I see not much is posted in relation to discussing the PiSTORM.
I didn't know until the other day, someone created a tweaked version of WHDLoad.
Its basically a wrapper, that alters Emu68 command line options on the fly. It checks its database for game your attempting to run, then alters PiSTORM config to allow that game to runs without glitches.
Have to say, this is final piece of puzzle for my new setup, I have been working on.
So, if anyone uses WHDLoad with PiSTORM, check out WHDLoad Wrapper.
