RAM/Memory address mappings

Hey,

Before I spend more time on it, has anyone done any memory address mappings in Bizhawk they could share? I’m interested in finding the actual speed of the standard/special/shinobin boards for each rider to double check the in game displayed stats are accurate.

Cheers

I have not. I have only dabbled with the SBK2 item numbers so maybe some kind of manip or patterns could be found ;o; I'd love to see streams of this happening though if you're going to do that...!?

These are the interesting ones I've found so far (all numbers I have listed are unsigned 1-byte):

121D85 - Character ID 0=Slash 1=Nancy 2=Jam 3=Linda 4=Tommy 5=Sinobin

1121E5 - I think it's something like percent of max speed. Has values 0-127.

12201D - Board speed? Whole number (don't know where the fraction value is) So initially I thought this was the final speed value but the values don't change based on the character so it's specific to the board selected. I used the start of Sunset Rock (before the first drop and rock) and measured each board 4 ways.

I think I should redo this test on Night Highway as you can build a little more speed in a straight line from the start.

I still haven't cracked the value that controls speed (ie. if you freeze 12201D it has no impact on their speed) which is disappointing but I went through and mapped a bunch of other things which can be found here: https://docs.google.com/spreadsheets/d/1U1rHQYOiwVavRJRuvrvssmzrvMY_LVt5CiGU_tOCFqM/edit?usp=sharing

With those values you can do some funky things like getting Sinobin riding a Star Board, or tricking the game into playing Trick Mode on a track other than the Animal one only. Without the real speed value though, it's hard to find things that would be useful for speed running.
