there was some progress in Sega Triforce emulation in few last days in Dolphin, so now MKGP2 is can be called "playable" after last commit to Triforce branch.
It is still very preliminary - uses a lot of patches/hacks, testmode not working, etc, but anyway good to know another arcade system was reverse engeneered and emulated.
