Just a q relating to one stumbling block I feel for my desire to convert my c64-sf2-reu port to mega65.
Presently, my makefile just prepares a data.reu file (containing sprites, music) which vice can drop straight into reu memory.
Not sure which path to take to get something similar for mega65.
Will I need to instead drop the data.reu file onto a .d81 image and write a routine to copy it into upper memory?
Any existing examples of similar things I could take a peek at?
