Nope! CVSD works by comparing the current wave value with a derived sample value. If the wave is larger, it outputs a 1 and adds a delta to the derived sample value; if it's smaller, it outputs a 0 and subtracts a delta from the derived sample value. The key to improving the sound quality is how yo...

I meet the problem on ealier gens version, as i used that mickey level a lot to test my emulator i quickly fixed it out though. i m not sure it a simple sprite mask bug, but for sure it s an emulator bug, it doesn t happen on real hardware.

Re: Z80 driver - 4 channels player with volume control.

anyway we can have a sort of very simple MOD player i guess ;) Yes, but it will barely usable because of many drawbacks: - It will require to write new music for it (taking all limitations in account) - To compensate lack of pitch effects longer samples will be needed (takes more memory itself, and...

Re: Z80 driver - 4 channels player with volume control.

Link does not work, empty page. we can build samples at all needed rates No pitch effects then (arpeggio, slides, portamento, vibrato), or you'll need very many samples. Does MOD support all that ?? well i suppose i've been optimist :p anyway we can have a sort of very simple MOD player i guess ;)

Z80 driver - 4 channels player with volume control.

Lately i had to rewrite my 4ch player Z80 driver as i lost some sources :-/ Wasn't that bad after all as i was capable to improve it and get more "free time" than my first shoot. I have about 48 free slots (/256), a bit less than 20% of Z80 time which is enough to handle some YM2612 or/and PSG comma...

Afaik the drivers aren't included as C files, only the MVST driver is in this format because i don't have the original source :-/ Drivers are provided...

I lost my evening on this one yesterday !!!! ;) hop, ba...
