Introduction

MicroLua Simulator (also abbreviated as MLS) is a very useful utility for MicroLua developers created by a member of our community, Ced-le-pingouin. It allows you to test your Lua scripts for NDS directly on your computer.
MicroLuaSimulator also has a debug console, and some useful features that may make you prefer it rather than DeSmuME.

Usage

Running a script

With File/Open, you can browse your files and open Lua scripts. You can also pass the script to test as an arg on the command line.

Controls

Buttons

Here is a comparative list between the controls of the NDS and those of your computer:

DS	Keyboard
Up	I or 8
Down	K or 5 or 2
Left	J or 4
Right	L or 6
A	D
B	X
X	E
Y	S
L	A or R
R	Z or T
START	Q or F
SELECT	W or V
Stylus	Mouse

Shortcuts

You can use some shortcuts in MLS:

Shortcuts	Effect
Ctrl+O	Open a script
P	Pause the script
B	Restart the script
C	Show/Display the console
DEL	Clear the console
F1	Reduce FPS
F2	increase FPS
F3	Reduce UPS
F4	increase UPS
F5	increase the log level
Ctrl+Q	Quit MLS

Ctrl key is Command key ("Apple") on Mac OS X.

Know limitations

Sound

Due to the lack of sound libraries, there is currently no sound in MLS.

Software emulation

What most differentiate MLS from DeSmuME is that it does not emulate the NDS executable but instead recode the functions provided by µLua to be used on the computer in a NDS-like interface. Thus it cannot be as reliable as DeSmuME or as a real test on hardware.
