I try to store file in cartridge port, i use the my test kit hardware for this (ROM4 only, 64K for for test).
I see in Junnior prommer folder 2 softwares:
install.tos for create ramdisk i choice 0 for 64K (2x27256)
i copy 2 files and 1 empty folder on ramdisk.
i launch save.prg choice the ramdisk and save file.
I programm the Flash IC (SST39SF040, i use only the first 32K):
Lower for odd and pair for High.
On my TT is see only 2 wrong files (named 5 and T).
For check i read the cartridge port in GFA at &FA0000 i have 'AB' and &FA0001 'CD'.
For me is correct.
Any people as other software solution for create the good file ?
