Thanks to everyone that has been posting their impressions of the R4. When my ds lite comes I think i'll order one. I was just wondering if beup (homebrew msn messenger for ds) will be compatible with the R4. If someone could test it i'd really appreciate it. Here's a youtube video of beup in action (looks pretty cool): http://youtube.com/watch?v=MDjMCSEHLxE Here's a link to the download: http://www.mediafire.com/?4myim0mgkzm I really hope it works on the R4 because I definitely want to use it. Thanks to anyone who takes the time to try it for me.
