How are you doing? I'm wondering whether there's any progress with porting SDL2 to MorphOS, I'd love to see new MilkyTracker release someday. Don't feel any pressure, I'm far from that, just asking.
I am also waiting for SDL2/MOS. SDL 1.2.x is deprecated and only old projects use this version. SDL 2.x would help in create/port many of projects.
Maybe bounty? :) I would donate the bounty if someone continued the port.
