This tool allows you to create MRQ files for the Jaguar SD. An MRQ contains box art, a screen shot and details about the publisher, developer and year of release of a game.
Usage: png2mrq.exe [switches] Switches -- -box : Box art PNG, 88x124, 24bit colour -screen : Screen shot PNG, 88x56, 24bit colour -title : Game title, max 48 characters -dev : Developer, max 24 characters -pub : Publisher, max 24 characters -year : Year, max 4 characters -out : Optional output marquee filename -load : Optional custom load, loadaddr,execaddr hex -eeprom : Optional EEPROM size, 0:128, 1:256/512, 2:1024/2048 bytes -pngdir : Optional directory for PNG files -mrqdir : Optional directory for output MRQ files
To create an MRQ, specify the game details as switches to the png2mrq program along with accompanying box art and screenshot PNG files.
The box art must be supplied as a 88 x 124 pixel 24bit colour PNG file and the screen shot as an 88 x 56 pixel 24bit colour PNG file.
To use an MRQ, place it in the same directory as the game ROM with the same filename, but with the .MRQ file extension.
Only specify the optional parameters such size of the EEPROM or absolute load address if you know what they are. These values will only be used for homebrew software and otherwise should not be set.
