Tested male Red, Zhar, and Xor.
Xor has a broken ini, it tries to install PMHT06_XorD.mdl and PMHT06_XorD.mdx but the actual files are called PMHT06_Xor.mdl and PMHT06_Xor.mdx.
Red has one fewer DS transition than normal, stages 2 and 3 are identical. If that's intentional you might as well reference the same image files twice in the 2das rather than have two identical files with different names.
Probably not a bug, but Zhar sticks out as having wildly-different skintones for his face vs his limbs.
