Black Screen when loading via desktop shortcut 0.10.1

[zeinlikezane]

If I try running a game via a desktop/steam shortcut with the "target" being "C:\Users\x\x\mGBA\mGBA.exe" "C:\Users\x\x\x\x\Game Title.gba" OR dragging and dropping the rom file onto mgba.exe, the game will start, audio will play, but the screen is entirely black.

Emulation > Reset does not fix it, but shutting down the rom and reloading it via File > Load Rom works.
This does not occur in 0.10.0, the version I was using previously, and just tested again.

It seems to only happen to gba games, as GB/GBC games did not have the issue (though they do load with a seemingly default mgba branded sgba border before loading the game and its border, which I havent seen up until now)

I can mostly corroborate this. The only way I can get it to display properly on OpenGL driver & renderer (windows) is by launching the .exe manually with both options already set to OGL; launching through a shortcut, game launcher (playnite), or rom via filetype association OR having either option set to anything else and switching either to OGL only displays a black screen. I don't get the same behavior as OP with shutting down and reloading the rom, it has to be a cold start of the .exe with OGL already set in order to get any visuals. Can investigate when the regression happened if requested.

I'm pretty sure I can guess when the regression happened, so you don't need to poke at it. I just need to test it myself.

I'll add an oddity to this; I am able to see .gbc and .gb files, but NOT .gba games, when launched through a short cut (In this case, through a Steam Shortcut). Like otherwise reported, the same games work when launched through 0.10.0. This issue also is in the latest development build.

I have a similar bug but the workaround recommended by zeinlikezane doesn't work for me. Opening .gba files at all results in a black screen, and I have to open mGBA the program on its own and then open a .gba file before I can begin the game.
