So, I've had my R4 for a while. I just used the default firmware and used the default games on the SD card. After a while, those games got boring and I learnt how to put on new games and delete old games. So that's been going on for a while too, then I learnt how to modify the CHEAT.DAT file. And I've been doing that a lot, and I've recently upgraded to Wood R4. So I've heard that you could do many things using an R4, not just play DS games. You can listen to music, look at images, watch films, use VoIP to call phones, access Facebook, Twitter, Myspace, check e-mails, surf the web and plenty of other things. I just have one simple question: How? I've looked up guides on Google and Youtube and haven't learnt anything about this. Could anyone explain how to do a few of those things listed above? I would be most grateful to any helpful answers. Thanks in advance..
