« on: April 15, 2019, 11:06:19 pm »



Introduction:
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).



Tutorial:

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.

Alert:
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:

If it's 24 or 32, that's why you made a mistake converting.
