- If your program uses any of the ROM routines then it would be a good
- guess to put $37 into $01 (that is location $0001 in the 64 memory).
- If you're not quite sure what this is all about just stick with $37
- and get a memory map of the 64 and read it.
-
- Most of the programs I'm crunching have $01 set in the code if it is
- needed and the code that sets it is in 'regular' memory (ie: memory
- that is not overlayed with ROM).
-
- The whole point of $01 is that it controls which portions of memory
- have ROM or RAM in them, in fact you can use $01 to turn off the
- video registers and get to the RAM underneath them. Sometimes you
- want to do this, most of the time you don't.
