just about to play Metal Slug 2 with my cousing online (multyplayer) with Kaillera.
Xmame dropped kaillera long ago,so now I'm running http://www.kaillera.com/files/mame32-067-414-ka09.exe
and its kaillera client works without a problem here on linux. I only had to set it up on windowed mode...
Oh and btw, It even picks up my joypad
and with sound,and almost no lag
by God, Wine devs are good.
Wine also works on another windows emulator with kaillera's netplay capabilities:
JneS. So if you wanna play some old school NeS game with a friend somewhere on the other side of the world, get jnes and open it with wine (again,it picked up my usb joypad!!)
