Kogado Studio's rare 1986 puzzle game Hercules is now on Switch

D4 Enterprise has released the 1986 PC-8801mkIISR action-puzzle game Hercules on the Nintendo Switch. The port arrived today as the latest entry in the EGGCONSOLE series. It brings Kogado Studio's block-pushing maze game to modern hardware for 880 yen.

Hercules is a top-down action game where players navigate single-screen rooms filled with hazards. The narrative setup is straightforward. The player controls a handsome warrior named Hercules who is too popular with women. This angers Lord Deus, the jealous ruler of the gods. To appease him, Hercules must survive a gauntlet of trials.

Players must collect keys and axes to open doors while dodging wandering enemies like cyclopes, gigantes, and centaurs. The game has over 40 stages of increasing complexity. Navigation relies heavily on pushing blocks, avoiding fire pits, and using springboards to jump over obstacles.

Combat is tied directly to movement. Hercules can use a dash attack to tackle monsters head-on. Managing this dash is necessary for survival in the later, more crowded rooms.

A rare mail-order original

Hercules has an unusual distribution history. When Kogado Studio finished the game in 1986, the company opted not to give it a standard retail box release. Players could only buy it through direct mail order or via the Soft Vender TAKERU system.

TAKERU was an early digital distribution network in Japan created by Brother Industries. It operated as a physical vending machine placed in computer shops. Customers selected a game on a monitor and inserted money. The machine then downloaded the game data over a phone line, wrote it onto a blank floppy disk, and printed a short manual.

This system allowed smaller developers to bypass traditional retail distribution costs. Because Hercules never sat on standard store shelves, original physical copies are exceedingly difficult to find today. The game became somewhat of a phantom release among PC-88 collectors.

Playing on modern hardware

The Switch release runs through the standard EGGCONSOLE wrapper. D4 Enterprise has been steadily porting Japanese microcomputer games to the Switch through this label. The emulation handles the unique quirks of the PC-8801mkIISR hardware, which was a dominant gaming platform in 1980s Japan.

This specific version lacks the scene select and gallery modes included in some other retro ports. It does support USB keyboards for players who want an authentic 1980s control scheme. The interface remains entirely in Japanese, though the puzzle mechanics are intuitive enough for anyone to grasp without reading the text.

Puzzle games from this era are notoriously unforgiving. Moving blocks in the wrong order can render certain stages unwinnable. A single mistake might block the only exit or trap an essential key behind an immovable wall. Anyone picking this up on the Nintendo eShop should probably be ready to hit the reset button frequently.
