Broke down and grabbed it on the PS4 (well, PS5 in my case). So far so great. While its only 4 of the games (wish it was all of them, including the C64 and NES releases but hey) it still seems like a pretty decent series of ports so far. Tried Turrican 2 as I know that game rather well, and it plays like a dream. The addition of a proper jump button is probably the best QoL change I could have asked for. Extra lives are everywhere, more so than I remember - if you explore off the main path chances are a 1up or two are there.
Options wise, the screen options are pretty darn good. Aside from the usual screen ratios and screen filter, I was surprised at just how tweakable the CRT/scanline filter is, its really in depth.
Honestly, I only have two issues with the ports so far and neither are really a problem. First off is I can't view the trophies. I can unlock trophies (you get one for using the super smart bomb, another for beating the optional UFO boss on stage 2) but the list doesnt appear. Oh well, that'll be fixed soon Im sure.
The second issue is that the game loads so darn quick that the music that plays when the levels load in Turrican 2 only plays the first couple of notes and that's it, because then the level loads. Its a weird complaint, but I really loved how that music built the tension back in the day.
Otherwise, colour me impressed.
