Yeah I agree Internal is fastest oh but for your other questions, well the latest version of opl is 0.9 r590 beta, try searching up with those words, if not i can upload for you if it was clear where to upload on psx-scene:mad::mad::mad: , now for you first question between opl 0.8 and opl 0.9, some more game compatibilities, now acess to play dvd9 games on dual layer, faster loading from hard drive (internal or external). For the releash of opl 0.9 well we are at 590 out of like 1000 so it will probably be one of the last versions.
For cutting games tere has actually been a new thread, it's a new loader developped by this dude, it's something like ps2 eldsf or something please someone correct me. Anyways it's new to make no more/least amount of video chops in game however much more work will need to be done to get a game compatibility and gameplay as opl.
The actual version is R637...
