- ROM-hack players applying community patch files
- Worth noticing
- BPS and UPS reject checksum-mismatched bases; IPS does not, so a successful apply may still use the wrong dump.
Field notes
The instructions tell users to match the patch author's region, revision, and hash guidance, and to keep the original base ROM for trying another patch. Hash matching is limited to the listed FireRed, Emerald, and Mario 64 references; the page says other hashes stay blank. It also distinguishes checksum behavior by format rather than presenting every successful apply as proof that the input was correct.
