After reading about Sivak Games's Battle Kid: Fortress of Peril, the homebrew Mega Man-esque game releasing for NES next month (trailer, demo ROM ), I checked RetroZone to see if the online shop is taking preorders and discovered another neat NES cartridge that I wish I knew about weeks ago.

RetroZone's 8-Bit Xmas 2009 cart features a four-player homebrew game called Snowball Fight, which is pretty straightforward: throw as many snowballs at your friends as you can before the time runs out. What really separates this from traditional NES cartridges, though, are the LEDs installed in the clear shell and the option to add in-game custom text messages/player names.

Ordering one of the personalized carts will run you around $48 before shipping ($43 without the messages). The package includes a black dust sleeve for the cartridge and a printed Christmas card with a pin-up style cover. Though December 25th is already past, Retrozone is still taking preorders until the 31st. You can also download a free ROM for Snowball Fight from 8-Bit Xmas 2009's product page.
