RE4 Randomizer - January 2026 patch

Hello again 👋 hope everybody is doing well there.

There is a new patch available which has many new options and improvements:

• Now the randomizer can load and save custom setting profiles using the new controls added for it, and from now on, these profile files will be compatible with all future randomizer updates.

• Portuguese and Japanese were added as languages for the interface (at 'Misc. options' tab). There is also an option to cycle through different colors.

• There is a new tab "Enemy Settings B" with sliders to set the ratios for all non-ganado enemy types. You can also set how many of these enemies can spawn per room too.

• For the door rando, a new room is available (Siege tower). This was originally an unused, unfinished beta room, which now has functional door triggers and some enemies too.

Other changes for the door randomizer are:
• Simplified logs/easier to read. Now all logs are located in "Seedlogs" folder.
• All triggers/panels/cranks in both rooms of Ashley section (r20d/r20e) work correctly when playing as Leon, and the orange entry door that's usually locked now is a working door.
• Other areas enabled are the Laser room and the Wrecking ball room. For the second, a trigger was added to be able to climb up to the elevated area for backtracking.
• The false bottom room, which is seen only as a cutscene in regular game, is also a working room with a single exit.

• The elevator leading to Saddler that was a dead end in previous patch now will lead to a random area.
• There is an option to enable or disable Saddler boss encounter (for Assignment Leon mode only).
• The underground passage that usually leads to the graveyard now will always lead to Saddler boss fight (if it's enabled).

• Two doors that would be disabled after events (Verdugo boss area entry door and Prison entry door with Ashley present) now will work at all times.
• The crushers at novistador cave will also work as intended at all times, even if the exit elevator has been used.
• The side of the door that connects the Bingo room with Mendez house path is temporarily disabled. The boat at the lake and the cabinet trigger to check on Luis will also stay disabled.
• Some specific rooms (as Salazar boss area) will only be available if Assignment Leon is disabled to prevent softlocks.

• A new sound effect was added for the main menu when playing Assignment Leon mode. There is an option to disable this in 'Doors' tab.

Other changes:
• There is an option to set directly the total amount of yellow herbs that should be given per run ('Items' tab). I recommend to adjust this based on the Leon starting HP setting you set. Besides these, there is also another option to set Ashley's starting HP too.
• Fixes for bugged buttons of the interface not loading correctly (at Inventory tab) and crashes when backtracking to the first room of the game with Ashley following.
• There is an option to move the enemies away from the exit door at Bingo room (for day and night versions).

*****
Down below you should find the zip file to download, and a document with the instructions to install the mod.
It's recommended to delete the old RE4_PC_Randomizer folder before extracting the new one, because many folder names and files were changed.

For people having issues with x3daudio file I recommend to whitelist the whole Resident Evil 4 folder in your antivirus settings then extract all the files again.

If there is something else not working as intended please let me know in the comments below. Good luck!
