Thanks for the explanation!

I have to revisit my memory layout; to be honest I haven't yet designed 
how the cartridge mapping was going to work... 4KB banks is good, but I 
was planning on being able to swap in/out smaller windows within the 
upper 32KB address space. Lode Runner uses the entire lower 32KB for 
video memory, graphics data @$8000, code & game data @$C000... so I was 
thinking a 4KB window somewhere to be able to load level data - the 
original Apple II loaded this directly from disk sectors.

And EEPROM for save game data is awesome! I was going to propose a 
'standard' structure so that games from various authors could co-exist, 
like a tag/header+length for example, or maybe even a FAT-type scheme...
