Hacking Homebrew GCN Emulator Nintendont: random console freezes or weird text artefacts on startup via forwarders/injected games

[XenoFredo]

Nintendont sometimes freezes the console completely (to the point I have to pull the plug) on startup from the Wii U menu (forwarder, either Nintendont itself or the game injects), usually the first time I boot it up after turning on the console. Then after rebooting it usually always boots up and works fine. Sometimes it will boot and I'll have weird artefacts instead of legible text in the Nintendont menu.

Could you please help me identify what may be causing this? I'm using the latest version of Nintendont.
