Welcome to the end.
For those that want to know how White Chamber goes normally
watch the DS TAS this chamber is busted in the original version.
There is one major thing to note. A Key and a Pink Button share the same slot, at any point you grab the pink button, the key becomes invalidated, causing you to be softlocked. Placing the pink button into the remote doesn't help either. The key is invalidated at any point you touch that pink button, so the sequence showcased, is the sequence that avoids getting stuck.
Two files are required for this one, cause that's how it was bundled, a start.swf and a "main21.swf" in order:
CRC32: 11E8513C

When playing the movie back, load the start.swf file.
slamo: Claiming for judging.
slamo: Oh hey, there's the last one! Optimization looks great again, it's neat that you can skip some parts in the original version. Accepting!
