i have a repository on github that allowed for downloading ports of my games for muos and batocerra, but these builds were made when muos was not running on aarch64 and before other changes got implemented.
This evening i spend time redoing the build script and packaging so that all those (my) games work again on latest muos custom firmware.
Some of these games also exists in portmaster but not all of them.
I also added a new playdate game i did being Worm. But there also exists a Vircon32 version with colored graphics (muos has a vircon32 core)
you can grab the games from here: https://joyrider3774.github.io/rg35xx_plus_batocera_ports/
