Cheats

Space Invaders Cheats

Mame's cheat system is very powerful and very easy to use. However, it's quite complicated to get running. The cheat system is a LUA plugin which needs to be enabled to run. It also requires that the cheat option to be enabled, on the configuration menu, or in the mame.ini file or as command line switch. I won't be showing how to make your own cheats as it is very complex however, there is a guide here. Anyway, here's how to do get the cheat system enabled...


.

The Cheat File

The cheats in Mame are XML files. There are thousands of them so the cheat system supports a 7Zip archive of all the files called cheat.7z. You can download the official cheat file by Pugsy from here. Once downloaded, all you need to do is drag it over to your Mame folder. As for the LUA scripts, these are already in place as they are included in the Mame distribution.

Enable The Plugin

There are two ways to enable the cheat plugin. You can open the plugin.ini file in a text editor such as Notepad and change the 0 next to cheat to a 1. You can also enable it in the Mame user interface menus. There is a "Plugins" option on the panel under the games list.

Plugins Option

Click it and you'll see this menu...

Plugins Menu

To enable the cheat system, turn "Cheat plugin" and "Cheat finder help library" to On.

Finally, you need to enable the cheat menu in Mame. As I said above, there are three ways to do this. The first way is to do it from the "Configure Options" menu.

Plugins Option

From the settings menu, select "Miscellaneous Options".

Settings Panel

You will now see this screen.

Set the cheats option to On and the cheat system is now running. This option will save when you exit Mame.

You can also enable cheats from the command line. Add -cheat to the command line options to enable the cheat system. Here's an example

mame64 -cheat
mame64 <system> -cheat

Finally you can edit the mame.ini file in a text editor and change the 0 next to cheat to 1. The cheat options is about halfway down the list under # CORE MISC OPTIONS.
