This is to address the issues I observed in the new video posted by
@wingedmerchantgaming.
First off, get yourself to a car parts store and get a cheap little packet of silicone grease, they sell them at the counter and usually are called 'Spark Plug Boot Grease' here in the US, or also it can be called 'Dielectric Grease'. One packet is more than enough for 1000+ applications to your DPAD/buttons. Use a toothpick to dab a small amount around all the edges of the DPAD, work the DPAD to get it in there and wipe off the excess. Your DPAD will loosen up with time and not squeak as much. Reapply occasionally.
The game Driver (E) [SLES-01816] should work fine, it loads and seems to work just fine for me, using the scph1001.bin ROM. If you use HLE emulated BIOS, it will hang on initial screen but this does not seem to be your issue. I suspect that either
@wingedmerchantgaming has a corrupted .BIN of Driver, or that his memcards in ~/.pcsx4all/memcards/ got corrupted somehow, as your game seems to hang when accessing memcards. You could try removing or renaming the files in ~/.pcsx4all/memcards/ so new memcard images will be created, but all saves will be lost if you delete them. The md5sum for my .BIN of Driver is 9d77cf2610e29c4ada694784275cef5e if you want to compare the integrity of your binary against mine.
If you own them, and are a native English speaker, I would suggest you use NTSC (U) versions of games, as their framerate and vertical resolution exactly matches that of our device. An additional benefit is more games will work without needing to provide .SBI/.sub subchannel files to bypass the copy protection of many later European PAL games.
As for your issues you had after swapping the SD card, I cannot help you as much as I do not use the OpkManager program. The problem seems to be that you initially installed the .OPK to your external SD card, so of course it no longer can be used once you swap the SD for another. Then, I believe you never inserted the first SD card back into the device while attempting to correct the issue. You should focus on sorting this out and I recommend you do not install emulator OPKs to external SD cards to avoid these issues. Insert the SD card you originally installed the OPK to, and uninstall it through OpkManager. Then reboot, and once you are sure it is uninstalled from any and all memory devices, install the pcsx4all OPK to your internal NAND memory and keep it there.
If you want to improve sound fidelity, referring to your mention of sound in Dino Crisis, you could try setting Interpolation to 'simple', as that has minimal impact on performance and actually sounds the best to me. Or, play with a decent set of headphones when doing personal gaming as the speakers aren't exactly hi-fidelity.
For issue of settings not being saved, the emu does not save the settings until the emulator is exited through main menu. This is not ideal, because if a game hangs like Driver did and you use Power+Select to exit you will not see the settings have been saved next time around. So, that is a real issue.
