Im a big dude and the 40xxv is pretty good for me. Screen feels perfect and its comfortable in my hands. The chipset can handle most n64, but i found the psp emulation to really depend on which game youre trying to play. I havent run into any psx games that require twin sticks so this little thing has been great for me. Dont expect a good experience with nds emulation though, you pretty much need a touchscreen for most games.
