In December 2020 the RVG Squad (with the help of Shallan50k https://www.youtube.com/channel/UCFjZzzJO_rXmr4FeBSf2rcQ 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 : https://itch.io/jam/the-c64-cassette-50-charity-competition

Now the competition is nearly over, here is part three 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 itch.io 🙂

In this video, we are taking the BASIC version of “Four In A Row”, and converting it into Assembly language, as the BASIC program was way to big for the competition rules. Here we also do a lot, and I mean a lot of optimisation of the code to still make it fit into the memory space.

I hope you enjoy 🙂
