--[[ 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).
1 player X, Y
1 camera X
enemy data
enemy data size 19
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
