Version: Sega Master System PAL50hz
Console played: Analogue Mega SG (yes, Speed Demos Archive is now accepting runs done on Good Clone consoles, mainly Analogue's for now)
Why 50hz, there are a couple of PAL only Master System games that had runs done in 60hz, so why not this one?
The Game Gear version has the music speed identical to the Master System running at 50hz.
Secondly a lot of the best Master System games were developed by various teams from Japan where they are used to 60hz timing.
Games like Streets of Rage 1/2, Batman Returns, Sonic 2 and Sonic Chaos for the Master System have Game Gear counterparts and the music from the Game Gear is identical to the Master System running at 60hz.
Gremlin Interactive (aka Infogrames Studios) were based in the UK where the default hz setting before the Dreamcast was 50, not 60.
How does this glitch work?
At the moment I do not know the exact reason why it works but if the ninja is on a certain spot of the edge and press UP, the game simply freaks out and activates the Nth Dimension warp to the credits.
How easy is this glitch?
The turnaround method 1st try is the hardest but if you want to at least beat the game fast, you can try jumping from the lower left yellow donut to the glitchy edge, push UP and hope for the best.
The website is timing this under 1 second and Speedrun.com is timing it over 8 seconds how come?
Speed Demos Archive (this website) start and end the timer differently to popular community timing.
Speed Demos Archive starts the timer on first frame of control and ends on the first frame of losing control.
In this case it starts when I move left and ends on the first glitched frame.
Speedrun.com's timing starts when you press 2 on the menu "Gremlin Graphics" and ends when the screen fully fades to black after executing the glitch.
You could think of this like how people may prefer measuring stuff in Metric over Imperial but the timing conversion is different in every game.
Is this the fastest time for Speedrun.com (https://www.speedrun.com/zool_sega_master_system/full_game)?
No, this run doesn't do the 2 frame perfect pauses right after pressing UP to save 0.04 seconds.
Doing these extra 2 pauses to fade to black sooner would make ZERO difference for Speed Demos Archive's timing because it ends the moment the glitched frame appears.
TASVideos timing would end right after pressing UP because TAS runs are timed with the shortest possible input sequence, pressing the extra 2 pauses would waste 3-4 frames.
Ah the joys of different timing methods.
