SD2IEC VCPU loader, 1 bit synchronized transfer
for Commodore C16, C116 and plus/4

"VL1S.PRG" <- Minimalstic fastload (KERNAL extension)

  Use like any fastloader:
      Load "VL1S.PRG"
      Start it with a RUN command
      Load the required file

  The last step may be repeated, more than one file can be
  loaded with the fastloader.

"F.PRG" <- Same as VL1S.PRG, but loads and starts the FB16
  (filebrowser for C16, C116 and plus/4) file automatically
  after start

"TPL.PRG" <- 239 blocks test file, to check loading

  When started after loading, it checks itself to see if it
  has loaded correctly.

"vl1s-source" <- Source code
