I am not sure I understand, do you mean that instead of adding `-p15:32:32`, I add some default values for all other reserved pointers as well and leave it at that ?

Or do you mean add a generic way to upgrade pointers here, for example by creating a small map and automating this entire thing instead of having multiple if/else ?
