Platform: Commodore Vic 20
A short entry which we will try and flesh out soon. Mario Bros was listed as being due for release for the Commodore Vic 20 over at https://www.digitpress.com/faq/atarisoft.htm – though was cancelled either due to the dying Vic 20 market or the collapse of Atarisoft.
On the site, it has a note from Jim Huey to say that it was in development.
If you know anything more about it – please do get in touch with us.
With thanks to Fabrizio Bartoloni for the heads up.
