Nes Freak | 584 Posted June 12, 2021 Share Posted June 12, 2021 (edited) for if the eprom dies of bit rot in your m82 USA version you can reprogram it using this. i dumped it awile back but it appears only the PAL one exist for the public. i did a rom comparison in a hex editor there only a few small differences. ver 1.0 (bad dump) two bytes are off on first line of code. the ntsc and pal version of the rom are identical just fyi https://www.dropbox.com/s/m4gv66gc4xkxz96/M82 NES (U).zip?dl=0 Edited June 26, 2021 by Nes Freak 3 3 Link to comment Share on other sites More sharing options...

This ROM you posted, on the other hand, has the "entertainment system" on screen the entire time. Do you know what the story is behind this discrepancy or is this an issue with the emulator I'm using to run this ROM? 1 Link to comment Share on other sites More sharing options...

Dr. Morbis | 2,088 Posted June 17, 2021 Share Posted June 17, 2021 Damn, I just packed it away as I won't be building my new collection room for a couple of months. But I will unpack it again one of these evenings and hook it up again to get a video... Link to comment Share on other sites More sharing options...

Nes Freak | 584 Posted June 26, 2021 Author Share Posted June 26, 2021 interesting. so i look at it again in the hex editor turn out the two missing bytes control's when the entertainment system is on screen. cause i changed the two bytes and saved it and then it work as it should. so in that has this is a bad dump. all though i think its weird those two bytes in the first line of code wernt ripped when the rest came over fine. so anyways that mean the pal version and ntsc version are identical. thanks for noticing that lol.
