From 1da9b3806c67282f7fc2c48b5b0b4614e553c34d Mon Sep 17 00:00:00 2001 From: Raphaël Zumer Date: Sun, 8 Dec 2019 15:31:18 -0500 Subject: Hook up the GBA slot to the UI A GBA cartridge may be loaded in the same way as a DS cartridge. If the extension of the selected file is "gba", it will be treated as a GBA file. The system boot logic is still centered around the DS cartridge, so loading a GBA file will not start or reset it. --- src/libui_sdl/main.cpp | 145 ++++++++++++++++++++++++++++++++----------------- 1 file changed, 96 insertions(+), 49 deletions(-) (limited to 'src/libui_sdl') diff --git a/src/libui_sdl/main.cpp b/src/libui_sdl/main.cpp index d6aa460..68bc6b8 100644 --- a/src/libui_sdl/main.cpp +++ b/src/libui_sdl/main.cpp @@ -105,9 +105,9 @@ int EmuRunning;
