So I finally bought the Thinkoutside Bluetooth keyboard, and this thing is awesome! It's absolutelly excellent for text input and the keyboard shortcuts are very handy. But I've found one drawback. This keyboard hasn't proved itself very good at gaming. I've tried it with a variety of game demos such as Acky's Breakout, Atomic Cannon, PocketNES, and Skyforce without much success. There is a long pause between the time I hit a button and the time I see any action on screen and some, namely PocketNES hardly work at all. What I find odd about Skyforce, though, is that I'm pretty sure that it was advertised to work very well with the Chainpus Bluetooth controller. How can I minimize this lag? Why would the Chainpus controller work while the keyboard won't? Is it just a problem with bluetooth, or is it a software issue? Could I possibly do something like use a driver from the Chainpus website? Thanks!
