sceKernelSignalSema threw invalid_argument for a count of 0. Marvel's Wolverine (PPSA03671) signals with a count computed as min(a, b) - c, which can be 0, and ignores the result, so the throw ended the title a few minutes in. A zero count now adds no tokens and returns SCE_OK, as in shadPS4 and Kyty. A null semaphore and a negative count still throw. guest_kernel_errors signals 0 on a full and on an empty semaphore and checks that the count is unchanged.
