Veramente una simpatica idea, inserire una versione homebrew ‘fatta in casa’ dell’interfaccia SD2IEC dentro il contenitore di vecchie cassette magnetiche.

SJLOAD is a C64/C64DTV software fastloader. Its main difference from normal fastloaders is that it only works with Jiffy-enabled drives and uses the Jiffy protocol. This makes it handy for people who have a Jiffy-enabled drive (also new hardware such as SD2IEC) but do not want to make the hardware changes necessary for exchanging the C64 kernal.
SJLOAD speed is a bit higher than normal Jiffy since SJLOAD uses the same protocol but a different implementation (it disables the VICII during load etc.). With an SD2IEC, SJLOAD is about 15% faster than a normal Jiffy kernal.
SJLOAD is loosely based on VDOS (1986) by Edward Carroll. However, the fast loading routines have been replaced completely by 1570.
