OK so far I have replaced the PRG rom in "Crysalis" with the 256k flashrom "Pm29F002T-12PC" witch is very simmaler to a 29F020
the onley pins I left unconnected is WE# and OE# everything else is connected to its maching place on the board
I have cut out the CHR rom but have yet to desoder the pins from the rom witch was on there
as a test I have tryed loading a rom image of the japanise game "shaffen fight" by eraceing the 16bite header leaveing me with an image just the right size
due to the fact I an unwilling to risk my real nes till I get it working I am useing a crappy noac famiclone called "Game Player" when I try to load the cart all I get is black and afterward it wont run any cart for a wile then it starts working again
