RChickenMan, Donkey Kong 1/2/3 run fine on my A620BT. Without sound they run really well, with sound I think it's a bit slow (I mostly played DK3).
Yoshi's Island's menu runs a bit slow, just like the game (can't remember if I tested it with or without sound though). I didn't test the other 2 games

.
One question for you, I am currently looking for another PPC (one for my little brother so we can multiplayer and stuff like that

). I don't need a very powerfull one, just a simple and nice looking one capable of running games like Warfare Inc., snails, etc. and it also has to support BT and/or WiFi. Now my question is; Does the 1910/1915 support BT/WiFi? Because I've heard something about the device not being able to use it or something.
Thanks in advance!
