I honestly think the Game Boy port of Alien Wars/Super Probotector is outright crap. It looks and sounds a lot worse than Contra GB/Operation C. It's slow, is full of sprite flicker, has some badly drawn sprites, and very poor background shading. The overhead stages survive a lot better.
I don't think it's much on an achievement when Contra GB/Operation C is just so much better in every possible way. Alien Wars GB is just a mediocre piece of GB software. And as a personal pet peeve is uses that horrible C64 style euro-warble effect in the music, bleugh!
Metal Gear series (especially 2) also has music in that style. Really Konami's entire output during the 80s was just raw riffing on 80s movie (and golden age Hollywood for Castlevania) pop culture. It's cool to a point but I'm glad they eventually settled on more distinct identities for their properties. I love the goofy tongue-in-cheek cyberpunk that Hard Corps settled on.
Metal Gear is a good example, Metal Gear Solid had a cinematic soundtrack, but I think more 90s than big 80s Goldsmith. Spirits is fully Rambo+Total Recall.
I mean, apart from the obvious Rambo influence, Contra Spirits is pretty much a straight riff on this:
Metal Gear 2 was stuck on the MSX so couldn't have the orchestral grandeur of Contra Spirits in the same way the Famicom Contra games didn't either (though Super Contra had an orchestral hit sample as part of its soundtrack to achieve some of it). Contra Spirits was the one that finally fulfilled the original aural vision IMO.
