sapphire is the definitive PCE tech-demo par excellence. but there're better shmups out there in terms of gameplay (GoT, WoT, Spriggan..). but anyway and beside of that, sapphire is one of my favorite shmups of all time, simply because it's just pure fun to see for what our so beloved system is capable and still can deal even with shmups on 32-bit systems in terms of action, dynamic and special effects.
seriously, all what we can gaze on sapphire was theoratically already possible on the core anno '87, in technical point of view, by side of the hucard-size which was to small at that time. the arcade card can handel 2MB of data, this makes a comparable 16-bit module. so for exapmle, if we put each level separately on a 20Mbit (street figher ce) hucard, we would be able to play sapphire (without T's music of course) on the first white core from '87 without any cut-backs in grafical and technical issues, i'm right? please correct me if i'm wrong with this theory
