I've been practicing No Starworld but when I try to do FOI2 Yoshi clip I either miss it completely or get stuck Inside a block where I can only go up and no other direction. How can I avoid this?

I have been starting to run 11 orb and even when everything is going correctly when Yoshi eats the Clappin' Chuck my game usually crashes. Any tips to avoid this? Thanks.

Is BizHawk allowed? Given that it is just M64+ on a different program.
