They use the 20 star door skip (they have 20 stars when doing this, but i'm pretty sure that's still not allowed)

But more importantly they somehow get a replica in key 2

Good find!

insanity, thanks for having a keen eye man

Yep, SMSR still uses the old any% ISC rules which bans all sequence breaks, including 20 star door skip. The run has been removed from the leaderboards.

The replica being there in B2 is the fault of a specific version of the game but that version is also not allowed for runs. Good catch, idk how this run stayed up for 4 years
