@blakespot So now I try both versions of everything I want to play, that I used to run from WHDLoad always.
Well in the case of the CD32 version of Wing Commander it's a patch as much as a hard drive installer. The CD32 Akiko chip was used as a Planar to Chunky accelerator but the game had a small but significant error in the software code (a bit like Aliens: Colonial Marines A.I. code) and hence ran like a dog. The error was found and the game was patched to run well with accelerator instead of the Akiko. Hence, the WHDLoad version is the definitive version of this game!
