SKS Super Kannagi Sound , new driver for SNES

Post by Kannagi » Wed Sep 18, 2019 4:59 am

Hello, I never finished a SNES game because it was missing a sound driver that corresponded to me and so I started to make one, it is not finished, but I think it will be soon ;)
It is therefore a driver that converts the main formats .mod / .xm / .it /..s3m into a custom format

Zelda and SoM are in .xm
Zelda GB and thunderforce are in .mod
Castlevania of .s3m
World of Demon of .it

For the sizes we have:
Zelda SNES: 4.4 KB
SoM: 8.6 KB
Zelda GB: 0.8 KB
Thunder Force: 3.8 KB
Castlevania: 2.7 KB
WoD: 2.7 KB

So I think we can have a complete OST for less than 300 kb (for 40 music)
My driver allows 50kb Sample (shared for music and SFX) , default is 16 KB for music and 34 for SFX
10kb max for the track , and 4 kb for the rest (driver code, RAM, SampleDir)
I also coded my own transfets so we have 24 kb/s.

I just have a problem with the .it, I can not decompress Sample :/
(L / R to change music).

Is the GB zelda speed ok? It sounds too fast.

I 'am impressed by the size of your music files .
Keep the .it format for later, have support for .mod and .xm is already great IMO :wink:

Thank you TOUKO ;)

For zelda GB, I don't know, but the main concern is that for the moment, I do not use effect.
I just read the "effect" F / D / B (so F to change the tempo / BPM, D / B to jump into another pattern).
So I'll tell you that when I put the main effects, it will be easier to compare ;)

Well done.

Could it reach more than 24KB/s for more quality samples?.

I didn't really understand your question ^^'
This is the ROM-> SPC transfer speed for tracks, samples and SFX
And this can not really make a streaming, it takes a lot of processor time (24 kb/s = 100% CPU )
