Sonic 1 2013 Tails FAQ      

Q: What does 2013 mean?
A: It refers to the year this remake was released, to distinguish from the original version.

Q: What is different about this version?
A: A fair bit. The engine is slightly different, so mechanically there are slight difference everywhere. For the less keen observer; all the zips are such from the original no longer work, Tails can now carry you as he flies, speedcap can be turned off, and elemental shields from S3K can be added into the game.
 
Q: What are you playing on, it is emulator?
A: Yeah, I'm playing on Bluestacks, so emulating Andriod.

Q: Why do you use ingame time and not real time?
A: Because http://www.youtube.com/watch?v=RaMGf1V3MMM | Time Bonus causes going slower to be faster for RTA, which is hyper dumb
 
Q: What is the timer you are using?
A: It is the In-Game timer function of Livesplit. I enter all the times manually at the end of each level, and it produces the splits.
 
Q: What is the World Record?
A: https://www.speedrun.com/Sonic_1_2013#Tails_Beat_the_game 

Q: Do you have a goal time?
A: Just to get the record I guess
 
Q: Are there glitches in this run?
A: The only useful glitch is the "water glitch", where if you jump out of the water while only very slightly submerged, you jump really really high. This is ideally seen at the end of Scrap Brain 3, but isn't required at all.
