Most accurate emulators for each system? MESS included

[Juanie]

I'm trying to get perfect emulation of all my roms, and this is probably the right place to ask.

Thanks

You can never get truly 'perfect' with an emulator, but try going to the Emulator Zone homepage, select what system you want, then choose the emulator at the top of the page, they are always the best.

Try using Fusion (http://www.emulator-zone.com/doc.php/genesis/fusion.html) which emulates many systems, and Chankast (http://www.emulator-zone.com/doc.php/dreamcast/chankast.html) which emulates the Dreamcast.
