Synopsis
Hypothesized Official Name: SignExtendHL
Syscall Address: 021D80h
This was originally a buggy call, and still is in OS 5.0.0.0089 (and others, perchance?) But after sending in information, TI did an amazing job and fixed this call. It basically performs a sign extension on a 16bit HL to 24bit HL.
