SNK Playmore has officially announced a new PSP compilation of classic games for Japan, to be released on April 21. Unlike most SNK collections (like Metal Slug Collection and SNK Arcade Classics Vol. 1) that offer games exclusive to Neo Geo, SNK Arcade Classics 0 is a collection of 20 games made by the company before the release of the Neo Geo hardware.

Yes, finally, you'll be able to get Ikari Warriors and Athena on the same disc, along with Psycho Soldier, P.O.W., and a lot of vintage SNK games we've never heard of. Find the full list after the break, as transcribed by Andriasang. Many of them were originally released in vertical format, a setup emulated on PSP by holding the device sideways.

An ESRB rating for SNK Arcade Classics 0 has been online since late 2009, suggesting that SNK has plans to release this collection stateside. Of course, the rating occurring that long ago also means SNK has had plenty of time to change its mind.
