Bank switched 128K ROM header

[+acadiel]

I had to post this for atrax on FB earlier, but here you go, for anyone wanting the source code Stuart, Tursi and I made to bank switch a 128K ROM (i.e. Fred's Megamod cart with all three of his utilities). It should read well if you know assembly, if not, let Tursi or I know and we'll explain.

All the routine does is take code in certain locations of the EPROM of a certain size, copy it to a certain address in 32K, switch to the next bank when it need to continue and has run out of data (obviously the data starts after the header), and continues to the next bank as needed, then branches to >A000 to start the program.

 

Enjoy.
