Hello, any idea of what to send using this
https://github.com/Stephane-D/SGDK/blob ... c/ym2612.h to output some sounds ?
Is there some documentation somewhere ?

There is a test program at the end of this documentation which should output a single piano note sound :

But honestly doing sound from YM2612 by hand like that is really root... Normally you should use a kind of sound driver to do that

Many thanks for the good link!
Yes, I use a microbrute with patch inputs, so I could use megadrive to do somethings. Root but awesome

Whats the best way to hilight text drawn with VDP_drawText ?
May I draw it over with another color using VDP_drawTextBG or what ?
Edit: ok, VDP_setTextPalette, sorry.

Ok got this :

Arrows to navigate, A/B to upper/lower things...
A bit bugged, and too much things, I think I'll lower features just to make some tone generator.
Edit: I exposed most of the doc, only missing are the special channels 3 features, and volumes/envelopes are broken now it seams...

Ok, it works !
Here is the YM2612 controller :
http://downloads.kstorm.org/YM2612.bin and
https://github.com/skarab/megadrive-YM2612
The play modes (the thing on the left of the sequencers) are : 0 nothing, 1 play sequence, 2 tone generator (play always with 0 decay release in ADSR)
