MESS W32 Commands
This section deals with configuring and running MESS for Win32. t includes where to start, an in depth look at the command line and a section looking at the MESS.ini file.
Where to start...
The beauty of MESS for Win32 is the fact although it looks like a DOS file it is actually a windows based program. Therefore you don't have to mess around configuring drivers as it uses DirectX and your windows drivers.
All you need to do to run it is to open a command prompt. Either go to the start button, press run and type command or you can run the command prompt from the start/programs/accessories menu.
Once you are in a DOS box type in this command
cd C:\MESS
You should see the prompt
C:\MESS>
If it is the first time you have run MESS type MESS -cc. This will create a file called MESS.ini which holds all the default MESS settings.
Command Line Options
MESS for Win32 uses a straightforward command format to execute. Heres what it looks like...
MESS <system> <device> <software_name> -options
System - Is the name of the system to be used which can be found here.
Device - Is the name of the device MESS need to emulate to load the software. This option is relevant to the system you want to use for example an Atari 2600 uses a cartridge therefore this option would say -cart
Heres a breakdown of the device names...
-cartridge / -cart | Cartridge based software |
-floppydisk / -flop | Floppy disk based software |
-quickload / -quik | Quick Saved Memory |
-printer / -prin | Output to printer |
-snapshot / -dump | Memory dump (e.g. exact copy of a systems memory that can be reloaded and run) |
-cassette / -cass | Cassette tape image |
-harddisk / -hard | Hard drive image |
-parallel / -parl | Data normally loaded through a parallel (printer) port. |
-punchcard / -pcrd | Punch card data |
-punchtape / -ptap | Punch tape data |
-serial / -serl | Data normally loaded through a serial port |
-cylinder / -cyln | Data loaded from a metal cylinder (really old computers used these) |
You can find out the devices used and what file extensions can be used by typing
MESS <System> -listdevices
From there it's up to you to decide what the software is. The way to look at it is that most consoles used cartridges, most computers used cassettes or floppy disks and newer computers used harddisks. You probably wont find many hard disk images about and most of the other devices (e.g. punchcard) are very obselete. Snapshot is probably the most commonly found file especially in home computer emulation as it is a complete system dump and when loaded will run software from exactly the point that it was saved from.
Software_Name - is the name of the file that you want to run in MESS. You must remember that you need the whole file name including the file extension (e.g. frogger.a26 or frogger.zip)
Options - Finally you have the options. Most of the options are exactly the same as Mame but there are a few exclusives.
These are all the command line options that MESS uses...

Heres an example of running MESS at the command line...
MESS a2600 -cart defender.a26 -now
This will run defender on an Atari 2600 using the full screen. As you can see it's not too hard once you've got over the amount of options available to you. If your brain is frazzled and you want an easier MESS use the GUI version as it's much easier to configure.
MESS.ini File
Rather than using the command line to set up the options you want to use in MESS you can adjust a file called MESS.ini. This is where MESS stores it's default configuration information.
To edit the file in windows find the MESS.ini file in the C:\MESS folder (it will have an icon next to it that looks like a text pad with a yellow stamp on it) and then double click it. This will automatically bring up the MESS.ini file in notepad. There are several parts to it and as you can see they relate to the command line options above.
The format of the file is simple to follow, most things with a yes / no answer are denoted by 0 for no and 1 for yes. there are also a few numerical options (e.g. gamma) and a few that require a text answer (e.g. rom path)
If you configure this file correctly you wont need to add options onto the command line.
Don't worry if you muck the whole file up because if you can delete it and, if you run MESS -cc again it will make another.
