- all versions
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
