C64 Sprites, XC-BASIC3, ugBASIC, and Start Coding Commodore PET!


Lots happening on the online retro IDE lately.

Firstly I added a new platform, the Commodore PET.

You might also notice Atari, Spectrum, and C64 platforms now have ugBASIC with more to come, and the Commodore systems also have XC-BASIC3!

These compilers are also featured in my exploration of sprites and bitmap graphics on the C64 you will find linked below.
