EZ Register GUI
by zebek
EZ Register GUI is a Fabric utility for building and monitoring redstone registers from an in-game window, aimed at players who construct redstone computers.
What it does
Players set up a register with a single command and then watch its contents through a configurable GUI window. The window can be dragged with the left mouse button, and each serial monitor shows a green or red symbol beside its name that reports whether monitoring is running or paused. Registers can be grouped, and a right click selects the current group. Display modes include base binary and hexadecimal, and the mod can color code values.
The tool recognizes redstone components that carry powered, power or lit tags, and it can read signal strength through a memory-based setup. Bit length, block spacing and marker rendering in the world are all adjustable, and a configuration template saves profiles that can be loaded again. Registers default to eight inverted bits spaced two blocks apart vertically. The mod requires Fabric API and Fabric Language Kotlin, and it is released under All rights reserved, so it is not open source. Files exist for 1.20.4, 1.21.4, 1.21.5 and 1.21.8, with 0.5.1 for 1.21.8 as the latest build.
