Can't split .nes file?

Can't split .nes file?
by on (#67544)
I'm trying to use this software: http://www.romhacking.net/utils/683/ to split castlevania which does not have a chr file, only prg. It gives this error:

also I'm going to use a 27c512 eprom, do I need to do anything special besides a bit of rewiring? Like any specific ways of burning the eprom.

27C512 is 64kB (512 kilobits), Castlevania is twice that size. It's just one ROM so there's nothing to split other than the header, you could use a hex editor to remove the first 16 bytes.

So then what eprom would I use? 27C1001?
How would I get rid of the .nes to get the prg bin file?

That will do. Keep in mind that the size of these chips are usually measured in kilobits. To convert kilobits to kilobytes you have to divide the number by 8.

ROMs that don't have CHR (like is the case with Castlevania) are just made of a 16-byte header followed by the PRG. The header is always 16 bytes, so you can just open the ROM in an hex editor and delete the first 16 bytes. Save it as a new file and check the size: Castlevania should be exactly 131072 bytes (128KBytes).

If your using windows, try my ReadNES2. It will do this easier if you don't have a text editor handy, and if there's a CHR-ROM, It will save you loads of time.


Edit the batch file and put the .nes's ROM name in there instead. It will make 2 .BIN files for you to burn to a EPROM/ROM. Even though the CHR=0, It still makes a file I think....thats something that will maybe be fixed if I ever change it again.


Anyway, here's the link, good luck! :D
