The first 2 bytes seem to store general information like whether we're in a level or on the overworld, while the second 2 bytes describe the status of the player. The 'status' of the game is stored in memory variable 0800 in 4 bytes. When viewed as a HEX variable, displays the life count in decimal. If this value is nonzero when hitting a level transition, it causes a 'banana block.' This holds bananas as they move towards the counter. When viewed as a HEX variable, displays the banana count in decimal. This value is inverted, 0 denotes full stamina and 10 is empty. The sixth bit (64) counts the extended roll 'credit.' Other bits seem to hold other information (for example, 5 = 'inside barrel cannon'). For some reason, Expresso and Winky also get their speeds set to 0 when they land from a jump.Ģ-byte HEX value denoting current state of the player, see 'Status Table.'ĭisplay as 2-byte to show subpixel only value.ĭisplay as 2-byte to show pixel only value. Animal buddy speed and acceleration values are the same as the Kongs' when not mentioned. I included a lot of values for anyone who is curious, but some are not super relevant so I highlighted the important ones in bold. In the following table I will give measurements in these units as well as in pixels as a rounded decimal, and pure subpixels, to make them easier to think about for anyone who prefers those units.

In this document I primarily give measurements as pixel_subpixel, these units will be denoted with an underscore to separate the place values. In hindsight I probably should have switched to using subpixel only measurement, but I got set in my ways. Furthermore, with the subpixel value unsigned, to read leftwards and upwards speeds you have to add the negative pixel value to the positive subpixel value, making them harder to think about.

This has the advantage of making the significant figure easier to see and reference, but the disadvantage of making computations and comparisons harder. When I started working on this TAS I made the decision to keep my subpixel and pixel addresses separate and measure as a sort of a 256-decimal. For position in the level which requires more than 256 pixels, another byte is used to store superpixels. Lengths are stored in two separate bytes measuring pixels and subpixels.
