6510) Built-in games The official games for the unit are mostly a mix of Epyx and Hewson C64 games. Games unique to the NTSC or PAL versions are noted below. Hardware-modding Since the internal circuit board has exposed solder points for floppy-drive and keyboard ports, hardware modifications of the C64DTV are relatively simple. Known hardware mods Keyboard connector External joystick (Port 1 and 2) Floppy connector Power unit connector Fixing the palette problems of the PAL version (to some degree this is possible in software by adjusting palette entries) S-Video connector User port Original C64 casing and PS2 keyboard Additional hardware Data transfer cable (Parallel port (or USB/serial port via DTV2ser) to Joystick or user port) SD card interface 1541-III or MMC2IEC Limitations The internal flash memory is accessible as device 1. However, software is not included to support write operations so high-score saving is not possible. Also, flash devices used in the DTV are specified for a very limited number of write accesses only. When using the standard keyboard mod, the F7 key does not work. There is a workaround, the "Keyboard Twister." Software-modding The DTV contains software-flashable memory. A number of tools have been released to compile programs into DTV-compatible flash images and load it onto the DTV. People made their own game compilations, adding popular (sometimes DTV-fixed) games that were not in the original DTV, added boot menus to make homebrew software development easier or enable new features, for example transfer programs like DTVtrans for transferring data from PC to DTV RAM and vice versa via the PC parallel port (or USB) and the DTV joystick port.
