jEnesis is a Sega Mega Drive and 32X emulator programmed in Java by Stephan Dittrich. Its emulation is pretty good, although the YM2612 and DAC timings are a bit incorrect. The emulator takes around 5-10 seconds to start, but it runs pretty fast though.

Sega licensed the emulator for use on their in-browser gaming service PlaySEGA.[2]

jEnesisDS is a Nintendo DS port based on this emulator done by the same author, although most of the emulator has been rewritten and is now regarded as one of the best Mega Drive emulators for DS.
