ROM Hack [Release] DS ROM Patcher

[evandixon]

Normaly, distributing ROM hacks for NDS ROMs involves an XDelta patch applied to the entire ROM. 3DS hacks usually involves tedious ROM extraction and file replacement. Patches applied to the ROM as a whole do not support multiple regions of games, and tedious ROM extraction and file replacement is a chore. DS ROM Patcher aims to fix that: a single easily-distributable zip file contains everything that's needed to apply a hack to a ROM. The supported input and output formats are the same as in my .Net 3DS Toolkit: 3DS, CIA, Hans, and Luma Layered FS.

Instructions for creating and applying hacks can be found at the GitHub Readme page.

Requires the .Net Framework 4.6.2

Does this mean I Can convert a .nds -File into a CIA ?

No, it's an alternative to xdelta.

So does this work with .NDS ROMs too, or just 3DS?

I think it's targeted at NDS, while also supporting 3DS

Both are fully supported. Because 3DS ROMs are more complicated, it's more useful for the 3DS, but it can still apply edits to NDS ROMs from different regions depending on the exact changes and the setup.

I am a bit confused ???
What does the Programm ? (I thought it would patch the .nds so u are able to load "cartridge backups" with TWLoader)
Now I think it's just to apply mods to a .nds file but why do u publish this in the 3ds Forum and not in the DSi-Forum ?

It allows ROM hacks for NDS and 3DS ROMs to be easily distributed in a single zip file, which can easily apply the hacks to a clean ROM.

So i can patch my CIA (ex.NSMB2) with the Halloween Mod ?
and the I would get a Romfs or a CIA ???

If someone made a modpack to apply the Halloween Mod (see the readme for terminology and usage), then the resulting zip file can apply the patch to a decrypted NSMB2 ROM, giving you a CIA or putting the files required to use HANS on your SD, whichever you pick.
