tapecart - a tape port storage pod for the C64
tapecart that adds SD card support using the Tapuino hardware. TCRT and PRG files can be loaded using the Tapecart SD Browser (browser.prg) which should be placed in the root directory of the SD card.
 
Tapecart SD is not intended as a replacement for the Tapuino firmware, as there are no support for buttons and display or using TAP files. Ideally, I would have preferred to use the original hardware and just replaced the SPI flash with a SD card reader. However, the program flash in the microcontroller is too small for the FatFs library.
Flash and loader write commands are not supported.
