ROM Patcher is a ROM/binary file patcher that supports IPS, IPS32, UPS, BPS, PPF, XDELTA1, XDELTA3, DPS, ASM, XPC, DLDI, APS (both GBA and N64), and BSDIFF patch types. It also supports decompressing ECM files via unecm. Simply choose a file to patch, the patch itself, and optionally an output file name and tap "Patch". Best of all, the app is completely free with no limitations. Can be used with video game ROMs/ISOs (NOT for apps/F2P games) to add new levels, translations, and more, or on any other files that a patch exists for. No ROMs, ISOs or patches are included. All requests for ROMs and ISOs will be ignored. This app uses components from MultiPatch for Mac which is licensed under GPL. The source is available if desired. This app is the first open source ROM patcher to support IPS32 patches.

Q: How do I hack <Insert Game Name Here>?
A: This app is not intended to modify apps, only ROMs or ISOs. You cannot 'hack' CoC or Shadow Fight 2 unless you provide the patch.
Q: Pokemon Glazed
A: Check the "Ignore checksum" checkbox
Q: I cannot install/update the app
A: This is an issue with Google Play of your device at the moment, not this app
Q: The patch doesn't work
A: Make sure the ROM is correct, untrimmed, and all files are unzipped/unrar'd/un7z'd
Q: The patched ROM doesn't work in _______
A: Contact the author of that app, not me. There is no guarantee the patched ROM will work with any third party apps. ROM Patcher only applies a patch to a file. If you provide an incorrect ROM or patch, any errors that may occur are not the fault of ROM Patcher.
Q: There is no file extension!
A: If you cannot rename a file, you probably shouldn't be using this app
Q: My ROM/patch wont show up
A: Ensure you know where the files actually are. Also, make sure the patch file extension matches one of the ones listed above and you are not trying to patch a patch file.
