This is for the CLIphobia who wanna patch but don't wanna touch the command prompt.
Each line contains what to patch (hex bytes) and how to patch (offset or bytes to be searched).
Comment lines (starting with '#') are ignored. Comment should not use ~ (tilde) since it's used for serialization of patches in URL. You can replace ~ with $HOME (in path), or %7E (in URL).
Example of patching at specified offset with hex bytes:
DEADBEEF FE E1 DE AF
ACE0FBA5E: 0xFE ED C0 DE
0xFEDD06F00D :CA FE 0xBA BE
DECAFDAD : B0 BA C0 FF EE
# BAEBEE : FE EE F1 F0
Example of searching and replacing with hex bytes:
# FA CE B0 0C =0x0F F1 CE
0xB0 0B= D0 0D 0F DE ED
Patches are read from URL hash at start-up, such as #{"name":"Patchy-McPatchface","patches":["BADBED~DE~FE~CA~7E","BE~=~DE~FE~A7~ED","#~FADEDFAD~FAE-FEE-F00"]}
Patches are written to URL hash when the patches input lose focus.
Patches in URL can be shared easier than uploading a patch file somewhere.
Expand the section "Compare file (Diff hex bytes)" to generate patches for the differences between 2 files.
- This tool does not support extending or truncating files
- Huge files may not be patchable (since files are loaded and patched in RAM)
- Responsiveness is reduced when there's too many text in text input (only happen with Chrome, not FireFox)
Other tools that also support patches in URL:
- My fork of RomPatcher.js (patch files in URL) https://destitute-streetdwelling-guttersnipe.github.io/RomPatcher.js/#{"PATCHER":[{"name":"Boaty-McBoatface","file":"data:;base64,VVBTMQAgboMAIG6D+pUXwPqVF8AybecD"}]}
