Need help making my nes roms the right size to burn on a epr
by on (#46845)
California Raisins - The Grape Escape when I remove the header from the rom in properties says it is still 128 KB size (131,077 bytes) size on disk says 132 KB (135,168 bytes) is their still something else I have to remove
or is this the right size because http://nintendoallstars.w.interia.pl/romlab/prepare.htm at the bottom of the page it says that a 128kb should be 131072 any help would be great :lol:

131077 means there are five extra bytes somewhere. How many bytes were there before you removed the header, and how many bytes of header did you remove?

128 KB (131,088 bytes) I removed the first 16 bytes

Your hex editor appears to have been set up so that the first row is only 11 bytes. Do the next four rows start at positions 00000B, 000016, 000021, and 00002C?

yes the next 4 rolls say 00000b 000016 000021 00002c :lol:

Then you only deleted the 11 bytes in the first row. You need to delete five more bytes from the beginning of the file.

Check the board's mirroring. What it calls H and V is the opposite of what the header names it.
