So i have seen lots of people ask how to fix this, i used to be one of them and all the things i tried to do didn't work, until one day i found a way.


Note: Just use Open_AGB_Firm (Also in UU)
Its just a way better way t play gba games with real hardware.
Found here: https://github.com/profi200/open_agb_firm




1# Open the Universal-Updater. if you don't have it, get it here or scan this with FBI

2# Search "gba runner" and press a on it.

3# Scroll down until you see "[twlmenu] GBARunner2_arm7dldi_3ds.nds"

4# Now press a twice to install it.

5# It should be working now.


edit: oh wow why are people seeing this?

If one doesn't want to get the GBARunner2 build from UU (the one bundled with TWLMenu++ supports both hicode and DSP), then alternatively, one can use TWPatch (also from UU) and turn on GPU scaling.
A better alternative would be to use either VC injects or Open_AGB_FIRM (or mGBA, if you're on N3DS).
