In December 2020 the RVG Squad (with the help of Shallan50k to create a competition for C64 developers to develop a game that could only run in the first 4k of ram, this mean you could not use any memory above the $1000 limit, except for using the C64 I/O chips, Eg. Colour Ram, Sprites etc.

This competition would be running till the end of March 2021 :

Now the competition is nearly over, here is the last part of a 10 part development series where we develop four games for this competition, which you can see now in the entries of the competition on 🙂

I hope you have enjoyed this series, it’s the first Development Compo I have ever tried, and loved every minute of it.

In this video, we continue to take the VIC20 CLASSIC, SKRAM 20 and remaking it for the C64 in PETSCI Mode.

I hope you enjoy 🙂

This stream took place on 17th February 2021
