MiSTer2MEGA65 Color Schema

MiSTer2MEGA65 Color Schema

This page is dedicated for showing the color schema used in the MiSTer2MEGA65 project, done by sy2002#5425 and MJoergen#8874.
You can connect with me as MegaBeauvais#9623 on the MEGA65 Discord server.

With the below, you can click the RED + GREEN + BLUE + DARK + INVERSE boxes and get the color code values.
These hexadecimal values can be used directly in the MiSTer2MEGA65 code - most likely in the M2M/rom/sysdef.asm file.
You should always use the combined value - the other values are just for information and intermediate results.

The colors in the MiSTer2MEGA65 can only use 0% or 100% RGB values - so "0" or "255" - no 33% or alike allowed.
DARK halves the brightest color - so "255" would be "127".
INVERSE shifts background and foreground colors.
An example:

Yellow background would be 100% red + 100% green + 0% blue = 0x20 + 0x10 = 0x30
Purple text would be 100% red + 0% green + 100% blue = 0x04 + 0x01 = 0x05
Combined background + foreground would then be 0x30 [logical OR] 0x05 = 0x35
If DARK was added then that would be 0x40 [logical OR] 0x35 = 0x75
If INVERSE was added then that would be 0x80 [logical OR] 0x75 = 0xF5

Do note that the colors shown here are not a real representation of what you will see on the MEGA65, but it gives at least a good idea of how it will look.

Click on the below boxes:

Background	0x20	0x10	0x08		0x00
Foreground / text	0x04	0x02	0x01		0x07
Dark	0x40				0x00
Inverse	0x80				0x00

Result of combined background + foreground				This is a test text	0x07

It seems the magic number you need to use is 0x07 :-)
