I'm necrobumping this thread because this game deserves a new TAS. There are many new tricks found and the route has changed. The RTA record is currently
58:45 by exe, but sub 58 is definitely possible. In a TAS, the new stuff could potentially save 4-5 minutes.
Here are the major differences of the RTA route compared to the one the TAS uses:
- 1 additional remote in Mao Tse Tongue
- 1 remote less in Honey I Shrunk the Gecko
- 1 additional remote in Pain in the Asteroids
- Skips Rezopolis
For information about the new tricks, check this thread at SDA:

Regarding the emulation, this game seems to work fine in Bizhawk. The bugs I found are only graphical (and are the same ones you had in Mupen). The best plugin is Glide64 (Glide64mk2 doesn't work at all).
