Nice project! Does this also use hacks around the PLA like EasyFlash? Why not use pages of 8 / 16Ks too? I had once a simpler ram extension idea employing the same concept in below old project which was published in the Transactor. (But of course with a bigger 512K or 1MB sram) http://ar.c64.org/rrwiki/images/5/57/The_Transactor_Vol07_04_1987_Jan_A_C64_Cartridge_without_Eproms.pdf Sure this solution throws away the existing ram but it's easy to bank in a whole 8k or 16k segment at once. It would be nifty to have some external storage mechanism in the cart too. It would be really cumbersome to load content into this additional ram from the disk drive.
