Jonas Hultén made it possible to see one of my favourite Atari 2600 games on the VIC-20.
In case you have been trapped in a mine all this time, in H.E.R.O., your mission is to rescue trapped miners from underground caves. There are 20 levels to play, and you will be considered a professional hero after these 20 levels. For the real hardcore players, the game ends when you reach one million points.
Jonas started the conversion in February 2022. He wanted to attempt to make a smooth action game for the VIC-20 and thought it would be possible to make a software sprite port since the original game was so simple. Initially aimed for a 24 KiB expanded machine, the game ended up with a demanding 32 KiB expansion requirement. Maybe this is a problem to run on some real VIC-20, but if you prefer an emulator, any memory requirement can be met easily.
You can download the game for free at the author’s website.
