Learn how to convert batch graphics for use in Rm2k/2k3, Game Maker (Old Version), MMFusion (Old Version) and other engines that use 8-Bit graphics.

An example is the images in this topic, originally the size of 378 Kb (24/32 bits), now the size of 120 Kb (8 bits).


Downloading FastStone PhotoResizer (http://www.faststone.org/FSResizerDownload.htm).
Alert: If you are not the administrator of your machine download the portable version.

Browse or drag all images into the software.

Turn on the "Output Folder" option and set a folder to store the converted graphics.
Do not do this in the same folder, you may damage the original graphics.

If you are running Windows Vista (or higher) and need to use MSPaint to do any editing, the image will be converted 24 or 32-bit again..

The required settings have already been applied:

Click on "Details", the Bit Intensity line should be number 8.
If it's 24 or 32, that's why you made a mistake converting.
