Yeah I would. I'll probably sell my current Everdrive at some point and get the Mega. I just like all the new features plus the huge-ass rom size (80mb) which is great for homebrew and special audio and video recordings and other such nonsense.
The Turbo Everdrive cannot have a savestate. He'd have to make a Mega Turbo Everdrive.
Now somebody figure out a way to play HES files on real hardware please!
