Konami brought Gradius III to the Super Famicom in December 1990, about a year after the arcade release, reaching North America in 1991. The coin-op is notorious for its punishing difficulty, and this conversion is noticeably gentler. Parts of the stage list are trimmed and rearranged, including the loss of the arcade's 3D cave section, while the bubble-filled second stage and the Moai fortress survive.
The Power Meter is the heart of the game: capsules move a highlight along the bar, and you cash it in for speed, missiles, doubles, lasers, Options or shields. Four preset loadouts and a Weapon Edit mode decide which variant sits in each slot. It is also remembered for heavy slowdown when enemies crowd the screen, which some players treat as a built-in easy mode.
Tips for Gradius III
Pause and enter Up, Up, Down, Down, L, R, L, R, B, A for full power; using Left and Right in place of L and R blows up your ship instead.
Two or three Speed Ups are usually plenty; more makes the ship hard to steer in narrow caverns.
Dying strips most upgrades, so rebuild Options before crowded sections.
