pixels", which is small lag induced by refresh cycles. No writes occur, so the DMA doesn't advance, hence "double pixels" occuring. Hardware issue, not image issue. Well, it doesn't ...

Neat ! As you said i really wonder why this had never been used for Sega CD FMV, maybe simply because no one though about it :p The sub CPU could decompress and prepare the 192x224 9 bits (word) buffer then send it to main CPU in word ram at VBlank time. Also we can use border to extends the vertic...

Re: Direct Color Demo using DMA
Okay, so what I originally invisioned are static screens and parts. You can blank the display mid-screen, use the top portion of the screen for some kind of other thing like a scroller or something, then have a high color bitmap in the other. As for the suckey image, well, we just wanted an image wi...

After converting the song with xm2esf, how would it be imported/compiled into my SGDK-based project? How do I refer to the data so I can pass it to Echo's functions? Before using xm2esf, you must gather all samples, psg envelopes and FM instruments you intend to use, and build an instrument pointer...

I make an XM file with fixed channel layout and try to make something that sounds good. if it does sound to my liking, i start making the MD version of it with xm2esf. It's quite simple.

I made the entire game's soundtrack like that.

- does it support whatever TFM and VGM trackers output? Not at this time, because the two formats are so different. My tool "xm2esf" takes any XM tracker output though, and converts it quite accurately. - do sound effects play on the genesis sound chip or the mastersystem sound chip? both? Both! All...

Yeah, emulators aren't designed to handle this... neither Gens/GS nor Fusion handle it correctly. It works great on my CDX - very stable. Any source on this? I'd like to do some experimenting with it. :D as soon as I can be bothered to boot up my old barebone again :D (I wrote the code on a tiny at...
