It sure does support indirection mutliple times:
#include <acknex.h>
int i = 0;
void main()
{
int* p1 = &i;
int** p2 = &p1;
(*(*p2)) = 1337;
printf("%d",i);
}

That is wrong. SpeedRun_Time is a pointer. You write the address 60 to that pointer. What you intended to do was setting the integer value SpeedRun_Time was pointing to, right? Exactly, so I shud *SpeedRun_Time = 60; right?? And thats really not funny of the compiler (  ) to show crash in so and so but it isn't the crash there(Many might not be knowing :D) and it's the line preceding the function call.

Have you initialized your pointer?

The compiler has already done all of its work at that time, so you can't blame him. In general: There might be scenarios where writing an address to pointer is valid. The most basic usage of this is "MyPointer = NULL". That is basically the same. This is one of the unlucky cases where you encounter errors previously done much later - or never at all. EDIT: @JustSid: He did.

All C books show " *variable = value;" but that dint work. it should work:
#include <acknex.h>
void main()
{
int * int_ptr_to_mem = sys_malloc(sizeof(int));
*int_ptr_to_mem = 1234; // >> *variable = value; <<
int output = *int_ptr_to_mem; // printf doesn't work with pointers as value
printf("int_ptr_to_mem = %.0f", (double)output);
}
...works fine for me

You can of course diretly use printf.
#include <acknex.h>
void main()
{
int * int_ptr_to_mem = sys_malloc(sizeof(int));
*int_ptr_to_mem = 1234; // >> *variable = value; <<
printf("int_ptr_to_mem = %d",*int_ptr_to_mem);
printf("address of int_ptr_to_mem = %p",int_ptr_to_mem);
ptr_remove(int_ptr_to_mem);
}
