[Reaper Man]

Okay, so I've looked at the LoZ rom and I can't help but notice that there are what looks to be RLE encoded graphics tiles, but I could be wrong.  Is there a complete map of where the graphics are in this game?  I kinda need to know for my rom corruption project.

This could be of help: http://www.romhacking.net/docs/365/

sounds great, cept for the fact that said document is for A Link to the Past, and not for the original NES game.

Yeah I saw that, but the ROM map looks a bit incomplete.

I'm probably going to open the ROM up again and compare addresses and see if the locations I'm wondering about are defined in the map.

What still puzzles me is what the hell is the data located around 0x1C000?  Anyone know?

The game uses chr-ram, so they aren't exactly aligned in rom. Offset them by a few bytes here or there and they should show up correctly.

The data starting at 0x1C000 are DMC samples. The first one is used for the sword sound fx. I'm not sure where the samples end or what chunk of data is for what sound.

Here's an incomplete dissassembly if it will be of any help.

Ah, so that's what it is.  I guess I could corrupt that too, but it probably won't do too much.

As for the disassembly, I won't need it for what I'm doing.  Thanks anyway.
