A t first the name filled me with fear because it made me think of flashing your own ROM cartridges, which is a voodoo I'm not at one with. It turns out that products like the Easyflash are less scary than they sound. I believe EF had 8 ROM slots that you could flash from the C64 itself and then it operated as a cartridge containing the ROM you selected. If I have that wrong, forgive me, but it just demonstrates that KFF is easy enough for a numpty like me to use. Creator Kim Jorgensen has taken that Easyflash idea and run with it. Kung Fu Flash takes a micro SD card, on which you put as many program files, disk or cartridge images as you like. (If you buy one from Future Was 8-bit, it comes with a micro-SD which already has a lot of stuff copied to it.) The Menu button on the KFF menu gives you a file browser. You simply select one of your .prg files to run it. In that respect it's a credible alternative to the SD2IEC. If you select a .crt file, KFF will flash that image
