VIC-20 Unexpanded Adventures
A downloadable game
VIC-20 Unexpanded Adventures is a collection of two text adventures for unexpanded VIC-20 (plus Commodore 64 and Commodore 16 versions).
Pursuing Tom Ram
Dark text adventure for adults where you have to explore the house of Tom Ram, suspected of kidnapping children.
Desert
Grid game where you are lost in the desert. Try to reach the city of Al-Jadur without dying of thirst and avoiding the dangers of the desert.
Desert includes Superdesert, a harder mode for the masters of the desert.
Both adventures are in PRG format. Drag and drop them over VICE emulator to play. Each game has a manual with the main commands and some extra help if you need it.
Games are free. Support Knowledge.
Both adventures have been programmed in assembler. The source code for the games (including C-64 ports), are on Epic Adventures' Github.
In addition, we have written one guide for each game explaining the design decisions and source code. You can learn what we learnt doing these games and create your own adventures for 6502 computers. It's easier than tou think.

I am interested in Pursuing Tom Ram for the VIC-20. The C16 and C64 versions work, but the VIC-20 version does not work. I'm using WinVICE. I've tried drag and drop to the emulator, autostart from within the emulator, copying the prg to a disk image and autostarting that, and loading the disk image and LOAD"PURSUING TOM RAM",8 all without success. Is this a buggy prg file or is there an extra undocumented SYSxxxx step?
Dear Garry, thank you very much for your feedback.
I have downloaded the zip file, and dragged and dropped the VIC-20 version of Pursuing... into my Vice 3.8.
It works fine.
My configuration is VIC20 PAL with no memory expansion (probably, the default VICE configuration). Maybe you use a memory expansion? It only works on an unexpanded VIC-20.
I have created a new version of the PRG for VIC-20 (tested with the same VICE too ). It's in the github repo (link below). It should be the same as the PRG in the ZIP, but who knows.
If you can send me more info I'll be happy to try other things.

It was the memory expansion. I had it set to full by default, as this seems to work for just about everything. If I change it to no memory expansion, it works. I'm not a VIC expert, so I thought it would just ignore the extra memory in the memory expansion, but apparently not. Anyway, it works now. Thanks for the help.
As a fun experiment in VIC memory maps, you can try this game with a +3k expansion and it should work, but not with +8 or larger. That's because the memory map moves when a +8 or larger expansion is added.
Hi arnstar.
Unfortunately the games in the pack do not work with a 3 Kb expansion. I tried to run them before writing this reply. I'll explain why I think this happens.
At the beginning of each game there is a small BASIC loader (a SYS instruction) and if that instruction is not right at the beginning of the memory, it doesn't work. You can find the source code in our github repo if you are interested.
Excellent I was looking for a simple desert survival simulator. Set in West Texas, but close enough!
Thank you very mucho. Hope you enjoy it.
