SDCARD! Finally an almost correct initialization.

On first row onto the screen we can see the initialization commands prefixed by ">" character.

We can see CMD0, CMD59, CMD8, ACMD41, CMD16 and finally CMD17 (READ_SECTOR).

The data is written onto sdcard starting from sector 0 using a sector-editor, in order to avoid (by now) FAT routines implementation.

The screen shows on second row the data from 0x0100 to 0x01FF (256 bytes) of SEGA BASIC Cart.
