I am using the xmillenium - Xmil106CT T-Tune which practically plays .Tap files without any other requirements as long as the bios files are in the same folder as the emulator . now i just need a genius out there who can show me how to create a command line to launch Xmil, load the tap file and run from launchbox. At the moment i have to do manually , open the emu, select CMT and then OPEN and then locating the rom i want to play.
