How to play on desktop Linux:

• Add the game as a non-Steam game within Steam
• Install Glorious Eggroll and set it as the compatibility tool in the game’s properties
• On first launch it will prompt to install .NET 6.0 - go ahead and download it to the same directory
• Open the game’s properties in Steam and change the path to the .NET installer then run and install it
• Change the path back to the game’s EXE and it will play

Just started playing as well and was in time for the recent free week of omega and then topped up with the black Friday sale

NES: Super Mario Bros 1 and 3, TMNT 2, Galaga and Contra (with Konami code)

SMB1 was my first game ever

Last 2 I played with my dad while friends played SMB3 and TMNT
