* Added XMU Settings to the Input Screen * Added Peripherals to config * Prevent overwriting existing XMUs * Added blockdev.h to try to fix the MacOS build * Fixed some issues that antangelo pointed out * Moved the peripheralType and param vars into the loop * Moved fatx.h and fatx.c to ui\thirdparty\fatx * Added Validation for Peripheral Settings * Fixed some nits that were pointed out * don't pass NULL into xemu_settings_set_string * Changes following Matt's recommendations * Changes to XMU FilePicker * XMU image auto-bind logic refactor * renamed peripheralType to peripheral_type * removed unnecessary calls to g_strdup_printf and g_free * Cleaned up some comments, removed an unnecessary variable * handle overwrite prompt in Windows * Fixed some code format and style inconsistencies * More formatting fixes * Fixed a few memory leaks * qemu_access: check for Read and Write access * Run clang-format * Remove unused xemu_new_xmu declaration * Fix use after free in rebind code
