Basic flashing operatoins working. Still need to do some tests and erasing before flashing.
Need to verify page programmed successfully as it currently just continues even if unable to flash proper data. Need to make write page utilize variables for bank address based on mapper and/or memory as currently doesn't flash CHR-ROM due to $5555 $2AAA being above address space of CHR-ROM
