@voljega Totally correct, the same for me... Spending 90% of my spare time collecting, scrapping and organizing games, 9 % of my time just looking at recalbox running and 1% of my times playing... (and always the same game, otherwise it wouldn't be fun XD )
PC Enigne, MSX, MAME and so on, are well known system, everyone knows.
Google will return thousands of sites talking about those machines, with tons of information and... list of games!
If you don't even know what's MAME or what's a PC Engine, I'm seriously wondering what you're doing with a Recalbox.
There is news about the runnability of TIC-80. In the meantime, there is a libretro core. Maybe there is still the possibility to implement this? Even after two years, I have not given up my hopes. 😄
