Describe the issue

Hello.

If the skip bios logo option is disabled:
The first game I launch works fine, but the second one freezes the entire Retroarch.
You absolutely need Alt + Del + Ctrl and kill process.

I've tried various combinations of games in the NTSC USA RZV format, but it's always the same.

If the skip bios logo option is enabled, everything seems to work fine.

The core is updated to the latest version, and the Dolphin emu files are also freshly downloaded.

Edit:
I'm 99.9% sure I've found the reason for this error.
If you run a game that has "Dual Core Mode Off" saved (.cfg file in RA's config), then shut it down and run another game that has "Dual Core Mode On" set by default, it completely freezes the entire Retroach system.

It seems that the skip bios logo has no effect here. And RA only freezes because of dual core mode.

Unfortunately, dual core mode off is required for some games, such as Luigi's Mansion, which has graphical artifacts in dual core mode.
