Q: Can you add more seed category? A: Yes, if you find a good seed and at least 2 people made a run of it, this can be added on the board.

Q: Why is banning a character not allowed? A: To make the competition fair, everyone should keep the same settings as much as possible. If you ban Big and Gamma for example, you will get different stages and will complete them faster than if you had Big or Gamma in that case. In other word, you will get an unfair advantage. Also, I don't want this speedgame to be just people who ban everyone except Sonic and Tails, as they are the most broken characters in this game.

Q: Why is quitting a stage not allowed? A: Again, to make the competition fair, if people start quitting everytime they get something which take too long, this would be unfair against people who don't, specially for custom seed.

What is “IGT / in-game time”?

IGT means in-game time, it’s generally used when the RTA is not fair enough. In fact, we call that IGT but as for SADX, it's more like "balanced RTA" because the game runs to a totally unstable framerate (depending on the hardware / OS and other factors.) For example, the game is running faster on Windows 7, so we have set up a Balanced RTA (or IGT whatever) represents the what your time would be if there were 60 frames in a second. So as for SADX, “IGT” is like a frame counter.

How do I set up the IGT?

Why is my IGT higher/lower than my RTA?

This is quite normal, again, the game doesn’t run at a stable 60 fps, so if your game is running faster than 60 fps (which is common) the timer will accelerate. However, it will slow down if your game is slower than 60 fps (or if your loads are just bad.)
