tks for the reply. Don't thinks recalbox can run linux build without adapting. TwisterOS or raspian for the rasperry maybe Because I'm working on a theme (Mukashi) for the rapsperry system called recalbox I noticed recently the devs of recalbox included the system tic 80 that i just discovered. It is based on a libreto core but what bugs me is that extension should be
.fd .sap .k7 .m7 .rom
but most of the time I found.tic extension... that sounds more logic to me !
