We’re confident this is the PsOne version since Sony Computer Entertainment America is listed as the publisher, not SNK Playmore who have their own list of still unreleased NeoGeo games for PS3 and PSP.
Metal Slug X is also part of Metal Slug Anthology, a fantastic collection for fans of SNK’s run ‘n gun series, but that version is missing combat school missions where you can chat up the instructor just like Metal Slug 7 or XX.
