Thanks! Didn't know about radico8. That looks awesome!
Unfortunately it appears that radico8 would not support my cart as it is. Took a peek into the codes and it seems to be only loading song/sfx data from the dedicated cart memory area, whereas my song data is actually in the code and dynamically loaded to the sfx/song mem. Maybe I could do a "radio edit" for some songs, meaning a cart with that song loaded in place... Or maybe I could patch my cart to have one of the songs in the dedicated mem area to be able to submit at least that for the radio play... So, if I were to pick a single song for radio play, what would it be?
