Hi, guys. Fantastic job on recalbox 4.0. All works perfect on my pi 2, only have some issues: 1. Cannot save games on the Amstrad CPC. It says "core <span class="st">does not support save states</span>". 2. On the Atari ST emulator, I can't find the SDL2 options (linear scaling and Vsync) on the Hatari screen options menu, so I cannot configure my "smooth" prefered visuals. 3. MSX games do not load (shows black screen). I tested ".rom" files that works on my PC emulator. Tried to change core machine type on retroarch to MSX1, MSX2 and MSX2+. Tried also to change core "msx.core=bluemsx" instead of "msx.core=fmsx" on recalbox.config, with no results. Would appreciate any help. Note: Any ideas on adding Commodore Amiga or C64 on next Recalbox versions?
