Work on flycast had been resumed thanks to flyinghead support. Memleaks got solved thus a lot of games won't crash anymore. Some improvements at texture handling had been done too reducing memory usage and fastening texture uploads. A first PoC public build may come "soon".
Flycast compatibility list is already up and being populated by testers with debug builds available on Vita Nuova discord server. https://flycast.rinnegatamante.it The first public release will come as soon as two major issues will be solved in RetroArch frontend.
