"Anecdotal"
The instalment juxtaposes two generations of opponents, those carried over from the home versions and those created for the occasion, and the artwork has to make them coexist without a break of style: the carried-over silhouettes are redrawn at the same scale, with the same number of values, so that none looks imported. The late-game settings leave the factories for darker interiors.
The score stands out for mobile bass lines that act as a rhythmic engine in the absence of real drums, the noise channel being reserved for impacts. The themes of the carried-over opponents are rewritten rather than transposed, so you recognise an intention without hearing a quotation, and the final piece slows down where the genre usually speeds up.
Fourth Mega Man on Game Boy in PAL form, whose European distribution stayed quieter than the North American release. The Capcom Europe cartridge is uncommon with a clean cardboard box, and the piece attracts Rockman completists looking to close the handheld run with the distinct PAL visual identity. A late arrival on the monochrome platform, with attention already shifting to the upcoming 32 bit hardware.
Memorable bosses
More ambitious, the fourth portable installment offers Robot Masters mixed across two generations and a memorable duel against Ballade, whose shots burst in a cross. Item shopping and varied weapons enrich the run-up to each fight. Polished staging and better-judged difficulty make it one of the series' peaks on the console.
Is Mega Man IV still worth playing in 2026?
The first Game Boy Mega Man to feature original Robot Masters rather than recycle NES ones, this fourth portable entry finds its own identity. Eddie's item shop adds a welcome strategic layer, the presentation outshines earlier outings and the scrolling stays smooth. The difficulty is better calibrated, which makes the experience friendlier for anyone trying the portable line for the first time. Without quite matching V, it remains an excellent Mega Man and still a fine pick today for fans of precise 2D action platforming.
