Robert is on fire with his MiSTer core improvements

This time it is another handheld split screen multiplayer core, having now squeezed two Gameboy Color cores into one MiSTer FPGA!

The separator line color is the same as the background colo for gbr: white on white or black on black.
It is black for gbc.

[FPGAzumSpass]

Oh, i never use monochrome GB mode, so i didn't notice it.

What about making it red for GB mode?

[jca]

What I meant is that it is not visible in gb mode and I think it should be black when Inverted color is No and white when Inverted color is Yes.
Having only 1 controller I cannot really enjoy the core and I think it would be better if people who make real use of it give their opinion. I also do not know what it involves on your part: may be using a single color is easier but I think changing the color depending of the setting of Inverter color should not too difficult for you considering the admirable job you did with the GBA2P and Gameboy2P cores.

[FPGAzumSpass]

I just thought something with more contrast would be better, but color depending on inverted option is about the same effort.

[jca]

As I said it does not matter too much to me as I cannot really make use of it, other users are better suited to give their opinion.

Hope you'll be able to load 2 different games that are capable. Also feature to load a gamesave for each of the games would be cool for the times when your playing the same version game and want to use 2 different saves..
For Pokemon for example.blue vs red/yellow. other games come to mind.

But good core.Good idea.

when you are trading or battling, you dont need any version exclusive parts from it, afaik. you can still load pokemon red saves in pokemon blue, or pokemon gold saves in pokemon silver and pvp or trade that way. not sure how yellow or crystal affects this, but at least blue/red, blue/green[jap] and silver/gold save are compatible with each other
