If you don't know what this project is for, these are for bootleg units called "brick games". Let me describe what they are. "Brick games" are units that contain numerous knockoffs of various well-known games, like Tetris, Breakout, Snake, etc. These things started popping up around the early 90's and are quite popular among toy collectors and gamers looking to spend as little money as possible. The "brick game" software had its origins in China, but it is unknown who created the first model ever. The software has a 10 x 20 screen resolution, 10 blocks across 20 rows each, which is pretty weak. They are also known for their crude sound chips, which beep classic tunes, like "Little Brown Jug", "Ode to Joy" by Beethoven, etc. Not sure if so many of you know the former song. They usually have a little character in the right of the screen, that wave their arms in response to the user's gameplay. They are commonly branded with such names like "Super Mouse", "Hai Cheng", etc. "Brick game" models come in pretty much any shape and size you can think of. There used to be talking ones as well back in the 1990's that had a limited amount of phrases. Some examples include "Oh no!", "Wonderful." and "Help me." The last one is usually used when you lose a game. There's some renditions of mine of various tunes heard on these things inside. Just press your number keys and any letters that spell...you know what. Wait till' the sounds are over though to treat it like a surprise!
Credit to all, except for all the companies who make these annoying "brick games".
