I'm in the same boat. I think the PCE version has more fluid gameplay, but on the other hand the MD port has the Omake music tracks. It's a tough one.A copy of Devil Crash in fantastic condition I ordered from Japan a few weeks ago finally arrived today. Paid well below the usual eBay scumbag price so am well chuffed.
I still can't decide which version I prefer, the original on PCE or the MD port by TechnoSoft.
