The specs on that handheld are underwhelming. "By gamers for gamers" my ass-- you're certainly not going to get Saturn on that thing, so no portable SoTN w/ Maria..
PCEngine should be workable should a decent frontend for Mednafen appear, so at least there's Dracula X and the three Gradius titles on PCE.
Sorry, I'm in a bit of a Konami kick again.. I just picked up Gradius Collection a second time (imported on UMD way back before there was any hope of a US release) for my Vita.
