| hello all, im a n00b and i aint afraid to show it. i have some general questions and though i have a hunch similar ones have prob been asked and answered before i cant seem to find a search for the forums, i figured id give it a shot here. so i am trying to hack an nes cart, not just the rom, but i would like to be able to actually have a functioning cart in the end. first of all, from what ive gathered so far, i will need the following: 1. an eprom programmer 2. some eproms 3. and a low profile socket for ease of taking chips in/out, should i get this one or this one am i right about those? now, i guess im very unsure about the whole process, that is, how i get the asm onto my computer, etc. can i use emulator ROMs to get the code? using a tracer or something like that. then, i am guessing once i get it on the computer, i can just write it onto the chip using the utils the programmer comes with, right? again, sorry if the questions sound st00pid, but im new to this. thanks for any help you can give. cheers |

| Well I actually first went to nesdev and asked them about this stuff but they all sent me here. So the big question i guess is how i go about getting the code off the cart, can anyone give me a firm answer on this? also, ive heard that certain carts are much harder because of stuff like mappers, etc. im hoping to do megaman 2/metroid/space invaders, anyone have opionions on which of these would be best? and does anyone know the difference between those two sockets? thx again |

| Hey as I am quite the n00b, this question may be oversimplified, but Ive been messing with rom hacking recently and ive been looking a lot at cory arcangels stuff. hes released his source so i think its a valuable tool for learning. i noticed that he took out the character data from smb to use in his hack, which he did by taking the lower 8k from the ROM, the question is when can you or cant you do this? I want to do a hack of megaman 1, but it uses mapper#2, which ive seen described as 128k PRG / 0k CHR. Now, I have to admit, i dont really get how the CHR could be 0k in the first place (does that mean the CHR chip is literally blank) but the thing is is it still possible to extract the CHR data from MM? its not the bottom 8k (right?) but is there another way? thanks so much for any help |

| so in other words the graphics are just littered throughout the whole thing? what would be the best way to go about extracting them, so that i could consolidate them into a single CHR rom (obviously id have to lose some of em, but its for a hack anyway)? |
