ROM Patcher

ROM Patcher is a focused Android utility for applying modification files to game ROMs and other binary images. It supports widely used patch formats such as IPS, IPS32, UPS, BPS, and PPF, along with several additional formats that show up in ROM hacking and translation projects.

It is best suited for emulator fans and ROM modders who want a straightforward way to create a patched copy of a ROM or disc image on an Android device, without the app bundling any ROMs, ISOs, or patches.

Format coverage that fits real-world patching

ROM Patcher’s biggest strength is its broad compatibility. Beyond the common patch types, it also supports formats like APS (including GBA APS patches), DLDI, SNES ASM, Asar .asm, DPS, and XPC files (with “ask” not supported). It also includes support related to XDELTA1, with later updates calling out xdelta3-related fixes.

A simple, selection-based workflow

The app keeps the process direct: you choose the file you want to patch, select the patch file, optionally set an output name, and run the patch. That approach makes ROM Patcher easy to pick up, even if you only patch occasionally.

File browsing touches that reduce friction

ROM Patcher includes a file browser with a fast scrollbar, and it can display files that do not have an extension when you are choosing what to patch. These are small additions, but they help when you are dealing with mixed folders and older dumps that are not consistently named.

Practical tools for picky patches

When patching goes wrong, ROM Patcher provides an “Ignore checksum” option and offers format-specific guidance. It can also decompress ECM files using unecm, which is useful when your source material is packaged in that format.

Scope and availability

ROM Patcher is aimed at patching ROMs and ISOs through supplied patch files, and it does not target Android app modification. It is also currently not available on Google Play.
