version 1.0 of COSMOS CHRONICLES using your tool available !
Question : it will not work with a ST game with 4Mo of RAM ? (because COSMOS II will be possibly use 4Mo of RAM)
The loader program stays in RAM, waiting for termination of the game to close the HATARI Emulator. If COSMOS II needs all 4MB, then you have a problem. You may change the HATARI configuration file. HATARI supports up to 14MB. Maybe this will help?
