I guess, it is simpler to use 4-bit PCM than DPCM or ADPCM, I can't imagine getting sampling rate over 8KHz decoding DPCM/ADPCM with z80. All of these formats cause some noise, and it ruins the sound when sampling rate is low but 4-bit PCM does not need to be decoded so sampling rate can be as high ...

It will use similiar techniques found in Sonic with my own quirks. For sprites, I probably update sprite patterns in VRAM or do like I did with GBMD, load all graphics into VRAM and don't do any updates during the game. I don't actually know how much tiles I would need for one stage, if there's not ...

New game in developement... CA the Meowian
After I finish GBMD (it needs some work) I'm going to write a action game which is pretty much like Contra or Metal Slug (NeoGeo). Main character: http://www.hot.ee/tmeeco/CA.PNG I made this decision yesterday, originally I planned to make a PC version in QB (or FB) but then again, MD is little easi...

oops, there were some inaccuracies in my code (well, I wrote it by heart and with winter gloves(don't ask why :wink: )), I fixed the code. As far as i know, DPCM is just delta and ADPCM is delta which can change a little. DPCM would be much simpler to decode than ADPCM. still, you need to be a wizar...

I might be incorrect: * VDP reads data from the scrolldata * then reads graphics according to data from scrolldata * and then adds displacement (amount of scroll) to the graphics * and displays the stuff that fits the screen And the last result is: scrolldata remains unchanged I hope it is not too c...
