 "explanation": "$v0 took 6 DIFFERENT values inside one frame ([5, 8, 85, 136, 155, 939873691]). The fade is one level per frame, so every vertex should see the same value. A per-vertex scale multiplies the same source colours by different amounts -- which is exactly the extra colour variety psx-runtime shows and DuckStation does not."
