The record

Purpose: Pokémon ROM Patcher applies a patch to a Pokémon ROM and returns the patched game as a download.
Local processing: The patch is applied by JavaScript on the user's device, and the page says files are never uploaded or received by Pokepatched.
No installation: The patcher runs in a browser without installing anything.
Supported ROM file examples: The base ROM drop slot lists .gba, .nds and .gbc files.
Mobile support: The patcher says it works in any modern mobile browser, including for files used with Delta on iPhone or a GBA emulator on Android.
Wrong base ROM: The page warns that using the wrong base ROM can cause a crash or checksum error and says hacks may require a specific release, such as US version 1.0.
Existing hacks: Applying a second patch is supported only when that patch was built for the already patched file; the page recommends starting from a clean ROM for each hack.
Dependencies: The patcher is powered by RomPatcher.js, which the page identifies as MIT licensed.
ROM sourcing: Pokepatched says it does not host or link to base ROMs, and users supply a game they legally own.
Maker: The About page describes Pokepatched as an independent, fan-run index of Pokémon ROM hacks.
Support: The contact page lists submissions, corrections and takedown requests as reasons to get in touch.
Affiliation: Pokepatched says it is not affiliated with, endorsed by or sponsored by Nintendo, Game Freak, Creatures Inc. or The Pokémon Company International.
ROM file types: The input slot accepts .gba, .nds and .gbc files.
Automatic format recognition: The patcher recognises the patch format automatically after the user loads the ROM and patch.
