Required Mode(s) For "4 Edges" (Demoscene)?

I've installed a few Demoscene CD-Images on my HDD for use with OPL and they all launch successfully apart from 4 Edges, which freezes at the first White debug screen when launched with OPL. It works fine under HDLoader 8c.

Which modes are most likely to help with running this? I imagine it's a problem with memory allocation as it's a homebrew app, but I've tried modes 1 and 3 to no avail.

It's not imperative that I can fix it, as I can always just run it with HDLoader, but I'd prefer to be able to launch all my Games and Homebrew without leaving OPL.
