This bites about the PS2 Ketsui port not coming out. They got this far with it and gave up? I think they could've given it a little more time. Warping slowdown I'm sure means frame-skip that looks like objects are "warping" from place to place, but there is a brief period of that in stage 5 on the PCB.
What a waste to have given up on it. Though I have the PCB, I'd also have bought this for any extra modes. If memory was a problem, I would not have minded a mid-level load in stage 5.
If the PS2 can't handle it as Arika would like, maybe they should make it for the Wii, which should have the power to do it 100%.
