Native GBA menus still displayed imported or hardcoded labels after an API-3 mod overrode the corresponding rom_text entries. Bind the FireRed/Emerald party action readers and their separate cancel buttons, plus FireRed's Item-PC withdrawal title, cancel row and submenu. The same public consumer runs through both engines without renderer replacements.

FireRed uses the reference's sCursorOptions[n] keys; Emerald uses its named labels through the real manifest branch. Keep primary TAKE/action CANCEL/footer labels distinct, preserve native fallbacks and action identities, and read the Item-PC title live so retiring a mod restores an already-open menu. Custom/TOSS titles retain their own text.

Depends on #171. Incremental change: parent #171 → this branch.

Validation:

• 257 shared reader checks and 62 native action/render/retirement checks.
• Eight isolated SDK workers / 522 paired native text values, against clean Gen1Recomp 535a5ec; reference API 3 vs host API 3 and API 2/unified. Deterministic public label/table provenance; no cartridge text included.
• Full feature run: 137/147 engine suites, with exactly the same 26 failure lines across ten baseline suites as Add shared ROM-prose registry and native Gen-2/GBA storage readers #171. SDK 3/3 and B30 pass. Combined runtime 7a12243293dcb7a6ff2a00dc64490f3c6bb5aa32, including test: repair Gen2 updater asset fixtures #128–134 repairs: 192/192, SDK 3/3 and B30 pass.
• Native LÖVE 11.5, isolated imported FireRed/Emerald: real party draw, SUMMARY open/B-return, ITEM submenu/B-close and party close. FireRed additionally enters withdrawal through Player PC, draws the title/list/submenu and selects translated CANCEL without inventory changes.
• Imported Red: battle 468, save conversion 95, parity J 73 and K 22. The unchanged Add shared ROM-prose registry and native Gen-2/GBA storage readers #171 negative control still displays BASE_SUMMARY after the same public override.
• New Lua formatting, actionlint, Python compilation and diff checks pass.

Further party prompts/mail/trade/field-move names, Item-PC quantity/results, Emerald's distinct Item-PC screen and battle prose remain separate work. Native smoke does not claim normal SAVE, full playthrough, fresh full-ROM import or pixel equality. Hosted CI is separate from local validation.

Hosted CI at publication: all 32 PR workflows report action_required pending maintainer approval. The GBA menu-prose workflow has zero executed jobs; these are not hosted-green results.
