Atari 7800/Homebrew

The 7800 was a flop in the market place, due to when it came out and the competition. Regardless, the fan community has still kept the system alive with a number of homebrew titles. Most of the games below were done by homebrew programmer superstar Bob DeCrescenzo, aka PacManPlus.
Some of these can be purchased with PokeyOne chips for enhanced sound.
All these can be bought from Atariage. Here's a huge list of other homebrews and hacks with ROMs.
==The list==
Box Art	Title 	Genre 	Description 	Acquire
 	Baby Pac-Man 	Maze / Pinball 	Probably the most strangest Pac-Man that came out of the Bally-Midway camp when they had the license. Its a hybrid Pinball / Maze game. The top portion was a CRT with your traditional Pac-Man gameplay. While the bottom half was occupied by a small pinball playing field. Hard as balls (no pun intended), since you have to play the pinball portion to get power pellets. Never ported to any home system due to its nature.
Long thought to be impossible to properly re-create on a home console, PacManPlus ported the game over with amazing results. He also included additional options to make the game easier. Such as changing the behavior of the ghosts to match the other Pac-Man games and just playing the pinball or maze portion alone.	Commercial
ROM
 	b*nQ 	Puzzle / Platformer	A port of Q*Bert to the 7800. includes multiple difficulty levels and is near arcade perfect. 	Commercial
ROM
 	Dungeon Stalker 	Shooter 	A homebrew title based on Night Stalker on the Intellivision. Basically Mattel's take on Wizard of Wor. A survival game, where you have to kill enemies and stay alive as long as possible. The catch is you have limited ammo and it spawn randomly on the map. This version ditches the robots for medieval fantasy enemies. 	Commercial
ROM
 	Frenzy 	Shooter 	The sequel to the beloved 2600 and Arcade game Berzerk, that never seems to get the love it deserves. Frenzy adds more defined map and enemy types, walls that you can bounce your shots off of, and you can kill Evil Otto! Pretty much arcade perfect with the voices intact. Includes 2 player Head-to-head and Co-Op modes. Also includes Berzerk, given the same love as the Frenzy port.	Commercial
ROM
 	K.C. Munchkin 	Maze 	A homebrew port of the (in)famous Odyssey 2 Pac-Man clone. Atari though it was 'too close' to Pac-Man and sued Philips. They were forced to halt sales of the game. They eventually redesigned the game and re-released it as "K.C.'s Crazy Chase". 
Includes the maze editor that was included in the original. 	Commercial
ROM
 	Pac-Man Collection	Maze 	A collection including Pac-Man and Ms. Pac-Man. Ms. Pac-Man has an official port to the 7800. But this collection includes a number of semi-official mods that have never gotten major releases (Fast and Plus). Also includes different maze variations.
Really good ports of Crazy Otto, Jr. Pac-Man, and Super Pac-Man are also available for the system. 	Commercial
ROM
 	Scramble 	Horizonal Shooter 	A damn-near arcade perfect port of Scramble, TIA-generated 2600 sound effects notwithstanding. It really demonstrates the hidden potential of the 7800. 	Commercial
ROM
 	Space Invaders 	Shoot Em Up 	Pretty much arcade perfect port of the classic. Plus it includes all the optional modes from the 2600 port (Invisible Invaders, Moving Shields, etc.). 	Commercial
