Since people are ALSO having some trouble getting the ROM of Mega Man X3, I added it in the Emulation page. So you can play it too with the great Zsnes 1.0!
Hey, this is the great day: C4 CHIP EMULATION IS DONE! PLAY MEGA MAN X2 AND X3 NOW! You can get the working version of Mega Man X2 from the Emulation page. I'll add all emulation related stuff here as soon as I can (over the next week or two).
