MMC and SD cards

MMC and SD cards have been emulated in C language. The software uses a disk image file, which represents the file system. A structure is created with the card data and the disk image that represents the MMC-SD. The data from the structure is read and written via SPI. It seems good (it also implements different types of commercial cards). Unfortunately for me it is too complicated to implement in SimilIDE, however I report it in case it could interest someone.
