Do you own a modified Genesis?
This week I bought a "High Definition Graphics" Model 1 Genesis with S-Video and stereo jack modifications. It also has a overclock switch that gives the option to set to factory 7.6 Mhz or an overclock speed of 10 Mhz. There is a Japanese/English region switch and another 50/60 Hz switch that allows for fluid PAL gameplay. The cartridge slot has been seemlessly widened to accomodate Japanese carts. Overall I feel I'm set to enjoy my collection in a whole new light. :D
