A utility by Nocash which converts a disk image to a cartridge.
The tool hasn't been tested on the GX4000, so cartridges that are created may not work on it.
In addition if you choose to convert a game that uses 128K ram ONLY (either it was made this way or a bad "crack" that needs 128K) then this will also not work on the GX4000 because it has 64k RAM.
The tool is easy for the non-programmer to use.
Technical
The created cartridge image has the OS, BASIC and Amsdos embedded in it and the data from the disk image (tracks/sectors). The image contains a patched Amsdos that reads from the cartridge rather than reading from disk.
