My bad, i thought i would take the easy way by launching it directly from the r4 menu. Did as you instructed and now it works. Many thanks.You need to launch a GBA game using TWiLight Menu++. Open "sd:/_nds/TWiLightMenu/settings.ini", and set "GBARUNNER3_TEST" to "1". If that setting doesn't exist, add "GBARUNNER3_TEST = 1" underneath "[SRLOADER]".
When doing this, ensure "GBARunner3.nds" is placed in "sd:/_nds/TWiLightMenu/emulators/".
