ROM Hack [OR/AS] Pokemon- How to modify files?

[pepsikill2011]

Hey

I was about to delete some file of my computer when i saw some old hackrom and said to myself "Hey, why not create your own? "

So i download the stuff but i have a main probleme

I work with a already hack rom (Pokemon rising and sinking) but there are in .cia and i have absolutely no idea of what to do, i have Exefs and "a" file but i don't know how repack them into the cia or unpack a .cia :/

Decryting / Extracting / Rebuilding guides: Asia81's guide on how to decrypt extract and rebuild a cia // ihaveamac's 3DS-Tools guid (recommended because more up2date)

X/Y romfs 'a' folder content reference paste

ORAS romfs 'a' folder contet reference paste


Other than that I recommend having

- Microsoft Visual Studio Community 2015 -> for building source code of aforementioned tools
- Decrypt9WIP or Hourglass9 by d0k3 for decrypting the game and generating xorpads
- 3DSBuilder -> to rebuild roms as .3ds (included in Asia81's guide)
- ctrtool / makerom / bannertool / 3dstools -> also for rebuilding/extracting etc. Included in ihaveamac's tutorial
- Adobe Photoshop for texture editing
- no over ambition. Model editing especially is not something you learn in 5 minutes and a lot of hours go into creating a romhack. Have dedication, but don't put too much on your plate.
