An Atari 8-bit emulator running Atari BASIC (or a clone) is needed for this to run.
It was developed on the atari800 emulator running as an Atari 800 XL (the model I owned when I was young). The specific command I used when developing this was:
atari800 -xl -xlxe_rom ATARIXL.ROM -basic -H1 <path to this repo locally> -hreadwrite
Note that the atari800 website has information on where to get ROMs, etc.
Once the emulator opens up and you are in the BASIC interpreter you can type
ENTER "H6:SPRTRI.BAS"(H6 is the PC-newline version of H1) to load the program into memory.
Then you can type RUN to run the program or LIST to list the program.
