The purpose of the "Atari ROM Maker" is to convert plain ROM files (".bin", ".rom") into cartridge files (".car") within command line scripts. The resulting files will have the correct header and checksum. As a result, emulators will recognize them correctly, and you will not be prompted to choose the cartridge type every time. Unlike the interactive conversion options offered in most emulators, the command line tool can be incorporated into your build process. This allows for a single build process that creates multiple target formats. For example, you can create ".car" files for Atarimax Maxflash, SIC!, MegaCart, and others with the same script. It is open source, written in pure Java, and runs fine on Windows, Linux, and Mac OS X. The download is available here. The source code is available here.
