Whoa :shock: talk about a show of technical prowess. Very nice. Actually, lately I've been having a wild itch for building a YM synth, I've seen posts here and there with schematics, but are these completed? I have the software programming knowledge but my electronic engineering skills are at a very...

Thank you for the clarity, I never was very sure about the best way to do this. I meant to test the wait times on hardware but wasn't sure of a good reliable method for doing so. I'm still open to doing so and posting results if someone has any accessible ideas.

Wouldn't that mean you'd need about 18 z80 nop instructions then? Why does this sound like too many...

I've been puzzled over the math involved in determining the number of cycles to wait in between register writes. The number is 24 internal cycles * 6 = 144 68000 cycles? If a 68k nop is 4 cycles, does that mean it would take 36 68k nop's in between writes? I swear that doesn't sound right, that seem...

Thanks a ton. It's amazing how easy it is for stuff to disappear from the internet. Well anyways, this should come in handy when I get to adding 32x support for my tracker.
Thanks again friend

It seems like all the links I found through google are dead and it'd be nice to be able to have an 32x assembler for when the time comes.

Flashback is a childhood classic for me. Were you guys going to attempt the fluid animation style that Flashback had?

Sounds like a cool project.

Hey I thought you said you weren't an artist.

What is this you're working on out of curiousity?

After lots of great progress on the old tracker I lost all of my source code. Although it was pretty functional there were quite a few problems. Anyways I learned many great things the first time around and now I would like to start fresh with a solid foundation, with more efficient coding principle...

It's time for me to make a contribution to the forum. About the assembler... The hugest plus is that you can use it to assemble 68k and z80 code in one go WITHOUT needing to include pre assembed binaries. I tested this with success. The preprocessor seems to be compatible with multiple different typ...

Haha it would still only be able to express one and only one note then, but at 697 different locations. Wishful thinking got the best of me. Well. I suppose one note per byte is the best it will be, which is still better than the original 2 bytes. Thanks for setting me straight on that one, I don't ...

If it weren't for Spritesmind I would've never gotten as far as I did on my 68k asm genesis music sequencer. I lost the source code and sure people had their rude moments but I was nagging a bit too, that doesn't mean spritesmind is a failure. I'm going to start my music sequencer over again from sc...

No I remember you asking how to get the song to stop properly when pausing. I wasn't sure if you ever got that figured out but it was last year so I don't blame you for not remembering.

I guess that real decompression can be done as you will have very few data to unpack at each frame, at max i guess you can send 500 bytes to the YM2612 and that is already a lot. Of course i don't consider the PCM data. Still i'm wondering if you are not too optimist with your compression schem.. (...

Wait. So it couldn't be done by including pre assembled .asm code? Would I have trouble mixing asm and C using SGDK? Of course you can do it by using assembly code, it's just that you cannot force C code to use registers when calling functions. Hey Stef :D Interesting... well it's not something I'v...
