GB Super Mario Land 2 in 2:09 (TAS) by MUGG and andymac

Info:
Many months ago, I managed to find a byte (0xA2D5) in the out-of-bounds area that would trigger the credits upon altering it and entering the next level. Very soon after, andymac created the 2:28 run ( http://tasvideos.org/1721M.html ). Now I found a way to complete the first level faster, thus this 2:09 run came along.

Back then, andymac listed me as an author for finding the 0xA2D5 credits trigger even though I didn't create the actual run. This time I list him as an author due to him making glitched SML2 TASing what is is now - without him, it wouldn't be possible, or at least, it would still be at 2:45's time...

Please note that 0xA2D5 isn't actually a credits trigger - it never is written to during the course of the game, and always remains "0". Apparently altering it screws the game physics up so badly, it would try to load the next best thing within the game, which happens to be the staff roll.

Also, the "new" pixel trick is used in this run, which consists of jumping a lot and changing directions at certain frames which gains you a few pixels, thus saving time.

For questions, ask away.

Erm... ive never seen anyone going THAT far in the glitched area, it just always freezes before you could get anywhere deep...

Nice run!

Because the upper half of the glitched area is ROM data in the game, followed by switchable ROM, then VRAM, then SRAM. ROM data may not be written to, so whenever a write occurs (by breaking blocks or collecting coins) the game locks up or resets. A2D5, the byte that needs to be broken, is in SRAM.
