ROM Hack [Idea] 3DS Rom corrupting...?

[Ruby Gloom]

Anyone ever think of using the Vinesauce Rom corruptor with a 3ds rom? What would happen...?

It would probably fail to boot because of all the security checks... I am going to try it later!

We do have the option in the corrupter to start at certain bytes. Maybe avoiding the security checking?

Even with crypto checks patched out it would just crash. NES roms are very different from 3DS roms in the way they are coded.

Ooh I forgot about that, can't wait to try this later!

Well, here's the thing.
VRC can corrupt more than just NES roms. And more than roms themselves. They corrupt any file you want.

Yeah. You can probably corrupt the game's sprites and sound if you extract them from the romfs and still have them render/play, but corrupting the actual code would just make it crash.

I'm still going to try it.

You can probably corrupt individual files, if possible. It'd probably be funny to corrupt model files that way.

That's what I was thinking as I saw Smea's Twitter video of showing Ocarina of Time 3D with messed up Link.

I've already done this

FRICKIN HOW??!!!!?!??!

I just corrupted the Mario's bcmdl(contained in an szs) in the romfs and loaded it with HANS.

I might wanna try it out someday.

I'm gonna try this later with CorrupTool.

You can try using NTR debugger to corrupt RAM memory. Write some random data on random adresses of game's PID.
Also easy corrupting method for Majora's Mask: just open and close ntr menu. This will mess up npc textures xD
Edit: I found the screenshots I took.

Edit 2: These are results of RAM corrupting in ORAS. I somehow changed clouds into tetris blocks

Gateway released an update allowing us to write to memory of games. Should this work or no...?

I'd imagine it would.

 

[Ruby Gloom]

What would be the best addresses to write to? The ones closer to 0 or the higher ones? I'm new to this idk what i'm doing.

It's probably best start a little while after the start of the RAM dump.
If there's a RAM map available for whatever game you're RAM corrupting, then I'd suggest maybe looking at where stuff is stored, and deciding a good offset to start at that way.
there's probably not very many if any ram maps for 3ds games though, i'm just going off of what i do for rom corruption
