There are definitely more powerful budget CPUs and hardware starting to appear that hopefully we will see in the next generation of handhelds. These provide the next level of performance needed to run N64, Dreamcast, PSP, PS1 etc really well.

Take a look at this video of a Chinese budget 10.1" tablet review, called the M40. It's only £126 but can handle emulation of PSP at full speed, including God of War. It seems to handle N64 fine too. The big surprise for this price is near prefect Gamecube emulation and even able to handle some PS2 and Wii. Imagine in another year we might see something from Anbernic able to run nearly everything up to the PS2 and Wii. That would be very nice indeed. Would never be able to decide what to play!
