RCT3 UI Scale v1.2
UI scaling mod for RollerCoaster Tycoon 3: Complete Edition (Steam) — makes the
UI usable at 1440p / 4K by scaling the GUI2 reference canvas (fixes both visuals
and mouse hit-testing).
New in 1.2
[Signatures]INI overrides — users on non-Steam / non-Complete editions
can paste their own lever addresses (raw RVAs and/or AOB signatures) instead of
relying on the built-in Steam signatures.[Diagnostics] DiscoverSignatures— read-only porting aid: the mod scans
the running game, validates the UI canvas against your live display resolution,
and writes a ready-to-paste[Signatures]block to the log. (Requires
LoggingEnabled=1for now.)
The stock RCT3 Complete (Steam) experience is unchanged — all new keys default to
off/unset.
Install
