| Unlock everything | verified | OPTIONS gains EXTRA MENU. Gallery goes from 4/154 to 154/154. Kliff and Justice appear on the select grid, and Start opens the EX panel. The stage table has 34 selectable entries instead of 14. |
| Unlock Kliff Undersn | verified | Kliff's portrait appears at the left end of the grid. Tested with the identical byte write during bisection. |
| Unlock Justice | verified | Justice's portrait appears at the right end of the grid. Tested with the identical byte write during bisection. |
| Unlock GG mode | verified | Start shows MODE: AC / GG. Picking GG tags Sol "GG". |
| Unlock GGX mode | verified | Start shows MODE: AC / GGX. Picking GGX tags Sol "GGX". |
| Unlock all EX characters | verified | Start shows CHARACTER: NORMAL / EX. Gallery count +1 (the game's "all EX" award). Tested with the identical writes (bisection; gallery screenshot not kept). |
| Unlock EX (one character) | verified for all 23 | Only that character's code on: Start opens the CHARACTER panel, Down selects EX, Start closes it, and the pick sets P1's EX flag. The command list on the versus screen changes too. Control: with only another character's EX code on, the panel does not open for this character and the flag stays 0. |
| Unlock all gold and black characters | verified (gallery +1), see the per-character row | Gallery count +1 (the game's "all gold/black" award). Tested with the identical writes (bisection; screenshot not kept). |
| Unlock gold/black (one character) | verified for all 25 | Each character was tested with only its own code on. SLASH COLOR + R1 picks colour index 14 and variant 1 (gold). RELOAD COLOR + R1 picks 19 and variant 2 (black). Without the code, the same input picks colour 1 and variant 0. RAM was read after every pick and a fight-start screenshot taken. Writing only the high byte (0x0100) unlocks both for Sol and Justice: the u16 is one combined flag, and any nonzero value counts. |
| Unlock Extra Menu | verified | OPTIONS lists EXTRA MENU, which opens the per-player attack/defense/speed/tension/life/burst/guard settings. Tested with the identical byte write. |
| All missions cleared | verified | Gallery 4 → 34/154 (one entry per mission). Clearing missions also grants Kliff, Justice, GG/GGX and the Extra Menu, but only when you clear one in play, so use those codes for them. |
| All story endings | verified | Gallery 4 → 103/154. Also enables the "Unknown" stages (entries 14 and 54) and the story-linked Slash stages. |
| Gallery 100% | verified | Gallery 154/154. |
| Max play time | verified | After the play-time check runs (opening the Gallery or entering a mode), Kliff, Justice and the EX panel appear, and the GG/GGX bits read 3 in RAM. The stage table has 32 selectable entries: the Slash stages, but not the two "Unknown" stages, which come from story endings. |
| Stage select: all 34 unlockable stages | verified | 34 stages in the carousel on a fresh save. |
| Stage select: hidden stages too | verified | Together with the code above: 55 stages in the carousel, with their own names and thumbnails (the #Reload set 20-38, Russia, Nirvana, Slash Grave and Heaven). A first version that also enabled Korea (19) showed 56. Korea hangs when loaded, so it was dropped. |
| Stage select: (one stage) | inferred | Same write as the verified group codes, one entry at a time. |
| Load any stage | verified (entries 2, 20, 21) | The carousel cursor sits on the chosen entry. Cross loads it: Russia (2, never offered by the game), London #Reload (20) and Colony #Reload (21). Entry 19 (Korea) hangs, so it is excluded. |
| Holding R2 on a Slash stage loads its #Reload version (game feature, no code) | verified | Paris (Slash, entry 47) confirmed with Cross loads Slash Paris. Confirmed while holding R2, it loads #Reload Paris (entry 27). |
| Persistence (save while a code is on, then reboot with no codes) | verified | With Unlock everything on: OPTIONS > MEMORY CARD > SAVE, which formats our test card and overwrites the system data. Then a cold boot from the disc with no codes and no savestate. The loaded save has EXTRA MENU, 154/154 gallery, Kliff + Justice and the EX panel. Before saving, the same cold boot showed none of these. |
