For example, I was expecting my Mega Man IV dump to have a CRC32 of $18A2E74F, but I got $2bc67aa8. Gameplay and graphics are perfectly fine, no glitches. Another example is Gradius II, a pirate cart where you can select weapons with B+Select. Tried a lot of times, the same result. The game works, but the graphics are all corrupted. I can't open the cartridge case - I glued it 20 years ago, no way to deglue it... unless I break the case. No, I won't. ^_^;;
For Gradius II, these are the CRCs:
Code: Select all
Gradius II.nes, mapper 25
Program ROM: size 0x020000, crc32 0xfdc83487
Charcter ROM: size 0x020000, crc32 0x116d5e18
- I have two other carts unable to get a correct dump. A 2in1 yellow cart within Side Pocket (?) + Rockman 1. The loaded game varies with RESET. The other cart is the 600in1 (only 33 unique games on it).
