Scuba gear is no longer necessary, as a new initialization data search method is now available for those who wish to use it:

In an actor's initialization data, the first two bytes, which normally represent the actor's number, should be replaced with the bytes 0xDEAD. Ten bytes later are two unused padding bytes, which we replace with 0xBEEF. See seagull.c for an example of this applied in C. You may also omit the Initialization section of conf.txt.

Additionally, two new tutorials are live, geared towards setting up mips64gcc and and compiling actor overlays written in C.
