I did find the basic values such as x camera position, x position relative to the camera and something related to animation cycles in the RAM. Did not do any hard digging for boss hp values or such.
Mainly for this I just used prince_leaf's fastest TAS on youtube as a reference point but without an actual input file I have no idea if I was faster or slower than what he did.
Haven't really found anything substantial, there is a slight glitch where the water death animation can slide along the moving platform and then over the crocodile and into the wall but you still die anyway.
This is just a quick test, everything seems relatively sync friendly at least up til the first boss. Only one jump height, annoyingly.
