About this app

UniPatcher allows you to apply patches to game ROMs.

What is a patch?
A file with the modified data of the game. For example, a game translated from Japanese to English. You download the patch containing the translation. It must be applied to the Japanese version to make an English version of it.

This program will not help you hack native Android games, it was created for the old console games (SNES, PS1, GBA, N64, SMD\Genesis etc.)

Features:
* Supported formats of patches: IPS, IPS32, UPS, BPS, APS (GBA), APS (N64), PPF, DPS, EBP, XDelta3
* Create XDelta patches
* Fix the checksum in SMD\Genesis ROMs
* Remove the SMC header from SNES ROMs

How to use?
You have to select a ROM file, a patch and choose which file to save, then click on the red round button. Files are selected through the standard Files application (or through one of the file managers you have installed). The application will show a message when the file is patched. Do not close the application until the file is patched.

Very important:
If the game and patch is compressed (ZIP, RAR, 7z or other), they first need to be unzipped.

Ratings and reviews

I really like Unipatcher but when I try to patch something that's .xdelta and then save it, it has 0 bytes. I have to rename the xdelta and run it through Unipatcher which then gives an error but once I change the patch back to .xdelta it patches fine and goes from being 0 bytes to whatever the game is supposed to be. Idk if I explained it well but it's really weird. I've found a way to make it work but it would be better if I didn't have to do that every time.

I mostly use this for patching GBA and N64 hacks. 95% of the time, it works flawlessly. The other 5% of the time, it doesn't work very well at all; but this is more of an issue with the actual files than the app itself. Sometimes you just gotta use a Windows or Linux desktop PC/laptop for a tiny handful of hacks. Generally, though, anything you want to run on emulators will work fine.

I used this to patch a ROM with an XDelta3 file and it worked like a charm. If you're having trouble using this app, remember to make sure that neither the ROM nor the patch are compressed (like in a Zip folder). Also, there may be many different versions of a game even for the same system, some of which are not compatible with the patch for that specific ROM, so make sure to read the instructions that come with each patch carefully and take note of words like "Rev" or "PRG".
