An SD Card (you can use any, even a 2GB one)
This may seem like such a silly question to some of you (especially if you're an avid time trialer), but do you TT against your current ghost? Obviously I understand how this can help at times by watching your own ghosts to see your mistakes and then be able to tell if you're fixing them in real...
Watch in 720p.
Finally, new track texture is coming right now! So, I made this texture of SNES Ghost Valley 2 named is Red Darkness Valley. :)
