Anyone here used NesderDC SE for the Dreamcast? It's nice, you can add pictures, NSF, game genie codes, FAQs, and manuals for all the games. I've found though that it's database doesn't have listings for all the games that I have selected (nor the manuals and other extras). Or perhaps it does but only for different versions of the game.
I'm currently modifying it's database but cannot figure out how to produce a CRC of the .nes files. The first thing I did was use a CRC-32 calculator on one game that was known to work but the result of a didn't match what was in the database. Then I learned that it is standard in the NES community to only calculate after the first 20 bytes and so I made a copy and stripped out the first 20 bytes with a hex editor. Unfortunately the CRC result still differs from what is in the database so I'm sure I'm still getting something wrong. I am having difficulty finding any hard data on this, how do I correctly calculate the CRC-32 of a .nes file?
