Gameboy Core splitscreen multiplayer (Patreon)

Another handheld splitscreen dualcore: two 2 Gameboy (Color) cores in one MiSTer FPGA!
Testversion is added here as attachment.
It works about the same as the GBA splitscreen core, but some things are changed:
- Core Name: "Gameboy2P", so you may want to either add games in this folder or create a symlink
- Splitscreen is horizontal only this time, as the aspect ratio works by far best this way
- No dual monitor support. Sorry, but GB doesn't have a DDR3 framebuffer mode and I will not add it
- some features are stripped out: Cheats, Savestates, Fastforward, Super Gameboy
- double buffer mode is removed, instead the core got a "Sync video" like the GBA core has. Use it if you notice tearing
- CRT output untested
- both cores are running from shared SDRAM
There is also a video again, so you can see what it looks like.
Thanks go out to to rattboi, who made a proof of concept about 2 years ago of this core.
