I previously use in vice emulator with success, but now i restored my C64G (Germany version of 1988 bought) and try to load on the Kung-fu flash cartridge but i only see the loading... screen without end of that. 

I also have SD2IEC and same happen on that without loading of the Aviator 2 file (Aviator 1 is good and load) i read the other thread on that trouble without solution.

For that without losing time, it is possible to add an official CRT version on the download with the D64 file?

Thanks.
