PROBLEMEXPOSITION

It's not alway easy to get VIC-20 games to work due to its different configurations. This article tries to give some hints what you can try to run them.

SOLUTION

To run VIC-20 games, try one or more of the following:

• Try to autorun with different memory sets: "no expansion", "3K" and "Full"
• Load the file in a hex editor and have a look at the first two bytes. If they are e.g. 00 A0 the file should probably be attached as a cartridge image at $A000.
• Some Scott Adams text adventures need "special" handling: (taken from http://members.nbci.com/vic20/adams.html):
  • Use full memory expansion and "Virtual Device Traps" (which is the default).
  • POKE44,16:POKE56,30:POKE4096,0:new
  • POKE648,30 (hit Runstop/Restore which is Esc/PgUp in WinVICE)
  • LOAD"4.Voodoo Castle",8,1
  • SYS32592
