Does the psp 290 work better with the psp slim??? Because i used to have a psp 290 with my psp phat and it sucked!!! So i got a holux 240 and it works a lot better, but i know that the holux cant as of now work with the psp slim. So i read that the psp 290 now works better with the slim because there is not as much interference within the system, is this true???
