Help with "sketch_hack_write" in MC-G01 Maintenance Cartridge hack

[nickport2024]

I’m trying to use the sketch “sketch_hack_write” to upload a ROM to the MC-G01 chip, but when compiling the sketch, keep getting the error message:

"Programming\sketch_hack_write\sketch_hack_write.ino:97:35: error: 'my_rom1' was not declared in this scope
buf[j]=pgm_read_byte_near(my_rom1+i*buf_size +j); //!!!!!!!!switch from my_rom1 and my_rom2 if need ^

exit status 1

Compilation error: 'my_rom1' was not declared in this scope"

If I delete the subroutine below the line 87 “//more efficient write” step, the program runs, but the results don’t match the input ROM.

Any help with this sketch?

Thanks,

Hi, here is a friendly reminder:

Yes, by default the sketch_hack_write cannot compile. Since it misses the rom:

The wiki says clearly, you need to copy the output from sketch_hack_read and copy to sketch_hack_write.
