Edit Reason: Rewrote some words and added more features list
)
Okay, I viewed the JavaScript code of the Online Patcher in the main site, then I searched for a new ROM patcher and found this repository:
https://github.com/marcrobledo/RomPatcher.js/
According to the readme, it supports applying IPS, BPS, Xdelta and other formats.
Edit: in the features list, it can show the CRC32, MD5 and SHA-1 before applying the patch, and it can remove headers before patching (like the iNES and SNES copier), so I suggest these features too.
