“No pity for bad players”
These wonderful crazy French bastards modded a Sega Genesis to deliver a shock every time they took damage, or died in a host of different Sega Genesis games including: Sonic, Golden Axe 3, Mega Man, and several others.
This would be a ton of fun to play with a friend, not so much solo. I could just imagine running full speed with Sonic, then suddenly without warning: CRASH, ZAP, CHING! If you thought retro games were punishingly difficult already, you might want to avoid building a “GeneZap” of your own.
