A new firmware for the HxC SD card floppy emulator has been released. It features some bugfixes regarding SD card handling.
The HxC floppy emulator is directly connected to the floppy bus and emulates a complete disk drive. The disks, which are emulated by the floppy emulator, are stored on a SD card.
You can download the newest version from the HxC floppy emulator homepage. If you want to order one, you can get one from Lotharek.
