Title: TinyASM
Platform: Commodore Unexpanded VIC-20

Video: PAL/NTSC
Software type: Assembler / code editor
Written by: Henner Kessler
Release date: January 2025
Language used: Assembler



Description:
TINYASM is probably more of a code editor than an assembler for the VIC20. It can be loaded directly from disk without a module or memory expansion (and it wouldn't work with a memory extension).

Your program can use any RAM position between $18a7 and $1dff and be 1368 bytes in size (max).
Vers. 1.1 includes also an TAPE version. Here you can use any address beween $1973 to $1dff.
You can also save and load it to/from disk (or tape) and start it with the appropriate SYS command.
The zero page can be used between $01 - $36. All other memory areas are in use.

The editor is very simple but good enough for coding.
Note: Only hex values are allowed (like $01 or $1c00)

The entered code starts with F1-key.

a quick overview of all functions
.D - delete line
.I$0a - insert 10 Bytes (255 max)
.J$1A00 - jump to address or .J$Mn label $Mn
.L“NAME“,8 - load program (or .L“NAME“,1 in tape version)
.S“NAME“,8 - save program (or .S“NAME“,1 in tape version)
.B - switches between code and byte view
.T“ABCD…“ - insert text
.$01$02$03... - enter bytes directly
.Mn – (simple) memory labels - it's better to watch the video for this
F1 – start your code

Everything else can be seen in the attached video.

Title: Formula V20 '81
Platform: Commodore VIC-20 +16kb memory expansion
Media: Floppy Disk / Tape
Video: PAL/NTSC
Interface: Joystick
Software Type: Arcade game - Early 1980s racing
Written by: W E de Villiers
Release Date: March 2025

Formula V20 '81 is a racing computer game for the 16k expanded Commodore Vic-20. It’s the prequel to Formula V20 '85. There are eight tracks, and the main goal is to beat the clock. Traverse each track while avoiding the competitor racing cars. There are tunnels where visibility is limited and sections where ice and sleet cover the track, which causes the player to skid wildly. Remember to catch the clocks for time extensions.
