Where do I get game ROMs for use with CCS64?
You don’t. ROM stands for Read Only Memory and is normally the basic part of a computers operating system (BIOS). The ROM is an integrated electronic circuit and is located on the computers motherboard, and on expansion cartridges. Games for C64 were most often distributed as 5 1/4″ disks or on tapes, as most C64 systems were connected to a 1541 diskdrive or a C2N cassette recorder. In CCS64 are instead disk images and tape images used, as the original media can not be used directly. They are available at the Internet in very large quantities, a good starter is www.c64.com . You should really start reading the user manuals and other useful papers for C64. There are a lot of literature available at the Internet, search for “Project 64”.
