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.

5 stars hands down! This is much more fluid and stable-looking than another patcher I tried. Also, if anyone is having problems, consider that your original ROM file may be at fault. I have a SMW rom that I've played perfectly fine for years, but no matter what I tried I could not get the patch to work with it. I tried downloading a different ROM of the same game and it combines with the patch perfectly.
