oh yeah, i actually remember reading that information somewhere. dur.

well i think that takes care of most of my questions for now. i think this little experiment is nearing its end. (next: dumping an n64 cart?)

thanks to all those who helped out, i appreciate it

well. i have been messing with it for some hours, and i finally got the bankswitching to work. but i dont fully understand WHY it works. it actually didnt work at all when i had the CE line pulled down permanently. so i connected it to a pin on my uC instead, so i could mess with it to see what happ...

ok. so to bankswitch with this mapper, its my understanding that i have to write to an address between 0x8000 and 0xFFFF, with the last byte specifying the action. so to get to PRG bank 0, i would write to 0x8000, and to get to PRG bank 1 i would write to 0x8010. is this correct? in that case, how d...

indeed tepples, i had that idea. but i had these shift regs lying around and i cant afford to put in a digikey order right now. anyways. at less than a minute per 32k block, im not complaining.

ok, so i really feel like an idiot now. thats what i get for reusing old code i guess. or something. anyways, it comes out perfectly now. im getting about 1 kbytes / second, i dont know how that compares to a copynes. i would be curious if any could tell me. the next phase is to get mappers sorted o...

omg! you are totally right. they arent even hooked up 'backwards', because thats how i wanted to put them. my shift register subroutine just pushes them out backwards.

ill change it around and report back

im starting at 0x00...0010 in the reference ROM file i have, it is my understanding that that is where PRG data starts.

im just viewing it in a hex viewer.

i busted open a SMB w/ duck hunt cart the other day, and it doesnt even have a pin for phi2.

dont know what it means, just thought id throw that out there.

Hello all I am a university student in computer engineering, and i am making a circuit to dump NES cartridges. why? just for fun & learning. i came into this project with absolutely no knowledge of how the NES works, but through much time spent reading the wonderful articles on your sister site,...
