YES
IT IS POSSIBLE
WE DID IT
Now we're working on loop and making stereo. Oh, and injecting files bigger than the original.
Cause some of the AST files are >15MB. Just like BRSTM. But cooler.
Made with genius tool - ast Converter 2 from Kuribo. Rom repacked with GC-Tool, but I think I found alternative - GCRepacker 1.0.
Have fun! Anyone interested in helping us?

Please, Dirb, you're the only one who can improve MKDS hacking, can you add support for NCER cells? These cells are used to display images in cells made out of NCGR tileset, specification can be probably found on Tinke website. Thank you.
And btw: I'm posting it here, since the "Post thread" button under Editor developement is broken

Works with almost EVERY game.

STFU YOU'LL SPOIL IT
But yes, we managed to fix it, but we don't wanna release until tomorrow to be sure.
So tomorrow at 20:00, stay tuned for music hack better than in Super Smash Bros Brawl.

IN IN IN IN
So what, are we resurrecting SYStEM? Don't let our hopes down, please.
I'll do what I can to keep it alive.
