1.7Gb ..... maybe not.
There was a problem with the button mapper that caused lag and problems when multiple buttons were pressed at once. Modern Combat 4 *was* unplayable, which was pretty annoying as I paid a fiver for it. on the 27th Archos released a new firmware fixing the button mapper and now MC4 runs perfectly.
I'm really happy with it, played it more in the last week, than the 5 years I owned a PSP!
