Heya guys, I'm working on fixing a gameboy ROM now, so I figured to show how to know if a pirate is dumpable or not!
You will need:
An undumped pirate
A cheat cart
(and a dumper if you're actually gonna dump yourself)
~
Step 1: Put the cart in the cheat device
Step 2: Put it in a gameboy (uh lol no shit Sherlock!)
Step 3: Try it with the cheat switch turning 'OFF'. It should work.
Step 4: Now try with cheats 'ON'. If it works, then all to fix the game is in the header (or the 4mb trick, then if not, just switching around banks)!
If it doesn't work however, then fixing it is a pain, meaning you have to edit the damn code for it to work.
Hope this helps, taizou, BigFred and everyone else who does this!
Warning: it's only to see the strength of the protection.
