I was messing around with using the tank to get on the guard tower, and a bad jump made me notice that there are invisible ledges on the corner poles of the guard towers. This involves two "jump backwards into double-jump forwards" tricks. I haven't actually gotten a full run with it live yet, but it should be somewhere between 8-10 seconds faster than the tank skips.

--Update (March 14, 2016)--

We have decided to only allow emulators for single level submissions. You must use official game consoles for full game runs.

--Original Post--

I have added a section to the SDA wiki about emulators, and I will copy it here. If there are any concerns or updates, please post them below. Note that these rules can be changed at any time if runners abuse them.

The use of emulators will be allowed on 2 conditions:

1. The emulator has been proven to have an accurate in-game time
2. Single level runs must include video evidence of the run, with a time on the "scoreboard" screen at the end of the level that reflects your video time.

¤Note: Because of how resets work in this game, in order to fulfill condition #2 you will need to fully exit the level and enter again in order to reset the in-game timer.

As of 5.0 RC-1, Dolphin Emulator has been proven to be accurate enough to submit runs from.

In order to determine if an emulator is accurate enough for submission, record a level that displays an in-game timer during the level itself, along with the end of level time. If both of these timers match the length of your video, then that emulator can be considered accurate. Wasteland Thunder and Race to the Rocket are both good levels to test this with.

Runners should note that most emulators for this game require a rather powerful computer to both play and record without slowdown. If the in-game time does not match the time spent in the video, the run will be rejected.
