How can you edit the scores int he nokia 3310 games?

With a hex editor.

Get a reasonably high score, backup the EEPROM section only (3D0000 to 400000 ), then open up a hex editor. Convert your score into HEX, then search for it. For the maximum score, try FFFF , or 9999 (one is for Snake II, the other is for Space Impact, can't remember which :()

Then just reflash it, there are no checksums in the EEPROM, but i think you need to calculate the FAID.

cool, sounds complicated tho
