SEGA Genesis & CD Games With Tons of Slowdown

[wingzrow]

What SEGA GENESIS/SEGA CD game had the most slowdown during gameplay?

My overclocked JVC X'EYE is almost done. When it arrives, I would like to show a friend the difference between a SEGA genesis game with slowdown, and the same game with the overclock setting on.

I know Sonic the Hedgehog 2 is a prime example with it's 2 player mode essentially running the same game twice, but what are some other games I would notice a large performance difference in?

I own a lot of Genesis games, but it's hard to remember any of them slowing down. That says a lot about the Genesis. I do seem to remember Midnight Resistance slowing down in parts, and I remember moments of slowdown in Sonic when you hit something and lose a lot of rings. Good luck with your project.

Lightening Force will almost at times slow the mighty 68000 processor to a halt. Try that one.

I have thunderforce 3, does that slowdown at times?

Although, i do like lightning force so maybe it's time to add it to my collection.

Pretty sure you can achieve some pretty severe slowdown in Dune 2 or Herzog Zwei if you just build enough units.

Over clocking won't change anything that is access time dependent, so many CD games won't work.
Lunar 2 had some issues, mostly due to disc access but the the battle against Zophar takes forever to load the battle menus in the 4th round. The semi cut scene at the end of that battle is also pretty sluggish but a bit less so than the beginning. I couldn't find a video of the English release but I remember it being a bit worse. Here is a video of the Japanese version http://www.youtube.com/watch?v=Gy67N5OJjDY fast forward and watch at about 3:18.
