(PCE) Gradius

A conversion from the classic Konami’s horizontal shoot’em up, released in 1991 on PC Engine.
Gradius introduced the cycling power-up system : some enemies release a pod after being destroyed and these pods can be used to upgrade the speed of the ship or new weapons, from double shooting to laser and missiles; the upgrades are showed in order on the bottom of the screen, from speed-up to option, and each time the player collects a pod an upgrade is highlighted, if it’s not selected when another pod is collected the following one will be highlighted.
A good porting but some slowdowns could annoy who looks for a perfect conversion.
Released only in Japan.
