What's the most recent version of this? (i.e. I need an official document as all the ones I find contradict one another.)
Would it be fair to say the following?
1. The first four characters must be 'NES' followed by $1A
2. The PRG bank can never equal $00 or be more than $32
3. The CHR bank can never be more than $64
4. Byte 6 can qual anything
5. The lower bits of Byte 7 must be zero
6. The other bytes must all be zeroes
The reason why I have WedNESday reject ROM's that have junk at certain places is to promote the use of clean images (none of that Diskdude! junk here).
