Hello Chiptuners!
I use the ems 64m usb cartridge to use LSDJ in gameboys.
However, the process of connecting the cartridges to the computer is so cumbersome that they do not back up well (due to their unsigned drivers), so I lost my storage data two weeks ago.
So, is it more convenient to back up data with joey-joebags?
Joey-Joebags works just fine, as will work any other reader/flasher (Altane/Inside Gadgets are the rivals you can buy at the moment?).
That said, there is also third party program for ems 64 cart which comes with signed driver for Windows.
