The only visible changes are in the NVRAM, where the $0000 offset hasn't the JMP $C210 instruction
injected at the start...
Maybe some scrambled instructions on the fatidic 'mexican' Rockwell R65C02 (like Magic Card II)??...
Maybe mnemonic 93 is AXA (ab),Y (93 ab) instead of NOP (as seen in some sources)??...
Tooo much obscure/darkness here
So... No idea what's wrong here.
If someone could figure a possible transform, please let me know.
