I tried improving http://tasvideos.org/3935M.html but no progress had been made for over an year due to lack of motivation. For that reason, I'm releasing this so people can look at. It's 62 frames faster than published run iirc.
Tnis run syncs on Bizhawk 2.4.2 with console verification settings. (Console mode: GBA and CGB in GBA is enabled)
