I added my rom, deleted the original GB Studio demo rom, and renamed my rom to game.gb
I have followed to Video linked above. I exported into the same folder as the template...and the dll file is there. It loads and plays the ROM just fine when I preview the project in Godot, but the .exe file doesn't work.
I have tried on 3 different machines. Same result. I am using Godot 4.4 which prompts me to update the template project with this

I have done both "restart and upgrade" and "cancel" but it doesn't seem to change the outcome.
