--[[ MESHUGGAH's HUD Template 

NES Hokuto no Ken 2
NES Fist of the North Star
Bizhawk 2.6.2

This template features an example to NES Hokuto no Ken 2 (Japan) and NES Fist of the North Star (USA).

To use this in FCEUX:
	replace memory.read_u16_le with memory.readword
	
To use BIGGER text for the hud:
	replace gui.pixelText with gui.pixelText
