Are you new to 6502, NES, or even programming in general? Post any of your questions here. Remember - the only dumb question is the question that remains unasked.
What would be the most suitable EPROM for use on a HVC-RROM reproduction?
The CHR pinout is extremely odd, would I absolutely have to resort to having to rewire it, if so, are there any good examples on what exactly to do? Or should I just push it aside and grab a much simpler NROM board instead. Thanks!
There is plenty of room inside the shell isn't there? If I were you, I would get a DIP socket and solder wires from it to the PCB. This has the advantage of being a removable EPROM, so you can reprogram it at a later date.
To fit a DIP socket you would usually have to cut a whole in the cartridge shell, and even when doing that there's only just enough space for it. Unless maybe if you have a very low-profile socket or something.
If you put a DIP socket into the original PCB, it will not fit into the shell, that is correct. But, if you put the socket free-floating in the empty space in the shell, connected with wires, it does fit.

Thanks for the advice, didn't think of that! I don't mind cutting a hole in the shell to take out and reflash the eproms as I'm just making it as a fun project.
