Pokemon Gold/Silver Bugs when using Multiple mGBA Windows for Shiny Hunting

[MrMooCowAndMe]

Hey All,

I am using mGBA and ROMs I dumped from my physical cartridges to shiny hunt. I am okay with 2 mGBA windows open (1 Gold & 1 Silver), but doing 4 windows (2 of each version) or more causes some funky things to happen. Some things I have noticed are sprites glitching out and the game freezing/crashing when opening the bag.

I uninstalled mGBA and reinstalled the latest version for Windows (0.10.3) using the 64-bit installer on the website. I had no issues doing this type of thing for Fire Red/Leaf Green/Emerald and having 20+ windows open. Maybe it's because they are GBC, or I have to configure some settings? I am not sure.

Tested with Visual Boy Advance (VBA) and do not have these issues as FYI.

Also true for me (pic related)

How many distinct ROMs/save files are you using? Stuff can absolutely go sideways if you have multiple windows using the same save file.
