Papilio-Master-System is a recreation of the Sega Master System on a FPGA. Three compiled versions are provided : 1) sms_vga_final.bit, for use with a 8 color VGA output wing 2) sms_tv_final.bit, for use with a TV wing, producing NTSC signal 3) sms_megawing_final.bit, for use with a megawing. The wings layout for sms_vga and sms_tv are as follow: AL: joystick wing (note: you'll need a two button joystick) AH: VGA wing (for the sms_vga version) BL: micro SD wing (optional, see note on the megawing version) BH: audio wing CL: free (reserved for the to-be-implemented second joystick port) CH: TV wing (for the sms_tv version) Note: The Megawing version will provide the best image, but you'll have to upload the rom to the SRAM chip through USB (see my modified version of papilio-prog). The two other versions can read the rom files from a FAT16 formatted SD card.
