Randomizer Changes

2026-07-13

Quad Randomizer - Version 0.5.1

Systems Changes

  - An advanced playthrough view for logic events, flags, strategies, and complete routes is also available
Gameplay Changes
- Added an Early Morph Ball option for Super Metroid and Metroid 1, which places Morph Ball in an early reachable location when enabled

- Fixed Super Metroid Mother Brain and Tourian access logic issues

Quad Randomizer - Version 0.5.0

Systems Changes
- Any combination of games can now be chosen for a Combo seed - ALTTP is no longer forced to be included. Cross-game portals are generated dynamically for whichever games you pick, forming a full mesh of connections between them (direct SM↔M1, SM↔Z1 and M1↔Z1 portals in addition to the ALTTP ones); portals belonging to absent games are automatically reassigned to the games that remain
- Added a “Include spoiler log” toggle on the config page (for race seeds) - turning it off hides the spoiler from the seed’s public page while still generating the seed
- Added a Metroid 1 generated map viewer to the spoiler log, showing the rooms, area layout, doors/elevators and item placements of a shuffled M1 world
- A large batch of NES rendering fixes for Zelda 1 and Metroid 1 during and after cross-game transitions (Andypro)
  - Fixed a “ghost Link” appearing for the first frames after entering ALTTP through a portal
  - Fixed sprite, tileset and tile-attribute flicker/corruption on door and portal transitions in both NES games
  - Fixed bomb clouds being drawn behind dungeon priority tiles in Zelda 1, and the priority tiles staying black during the bomb screen-flash effect
  - Portal destinations can now select the correct area palette (fixing wrong colors when arriving in Brinstar/Norfair)
Gameplay Changes
- Added Super Metroid, Metroid 1 and Zelda 1 as directly portal-connected games in Combo - all four games are now woven together rather than everything routing through ALTTP
- Added Metroid 1 Map Shuffle - generates a completely new randomized Metroid world map instead of the vanilla one (NOTE: this is in early testing, so expect potential bugs and balance issues)
  - Map Size option (Small, Standard, Large, Nightmare) controls how large and dense the generated world is; Nightmare saturates the grid, growing every area until nothing more fits
- Added a Zelda 1 “Book reveals maps” option - the Magical Book reveals every dungeon map instead of its normal function, which is handy when playing with shuffled dungeons
- Added a Zelda 1 Dungeon Shuffle “Map placement” option (Off, Early, Closest) - forces each generated dungeon’s Map into an item room near the entrance instead of shuffling it anywhere in the dungeon. Early keeps it within roughly the first 30% of the dungeon (scaled to dungeon size, may be behind a locked door); Closest puts it in the nearest item room. Either way it avoids being hidden behind a bombable wall when possible
- Added Zelda 1 Shop Shuffle option (Off, Junk, Full)
  - Junk: shop caves sell randomized consumables at randomized prices and never gate progression
  - Full: shop slots join the main item pool and can hold progression items, gated in logic behind cave reachability and possession of a farmable weapon
- Fixed a batch of NES item graphics issues when items from one game appear in another (Andypro)
  - Fixed Zelda 1, Metroid 1 and Zelda 3 custom NES item sprites and palettes showing the wrong colors or graphics
  - Fixed the Metroid 1 Fire Rod sprite colliding with the vanilla Ice Beam item, and duplicate progressive-item sprites loading when several copies spawned in the same area/dungeon
  - Fixed the Wrecked Ship keycard receipt graphics in Zelda 3
  - Fixed Zelda 1 heart container sprite graphics
- Fixed a Metroid 1 bug where a “mellow” enemy in a certain enemy slot became indestructible and erratic (Andypro)
- Improved Metroid 1 item persistence with a new bit-plane collection system, replacing the overflow-prone item/door history that could cause shuffled items and doors to respawn
- Softened the Zelda 1 ocean wave sound effect so it is less grating (Andypro)
Hotfixes
- Fixed an issue with Z1 items/state when Z1 is the starting game (0.5.0a)
- When SM is the starting game with map randomization on, the starting room is the Crateria portal (0.5.0a)
- Fixed another Z1 dungeon state bug when Z1 was the starting game (0.5.0b)
- Fixed a bug that let progression items end up as take-anys in Z1 (0.5.0b)
- Fixed a bug that put a Z1 to M1 transition inside vanilla Level 9 in Z1 (0.5.0c)
- Improved M1 Map Shuffle logic to better consider specific screen combinations (0.5.0c)

2026-06-01

Quad Randomizer - Version 0.4.0

Systems Changes
- Added a “Settings” help page describing every setting available in the Basic options view
- Added a dungeon map viewer to the spoiler log for Zelda 1 generated dungeons
- Made the Combo hint fallback more obvious when no specific hint is available
- Overhauled the NES audio engine used by Zelda 1 and Metroid 1 to emulate the NES APU at a much lower level (Andypro)
  - More accurate length counters, DMC sample length and register write handling, fixing short sounds, mid-playback sample switching and incorrectly silenced channels
  - Added a noise complement channel for better white noise, reduced audio latency and optimized CPU/SPC communication
Gameplay Changes
- Added Zelda 1 Dungeon Shuffle - generates brand-new randomized dungeon layouts instead of the vanilla ones (NOTE: this is in early testing, so expect potential bugs and balance issues)
  - Dungeon Style option (Progressive, Wild, Megadungeon, Nightmare, Minimal) controls overall size and complexity
  - Enemy Placement option (Vanilla, Progressive, Random) controls how enemies are chosen for generated dungeons
  - Hidden Items option (Off, Sometimes, Always) controls whether dungeon items are hidden until the room is cleared
- Improved ALTTP entrance shuffle by overriding certain outlet locations so players can no longer get stuck
- Fixed an ALTTP logic issue where the logic wrongly assumed that you could walk back from cactus to throne room
- Added a few more enemy bans in ALTTP that could cause issues (Ganon’s Tower, Ice Palace, Swamp Palace)
Hotfix: 0.4.0a
- Fixed Zelda 1 dungeon progress (collected items, explored rooms on the map, defeated bosses and the triforce) resetting in level 1 and the bottom row of level 9 after returning from another game - the dungeon state region was being overwritten during the transition by the restored routine data and the temporary stack
- Fixed a Zelda 1 generated dungeon softlock where the shutter behind the triforce room (levels 1-8) closed on entry with no way to reopen it, trapping the player after defeating the boss
- Fixed Zelda 1 generated level 9 dungeons where the triforce gate could be bypassed - a cellar stairway connected to the entry check room, or shutters being reopened by an adjacent room, could let players into the rest of the dungeon without the required triforces
- Fixed Zelda 1 generated dungeons placing item locations inside walled-off “chute” rooms (the screens with a sealed middle passage) where the item could be impossible to reach; rooms whose layout would strand an item are now rejected, and as a safety net any item still left unreachable swaps the room to a layout that can be picked up
- Fixed Zelda 1 generated dungeon logic not requiring the Stepladder to clear a room whose kill-required enemies can only be reached across a water gap, which could leave a kill-gated door or item unobtainable
- Fixed a Zelda 1 bug where enabling both Overworld shuffle and Dungeon Shuffle would cause “Take any road” stairs to freeze the game
- Fixed Zelda 1 generated Minimal dungeon size to generate properly
- Improved Zelda 1 dungeon generation reliability by reserving grid space for cellar and stairway rooms, preventing occasional generation failures
- The spoiler log for quad combo seeds now properly shows the game which an item is from
