Mobile note: patching requires holding a 64 MiB ROM, a ~54 MiB patch and the generated ROM in browser memory. Modern mobile browsers may work, but low-memory Safari sessions can fail. Desktop Chrome, Edge or Firefox is the safest fallback.

Runtime proof

Not a screenshot-only release.

The public gameplay recording demonstrates the rough-English RC1 running in actual gameplay, including early English dialogue and the opening progression that previously exposed the branch bug.

The branch bug

English changed the bytecode map.

Variable-length English text shifted EVC bytecode, but an earlier rebuild left absolute branch destinations pointing at the old offsets. The opening YES route jumped into the wrong place and froze. RC1 rebuilds those destinations.

Known issues

RC1 means public QA.

Some residual Japanese UI or notification text can still appear, including mail-related UI.

The lower-screen English font can be difficult to read.

The translation is intentionally rough and has not received a full literary edit.

Graphics/font cleanup, battle QA and full-game QA are not exhaustive.

Traditional patching

Want the BPS only?

Use the same canonical RC1 patch in Floating IPS or another standards-compliant BPS patcher.

Prior work

Built in a real translation lineage.

Vector Translations' public beta is acknowledged as prior work and technical reference material. That beta covered the first three chapters. This RC1 is presented as an independent rough-English completion/rebuild effort, not as a claim that no earlier English work existed.
