snowbrosj: MAME ROM Information.


Snow Bros. - Nick & Tom (c) 1990 Toaplan.

One or two players take on the roles of snowmen Nick and Tom as they battle a variety of monsters over fifty platform-based, single screen levels. The snowmen must throw snowballs at the enemies, eventually encasing them completely in snow. The encased enemies must them be kicked in order to destroy them. This is achieved by standing next to the snowball and pressing the "kick out" button, which sends the giant snowball flying around the screen, killing any enemies that lay in its path. During every 10th level, the players must face and defeat an end-of-level boss.

A number of power-ups are available, in the form of coloured potions. The power-ups are as follows :

* Yellow = Long shot

* Red = Speed up

* Blue = Bigger snowballs (encases monsters quicker)

* Green = Inflates the players like a balloon and lets them fly around the screen, killing any monsters they touch.

Released in April 1990.

Like Taito's "Liquid Kids", Snow Bros. was licensed to Manchester's Ocean Software for conversion to both the Atari ST and the Commodore Amiga home computers but, again like "Liquid Kids", Ocean decided that the game wouldn't perform well at retail and the game was cancelled. It has since been released, in its entirety, to the emulation community and is a fine conversion.

This game was released as a conversion kit only (often factory installed in a generic cabinet), so any such machine could be converted into a proper Snow Bros. machine. This title is JAMMA compatible (the circuit board for it is one of the smallest ever made, it is barely larger than a Nintendo Famicom cartridge). The marquee for this title shows a 'Snow Bros.' logo, with two snowmen, and a couple of cartoon enemies in the background - in keeping with the game's 'cute' theme.

Licensed to Romstar for USA distribution.

A bootleg of this game is known as "The Winter Bobble".

Pony Canyon / Scitron released a limited-edition soundtrack album for this game (Out Zone, Snow Bros. - PCCB-00044) on 21/10/1990.


* Killing all the monsters on a level with a single snowball causes money bonuses, worth 10,000 points, to fall down, but sometimes a glowing cake bonus will appear instead. When the cake is collected, the game stops and four blue snowball creatures appear for a short time. If these enemies are killed, they each provide a letter : S,N,O or W. Collect all four of these letters for an extra life. The glowing cake can also appear at other times during the game.

* Hidden Functions : If the 'Invulnerability dip switch' is enabled, you are invulnerable but you may also 'Pause' the game with P2 Start and restart with P1 Start.


1. Snow Bros. - Nick & Tom (1990)

3. Snow Brothers 3 - Magical Adventure (2002)


Music composed by : Osamu Ohta
