GCYL: CEu
Currently in alpha. LV-UV should be playable. Breaking changes may come without support for your world. Find breaks in progression, overlapping recipes, missing recipes, useless recipes, etc. and submit problems and suggestions with GitHub issues.
Accelerated playtesting is reasonable now.
Gregicality Legacy Port to CEu (specifically with reference to the Technological Journey fork)
Requires this version of Gregtech: CEu, this version of Material Replication, and the latest versions of Gregicality Multiblocks, GroovyScript, ModularUI and their dependencies to run.
