This uses Android code.

Command(s) from here are constantly used while displaying gfx.

TransactParcel is used by 1.0.0 official user-processes, while starting with {unknown version} TransactParcelAuto is used instead.

== TransactParcel ==
Takes a s32, an u32, a type-0x5 input buffer, a type-0x6 output buffer, and an input u32. Each word is immediately after the previous word.

== AdjustRefcount ==
Takes 3 input s32s, with each word immediately following the previous word. No additional output.

== GetNativeHandle ==
Takes an input s32 and u32, with the latter immediately following the previous word. Returns an output event handle.

== TransactParcelAuto ==
Takes a s32, an u32, a type-0x21 input buffer, a type-0x22 output buffer, and an input u32. Each word is immediately after the previous word.
