Secret of Mana Randomizer (formerly Secret of Mana Ancient Cave) is a multi-mode randomizer for the SNES game Secret of Mana. Applied to a copy of the US Secret of Mana ROM, it randomizes the location/layout of various game elements.

Currently included/under work:

- Vanilla game randomizer: swap locations of enemies, bosses, elements, and other things in the base game.

[Completion: ~85%]

- Open world: Grant access to Flammie immediately with various options for progression/difficulty/completion of the game.

[Completion: ~75%]

- Ancient cave: procedurally generate random dungeons, with random bosses and Mana Beast at the end.

[Completion: ~50%]

- Boss rush: encounter all bosses in a random order, while managing HP/MP resources to survive the whole gauntlet.

[Completion: ~65%]

- Chaos: Like Ancient Cave, but with vanilla dungeon maps randomly connected together.

[Completion: ~70%]

To be added sooner or later:

- Bingo: Open world mode but with in-game randomized bingo board as the primary objective.

[Completion: ~20%]

Other features/fixes:

- CPU player warp: instead of getting stuck on the edges of the screen, players 2 and 3 will warp to you when scrolled off.

- Status indicators: flash player character palettes to indicate current status effects, similar to FF6/Chrono Trigger.

- Randomized weapons: with random status effects, elements, and names/descriptions pulled from a variety of sources.

- Magic rebalance: Adjust the costs and effects of some spells to account for being able to use them earlier in the game. Also, modify Speedup spell to grant movement/recharge haste effect.

- Imported music: various tracks from other games, most with Secret of Mana's sample set, some with their originals.

- Increased inventory size: Hold up to seven items instead of vanilla's limit of four.

- Autosaves: Automatically save the game to slot 4 on most door transitions.

- Various other things
