There is another bugged opcode that I think would be nice to fix. Opcode 0341 (SET_TEXT_JUSTIFY) cannot full justify text at all because after CFont::SetJustifyOn is called, either CFont::SetRightJustifyOff or CFont::SetRightJustifyOn are called and both those functions turn off full justification. The fix for GTA III is to nop 0x501D77 7 bytes, and for Vice City nop 0x550047 7 bytes. This prevents full justification from being switched off in CFont::SetRightJustifyOff.
I apparently ran tests on it in 2016 and did not like the result.
