Yes, if you have version 1 firmware or later. If you have version 0 firmware then it has to be upgraded to support this mode. (You can display your firmware version by doing: mb -s ) Upgrades are not physically possible over the parallel port or serial ports. In order for the MBV2 to transmit serial data out the pin 9 serial connector, pin 7 must be held high (+5v to +12v). (However, the MBV2 can receive data without requiring anything to be held high.) This is normally accomplished by enabling hardware handshaking on a PC serial interface. This upgrade supports standard UART transmit/receive and hardware handshaking from PC->GBA. (i.e. GBA can wait until PC is ready to accept data.) Handshaking from GBA->PC is not supported due to hardware limitations. (i.e. PC will not wait until GBA is ready. It can send data to GBA at any time.) To upgrade the firmware you must send it to the following address along with US$5 to cover return international postage: Jeff Frohwein 910 Clinton Ave.
