What's exclusive in this compilation is that Xevious Arrangement and 3D/G have the arrange soundtrack in addition to the original. However, the FMV videos are likely to be different than the arcade version of Xevious 3D/G although I don't know what's with the ending, like shooting at the giant ancient symbol on the sandy ground to summon the beam that wipes out the enemy fortress in space. Maybe this ending is what STH4E2 ending should have been in the first place like getting out of the Death Egg II and returning back to the planetary surface and if you have all the emeralds collected, you can use them to wipe that out.
Unfortunately, the PS1 version of Xevious 3D/G has even more flaws than ever. It has lack of graphical and environmental details as well as the blocky looking polygons compared to the arcade version. Also, the effects are mostly polygonal like there's no signs of sprites being used in the game. Also, when I played Xevious 3D/G on my Playstation Vita, there was a huge amount of lag in Area 3 when going through those rotating ring shaped wooden stuffs where there are still ground enemies to take out.
I may be glad to see this having come out in the PSN Store for Playstation Vita. Also, thankfully, there's auto-firing for easier playing. Video captures of the gameplay with arrangement soundtrack will be on my YouTube account soon after this blog post.
