Keyboard and mouse controls will now work if you use the kbMouseSupport parameter in the config for Libretro cores. Be aware that capturing mouse and keyboard controls properly is only possible in fullscreen mode. Note: In the case of DOSBox, a virtual filesystem handler is not yet implemented, thus each game state will be shared between all rooms (DOS game instances) of CloudRetro.
