Long term a new shader JIT based on control flow analysis should also fix this in a more proper way. Short term, the solution is as identified, but I also want to try a change where the shader buffer is cleared when a new upload begins, to see if that confirms my theory. Since the current JIT does no control flow analysis or compiles based on the entry point, these garbage instructions are still compiled and affect the valid code. While Generation VI had the Player Search System to make things easier, Pokémon Sun & Moon have a. Battles and Trades with other players has been the overall crux of Pokémon and a large part of why it took off. Communication has always been the most important aspect of Pokémon.

Near as I can tell, this game does not fill unused portions of the shader memory with 0, and this code is actually a left over from a previously loaded shader. Pokémon Sun & Moon - Communication Features. Installed Pokémon Sun / Moon updates will cause conflicts with the Nova Sun or Umbra Moon mod when installed as a CIA or 3DS file. In fact, there is a fair amount of unused code at the end of the shader. Looking at the code, there is one call instruction with a return matching the crashing position, but that call instruction can't be reached in any possible execution of the code. I wanted to investigate why this situation was even happening in the first place: why is execution reaching a potential return point without a call? It's possible the shader code was devious and re-using bits of regular code as a subroutine but I found that unlikely. The solution is to push a dummy value (such as 0xFFFFFFFF) on the stack at the start of the execution of the JIT. In this case, a value left on the stack by the caller of the JIT happens to match the IP, causing the code to execute a return from subroutine even though there had been no corresponding call in the shader. This check peeks the value on the stack and compares it to the current IP, and if it matches, does a return. Current situation: already found what's causing the crash and how to work around it:Įxecution reaches a potential subroutine return point, where the JIT inserts a check for a return.
