PS2 OPL Error 300 on Pi4

[ja50nR0mAn]

Has anyone actually managed to get this working on a Pi4? I have tried some of the fixes suggested in the Issues section such as modifiying smb.conf but nothing works. This works perfectly on the Pi3B+ with the pre-supplied image.

I installed Raspberry Pi OS with desktop on a Pi4, followed all instructions and am able to see and access the contents of the share folder on a PC. My PS2 should be configured correctly as the Network Settings are simple and I can get this to work on Pi3B+. Still get Error 300 on Pi 4 and feel like I have tried everything. Used uppercase and lowercase characters, entered Guest username, and still no luck.

Any ideas as to how this can be fixed?

@ja50nR0mAn Try renaming your usb to nothing, just a blank name. If that doesn't work, try the latest version of OPL from here: https://github.com/ps2homebrew/Open-PS2-Loader/releases
