Submission #4248: coldsun0630's DS Sokoban DS in 2:39:07.44

Game objectives

• Emulator used: DeSmuME 0.9.9
• Aims for fastest time (to clear the game)

Addresses

• X Camera: 02156480 - Fixed Point, 2 bytes
• Y Camera: 02156488 - Fixed Point, 2 bytes
• Z Camera: 02156484 - Fixed Point, 2 bytes
• Steps: 020D9604 - Unsigned, 1 byte

Notes

• An each step requires at least 10 frames, but it consumes more when there are more objects in specific stages. For example, Stage 232 requires 12~15 frames for an each step.
• The way to spend the least frames for an each step is inserting one input into the earliest frame which does accept the input as a step. Touching the screen will spend 2 more frames than it, and continuing pressing the buttons may cause of delay between steps.
• While trying various ways to optimize between steps, I've found an exception to the method above. Let's see the 25th step at Stage 232. In this run, the step's input (using the method above) is on frame 458778, but if you add (206,166) to frame 458584, the 25th step's input at the stage could be on frame 458767. So, we can figure out that it saves 11 frames. (But this trick consumes more later frames so couldn't be used in this movie.)
• The re-record count doesn't show the actual count, because I re-recorded with text-editing most of the movie. This process would be very shorted if there were Piano Roll in DeSmuME.
• This run does not aims for shortest input. Since the game doesn't show credits automatically after clearing the whole stages, I added some inputs that show and end up credits for encoding. So, if you want to beat this movie, make sure to be faster than this movie which does aim for shortest input.

Possible Improvements

• Optimizing solution is the most simple way to save frames. This can save at least 10 frames per steps.
• Optimizing frame count between steps could be another way to improve the run. Try to optimize it with various ways like using touch screen, etc.
