Description
Description
Starting RetroArch or loading a core will hang for 15-20 seconds. This seems to be caused by loading all of the .info files in core_info_list_new, triggered from menu_driver_init. As more cores are added, this will only get slower. I only started to notice this recently, probably because of all the new cores (which I'm happy to have!)
Expected behavior
No extra delay when loading a core
Actual behavior
15-20s delay when loading the core
Steps to reproduce the bug
- Install RetroArch 3DS 1.8.5, including all core info files (I used .3dsx)
- Start RetroArch
Bisect Results
Haven't bisected since this seems to be unrelated to code changes.

Research direction
Start at core_info_list_new and its call from menu_driver_init, then reproduce the startup delay on a New Nintendo 3DS with all core .info files installed. Measure the loading path and verify that starting RetroArch or loading a core no longer incurs the reported 15–20 second delay.
