Original Mobile Route
You are here when: The FOMA 903i application menu, keypad configuration, and first controllable room.
The original network service is retired; preserve an untouched archival copy before recording progress.
Use the Original FOMA 903i Release
Setup
HintThis game was built for one Japanese feature-phone family.
WhereRun the original 2007 i-mode application on compatible FOMA 903i hardware.
Full detailUse an authenticated original handset installation where available, keep its application and downloaded data together, confirm the title reaches both modes, and clone the storage before creating completion data.
Document the Archival Launcher Limitation
Setup
HintThe modern preservation route does not contain every historical unlock.
WhereIf using the preserved launcher copy, record its build and confirm that extra characters are absent.
Full detailKeep the preserved package unmodified, note the launcher version and package hash, and open the character-select screens in both modes. The recovered copy is reported complete for ordinary play but lacks extra-character data, so it cannot prove an original-release 100% roster.
Verify Both Key Types
Setup
HintThe application permits a control-layout change.
WhereOpen settings and test each available key type in a safe room.
Full detailFor each key layout, confirm the direction pad moves, 2 toggles running, Confirm examines or fires, the right soft key raises or lowers the weapon, and the left soft key opens the menu. Retain the layout that produces no stuck inputs.
Calibrate Aiming and Target Selection
Setup
HintCombat changes the meaning of the direction pad.
WhereRaise a weapon and test vertical aim plus left-right target changes.
Full detailEnter a repeatable early encounter, hold the aim soft key, use Up and Down to alter elevation, then use Left and Right to cycle visible targets. Fire once with Confirm and verify releasing aim restores ordinary movement.
Episode Mode
You are here when: The outdoor Uptown blocks and enclosed police-station corridors joined by branching objectives.
Public documentation gives an approximate episode count, not a complete branch table.
Start Episode Mode from Clean Data
Mode
HintBranch tracking is clearest without inherited flags.
WhereBegin Episode Mode on a blank save and record the first objective message.
Full detailCreate a clean profile, select Episode Mode, copy each displayed objective into a private ledger, and save at every offered transition. Do not use plot wording in public notes; identify branches by geography and objective type.
Clear Every Uptown Episode (missable)
Route
HintOne half of the route uses open streets.
WhereComplete every Episode Mode branch whose playable space is Uptown.

Clear Every Police-Station Episode (missable)
Route
HintThe other half uses enclosed corridors.
WhereComplete every Episode Mode branch inside the police station.

Clear Every Cross-Area Branch (missable)
Branch
HintSome objectives move between the two physical regions.
WhereReplay branch points until every route connecting Uptown and the station is recorded.

Register Every Objective Message (missable)
Objective
HintShort messages disclose what opens the next node.
WhereRead every unique objective message across all Episode Mode branches.

Record Every Episode Route Result (missable)
Result

WhereReach and record every distinct terminal result shown by Episode Mode.

Mission Mode Pyramid
You are here when: The pyramid-shaped stage-select screen and the compact Uptown or station challenge maps.
Official launch coverage says roughly one hundred nodes; no surviving public table establishes the exact final count.
Reveal the Full Mission Pyramid
Mode
HintStage clears expose additional connected nodes.
WhereClear available missions until no unopened ordinary node remains on the pyramid.
Full detailBegin at each exposed base node, satisfy its displayed objective, remain through the results screen, and revisit the pyramid. Continue every newly opened connection; do not assume an approximate published count is an exact total.
Clear Every Mission Node (missable)
Mission
HintEach short stage has its own objective.
WhereFinish every selectable ordinary and hidden mission on the pyramid.
Full detailNEEDS_VERIFICATION
Earn S on Every Mission (missable)
Rank
HintTop results unlock additional paths.
WhereReplay every cleared mission until its results screen displays S rank.
Full detailNEEDS_VERIFICATION
Open Every S-Rank Route (missable)
Secret
HintSome pyramid connections appear only after exceptional results.
WhereAfter each S rank, return to stage select and inspect every new branch.
Full detailBecause public sources do not preserve the node-to-node unlock table, photograph the pyramid before and after each S result, clear every newly exposed node, and repeat until an S rank no longer changes any connection. Exact nodes require original-build verification.
Complete Every Objective Type (missable)
Mission
HintThe compact stages vary their success condition.
WhereRecord and finish every distinct objective wording used by Mission Mode.

Original-Release Archive and Unlocks
You are here when: Character selection, equipment menus, results records, and the completed mission pyramid.
The preserved 2025 package is explicitly reported to omit extra characters.
Unlock Every Extra Character

WhereOn an original complete installation, unlock every additional playable character.
