Pokemon emerald whitescreen on GBArunner3
So I've been trying for a while to get Pokemon emerald to run on my old DS Lite.
I'm using a flashcart with R4iMenu andTWiLight Menu++ as a secondary kernel, I followed this tutorial : https://sanrax.github.io/flashcart-guides/tutorials/emulators/ to install gbarunner3. I've got a legit GBA bios, I used sdFormat, I tried the implementation in TWiLight menu, I even tried to build gbarunner3 myself to see if there were any differences, nothing changes the result : the logos roll and then whitescreen. Same problem with pokemon Leaf Green.
I'm able to run lighter ROMs such as Metroid: Zero Mission though, and although I couldn't launch pokemon emerald with the tutorial installed gbarunner2, TWiLight Menu integrated gbarunner2 worked, with music synchronization problems though.
Would anyone know what I could have missed causing this whitescreen issue ?
Thanks in advance for your answers !
