PPSA14632 (Unreal Engine) writes sceAgcCbBranch(mode 1, compare function 0, mask 0, reference 0) with a then buffer and a null else buffer of 0 dwords. It leaves the compare address uninitialised, so it is sometimes only 4-byte aligned. The writer rejected the null else buffer and the misaligned compare address, and the driver accepted opcode 0x3f only as the 4-dword INDIRECT_BUFFER, so the 14-dword branch would have failed at submission. sceAgcCbBranch no longer checks the compare address of an always-pass branch, which reads nothing, or the address of a buffer of 0 dwords. The driver runs the first buffer of an always-pass COND_INDIRECT_BUFFER in modes 1 and 2 (if-then and if-then-else) in place of the packet. A comparison, a predicated branch and other modes throw.
