Optional assists

Health freezes current HP at 255 with PAR codes 7E0520FF and 7E052100. Magic freezes current MP at 255 with 7E0522FF and 7E052300. These affect runtime memory only. Both begin off; no equipment, story flags or quest items are granted. They do not prevent falls or bypass boss magic restrictions. Address evidence: TASVideos Lagoon research (Nasir sprite base 0500, HP +20, MP +22) and Ugetab’s HP / MP code entries.

Checklist and saves

The manual checklist has stable IDs, browser persistence, Completed, undo and file export/import. It does not detect in-game events. A snapshot contains game state, checklist and assist choices, bound to the cartridge SHA and Snes9x legacy core 2.0.2. Personal ZSNES/Snes9x saves are kept outside the website; compatibility is not assumed.

Runtime and corresponding sources

Retained EmulatorJS 4.2.3 collection build and Snes9x legacy core 2.0.2, copied from the collection’s published Shuushoku 1.0.1 reference. The core binary embeds no commit: exact rebuilding from the retained source reference is unverified.

Guide references

Concise newly written objectives based on factual game progression; full guides remain with their authors: tankMage / RetroMaggedon, Cless Alvein / RPGClassics. Browser startup, English text, assists, checklist and snapshot checks are recorded in the development note. Full campaign replay and physical controller verification are separate, unclaimed checks.
