Used RAM - pk-hack/CoilSnake GitHub Wiki

More advanced scripts may need to make use of their own RAM locations. Luckily, there is some free space available that isn't used by the game. You can find the layout of RAM here and in CCS format here.

If you are making a script that utilises RAM space, here are locations that are already in use by other scripts. If you make a distributable script, add your locations here for future programmers, and make sure to update "Next free space".
