PC-88 rolling action game Mr. Bump launches on Switch November 12

EGGCONSOLE Mr. Bump PC-8801mkIISR launches globally on the Nintendo Switch on Thursday, November 12, 2026, for $6.49 (880 yen in Japan). Ahead of tomorrow's Nintendo eShop release, publisher D4 Enterprise shared two minutes of gameplay footage showing the 1986 rolling action game's steep isometric ramps, monster hazards, and slippery ball physics in motion. D4 Enterprise first announced the Switch port earlier in November as the latest entry in its ongoing EGGCONSOLE retro computer line.

Zero brakes on an isometric cliff

Originally released in February 1986 for the NEC PC-8801mkIISR and later ported to the Sharp X1, Mr. Bump clearly takes its structural cues from Atari's 1984 arcade hit Marble Madness. The premise drops its protagonist into another dimension following a sudden crustal shift, sealing him inside a checkered "Survival Ball" that has to roll down 12 cliffside stages to get home.

There's a catch to piloting that sphere: it can't actually come to a complete stop. Heavy inertia pulls the ball downhill while you apply reverse spin to stay on narrow, guardrailless ledges, and every movement drains your energy meter. Colliding with patrolling snail-like monsters or stage traps drives up a separate damage gauge until you lose a life, though hidden passages and warp zones offer shortcuts for players brave enough to poke around the edges of an abyss.

Translating trackball momentum to 1980s computer keys was always a tall order, and I'm curious whether an analog stick tames that touchy inertia or just gives players a smoother way to fling themselves off Stage 2.

Before NCS became Masaya

Mr. Bump holds a neat spot in Japanese studio history as the very first video game developed by Nippon Computer Systems (NCS). Before jumping into computer entertainment in 1986, NCS was strictly a business software firm. The company soon established its Masaya console brand (named after founder Masaya Fujita) and spent the late 1980s and 1990s Turning out cult favorites like Langrisser, Assault Suit Leynos, Schbibinman, and the gloriously weird shooter series Cho Aniki.

NCS exited the game business in 2000, and Tokyo-based publisher Extreme acquired the full Masaya catalog in November 2014, which explains Extreme's copyright credit on the gameplay video and store listing.

Outside of original 5-inch floppy disks, the PC-8801 version has only resurfaced once before, arriving on Windows in February 2007 through D4 Enterprise's Japanese Project EGG subscription service. Tomorrow's Switch release is its first console port and its first official release in English and European storefronts (€5.59 / £5.39), though like several action-focused EGGCONSOLE ports, it omits the series' usual Scene Select mode. It's a modest 43 MB download, and $6.49 feels fair for a slice of pre-Masaya history, even if original 1986 players still remember how rudely it rolled the full staff credits every single time you got a game over.
