📄 Description

Improves the build target CPU architecture by setting to btver2 (Bobcat Version 2 - the name used by compilers for AMD Jaguar), which matches the actual PS4 CPU. SSE4a is explicitly excluded to not inadvertently use AMD-only instructions.

This enables more instruction set extensions than approximating with sandybridge does, increasing support for potential optimizations while still preventing the CPU requirements from exceeding those of games themselves.
