Abstract
Picture video signal converting/processing circuit for GBA (gameboy advance) or GBC (gameboy color), which is with the game main frame by means of a game cartridge adapter or disassembling the lower cover of the game main frame. The circuit is able to take the video signal input produced by the GBA or GBC main frame or cartridge, including pixel signal, horizontal synchronous signal (H-SYNC), vertical synchronous signal (V-SYNC), dot clock signal and audio signal. Through the command decoding of the main controlling circuit (ASIC) and in cooperation with the digital/analog signal converter (DAC), the input video signals are converted into RGB signals which are converted by the RGB encoder into video signals acceptable by all kinds of televisions. Therefore, the picture of the LCD panel of the GBA or GBC main frame can be converted and shown on the screens of various kinds of televisions. The video signals converted by the RGB encoder can be also processed by video graphic array interface card to convert and input the picture of the LCD panel of the GBA or GBC to various specifications of computer monitors.
