Gex 3: Deep Pocket Gecko is a pretty standard platformer for the Gameboy Color. In it you must collect 23 remotes from the various levels in order to reach and defeat the last boss.
This run is a major re-routing of the original, following the RTA record and suggested by andypanther. This is responsible for most of the time save.
A new trick used in this run is pausing out of a stage after collecting a remote, eliminating many end level cutscenes.
Aside from these two things, other small optimizations are made along the way. Most importantly the flies that give you power ups are used correctly. You can simply press select to eat a fly and activate its power, something mmbossman did not do in the original. Doing this saves several seconds worth of backtracking and waiting in the anime stage and a little in the hero stage.
This run is console verified, as in the temp encode.
