To inject the rom of Zelda I inject it at the end of the file and edited the pointers and the rom type

This is the file after editing the pointers.

So you deleted the original rom pasted in the Injected at the End cange the value to 01 for a 1mb file

What about the pointers? how do they work? that part is very vague (didnt help also with massive screenshots)


oh NVM get it now

To be honest, I'm struggling in the process to inject into anything other than GBA - it uses a simple converter tool to convert ROMs and with little else work. Why is it so hard to inject into NES/GBC?

I would love it if someone was able to make a step by step tutorial, or an easy program, to decrypt, inject, and install injected NES/GBC and SNES games.

One other thing I'm missing, how the heck do I edit a 3D banner? I'm so sick of people using stretched boxart as the banner, and I'd much rather have either a non stretched version of the game's logo, or the original banner style (NES with TV, or Game Boy) with the new game.

Sorry the offset of the rom type is wrong in my old image (i tried a lot of combinations before find the correct) the correct is the value of the offset 33, 08 if for 512KB (4Mb) 16 for 1MB etc.

Edit: Super Metroid works to.

guess it would be a correct though i thrpught you meant rom size

but DKC is a 32mb rom so i guess it would be 64 in offset 33
