PS2 Open PS2 Loader v1.1.0

[SanjoXJ218]

@SanjoXJ218 None PS2 model have 100% game compatibility with PSX game played via PS1DRV. Worst have Deckard models (SCPH-75K and newer). POPS/POPStarter are emulators so they have far way lowest compatibility, but Hugopocked made many patches which makes before problematic games now fully playable.

In case of USB, slowing down or stuttering isn't fault of USB v1.1 because that's twice faster than PSX ODD. You experience incompatibility issues, or your disc images are fragmented; or Your USB is slow as turtle, slower than PSX drive.

Oh, think you for the clarification on all those points, Berion. Yeah, disc images being fragmented or outright corrupted is definitely an issue. I already know by now that there are a handful or so games on the PS1 that regardless of model, do not work on PS2 (or at least have framerate or display issues here and there): several of them being Grand Turismo 2, Armored Core: Master of Arena, Mortal Kombat Trilogy, Tomba!, Street Fighter Alpha 2, Harvest Moon: Back to nature, Digimon Rumble Arena, Formula one '99 and Final Doom.

Defragmantation from what I remember is only required with DKWDRV.

Spoiler: Other issues

Unfortunately for now with this homebrew in many FMVs there is no audio and there is no CDDA support.
So in short audio issues.

You really have to have an old USB drive (USB 1.0?!) to experience bandwidth bootleneck.
Additionally these drives have in many scenarios less than 1 GB, so you even will not be able to put a game image on that device.
If the USB drive has at least v2.0 there should not been any data speed issues with PS1 games.

Since all these games have different (compatibility) problems it does not matter from which device they are being played.
For example in Gran Turismo there are black cars if you launch this game with POPStarter through HDD, SMB or USB.

File corruption should not happen because all games (images) are being loaded as read only,
at least with POPStarter (2019/06/05).

Armored Core Master of Arena, Tomba, Street Fighter Alpha 2

These games work well through POPStarter (2019/06/05).

Grand Turismo 2, Mortal Kombat Trilogy, Harvest Moon Back to Nature, Digimon Rumble Arena

These games have already been fixed here.

I too am wondering about this at the moment.

 

[Berion]

There are plans to reach OPL to mostly fixed state and archive it. Developers involved in it, wants focus more on Neutrino. This means that OPL dying.

But wOPL not. From news behind the scene, Krah Jolito joined to the club, along to few other people. And we preparing here and there little refactorization.

Yeah I have the stable 1.1.0 version and some PAL games don't work, show just a black screen.
