1. for GBFLASH is a GB/GBA cart reader based on the insidegadgets open source project GBxCart-RW. 2. for GBFLASH uses a single-chip CH579 as the main control chip, and uses a virtual serial port to drive the analog CH340 and extend it to the PC, so that the USB2.0 mission speed reaches the maximum. 3. It can back up game ROMs, backup/restore saved games, and write ROMs to supported flash carts. NOTE: 1. You can't overwrite an for Gameboy cartridge,only supports Backup or restore game saves. 2. If your game saves to an for EEPROM or Flash then it won't work on any of these clone flash carts unless you patch it to use SRAM using GBATA for example. 3. Pokemon games use a 1Mbit save and most clone carts only have 256Kbit or 512Kbit of SRAM so saving may not work properly. 4.
