As a matter of fact, I have a video on my phone of me engaging in the final battle of Earthbound on the Pokefami DX - no freezing, no SRAM erasing. All good. I'll try to upload this quickly today so people who don't believe a clone can possibly get around this issue can ...erm...believe it.
I'll put up a better video over the weekend, once I've had time to shoot and edit an actual review.
Also - a few more observations:
-I tightened the screws on the device and the power switch works properly now - no more shutting it off simply by touching the switch.
-Apple headphones work fine...mine are just busted.
-I left the Pokefami DX running the title screen of Super Mario World (with the sound off, since we were sleeping) when I went to bed last night around 1am. When I woke up at 6:30, it was still running. I'd been testing it for about an hour before that...so you're looking at a battery life that is *at least 6.5 hours!*
-Almost every game has visual distortion when using the included speakers....like the RF interference kind of distortion I mentioned seeing in Yoshi's Island on the Supaboy. However, plug headphones in or plug the unit into a TV, and the problem goes away completely. Obviously this is an issue with space, as the louder you turn up the sound, the more distortion occurs.
-Again, headphones or no, the sound is fantastic out of this device.
-I put in my copy of Kirby Super Star last night - the one that never booted on the Supaboy - and it ran. I turned it off, then went on to test other carts. Then I tried to test Kirby again, and couldn't get it to boot again. I tried re-inserting it around 30 times...no dice. I hear this is a common occurrence amongst users of clones. The cart still works fine on my SNES.
I'll upload that Earthbound video shortly.
