Describe the issue

In OPL beta version 1.2.0-2163, every time I load a game, it just goes to a black screen. I've tried the compatibility modes and they don't work, can someone please help me? Updates: In addition to not being able to run Metal Gear Solid 2: Sons of Liberty, OPL corrupts my pendrive.

Console model

SCPH-77001

OPL version / revision

OPL beta 1.2.0-2119

Context and extra information

Resident Evil 4 [SLES_537.02]:

OPL Stable 1.1.0 USB - works well

OPL Beta 1.2.0 2125 USB - works well

My PS2 model is SCPH-90008. I use redump images and don't use PADEMU, VMC, GSM.

@Vini182837 this game is not compatible with VMC and PADEMU.

Sometimes issues like this happen when USB device is not fully compatible. I mean OPL can show game list but it will always crash\freeze after debug colors. To be honest I am not sure why? Sometimes one of my flashrive works with SCPH-70004, but it refuses to work with SCPH-77004... Sometimes it shows games list, unfortunately none of the games can be loaded...

So the best option will be to check other USB devices because a compatibility is not ideal.

Actually it probably is the same issue as with multiple usb devices: "too fast initialization". If usb device is slow, then sometimes it can lead to similar behaviour. Should be fixed in https://github.com/ps2homebrew/Open-PS2-Loader/pull/1443

Is there any initialization differences between IOP (e.g. SCPH-70004) and DECKARD (e.g. SCPH-77004) consoles?

No matter what I cannot launch any game with this flashdrive on SCPH-77004 even on OPL 2197, However everything is fine with SCPH-70004.

Deckard requires more power. That means that usb takes longer to be detected. Opl waits 5 seconds, maybe it is not enough.

Is there a chance to test a version with a higher delay? I mean 6s, 7s, 8s ,9s?

I recently tried BDM Assault to use these drivers with FreeMcBoot 1.966.

In short how to use it:

bdm_assault.irx must be pasted into mc?:/SYS-CONF/USBD.IRX usbd_bd_assault.irx must be pasted into mc?:/SYS-CONF/USBHDFSD.IRX

The funny thing is that now I can boot a console with a flashdrive, launch OPL and in most causes everything is fine. Previously to get the best results I needed to put my flashdrive after OPL boots to get the best compatibility.

So I do not know if FMCB is not conflicting\colliding with OPL drivers in some way?
