GBA Core splitscreen multiplayer (Patreon)

I hope you have some friends to play with, because I made a special version of the GBA core...with 2 GBA cores in one MiSTer FPGA!

You can download a testversion directly here as attachment.

How does it work?

Most features needed to be stripped out of the core to make it fit twice into the FPGA.

There is no VGA out (only HDMI), no Savestates, no Fastforward, no Turbo mode, no Shader colors, no 2X HD rendering, no filters.

Instead, you get 2 raw GBA cores, one connected to SDRAM, one connected to DDR3, communicating directly inside the FPGA. Sound is used from Core 1 only.

Implemented for multiplayer are the 2 most common link modes (GBA has 4 different modes). Most multiplayer games should be supported.

You can watch the video linked here or try it yourself.

I hope you have some fun playing together!
