Is this an edition? or a series?

edition: http://redump.org/disc/8530/
series: http://redump.org/disc/415/

Edition. AFAIK (I'm not a PSX collector, so can be wrong), all the titles in Major Wave series were also released as regular ones. Raiden DX definetely (original is SLPS-00728 and there's also SCPS-45019).
