What everyone else is saying is correct.
what is the w.wh.orph file next to the the bios??
i have everything but that.
is that important?
It's a folder that is part of the emulator, it's usually a hidden file. Ignore it & everything that hasn't been mentioned specifically in the help so far.
i am trying to download these on my card.
prior and ater all the games are downloaded they are either rar or 7z files.
where or how do i get the proper ending files i need?
.rar and 7z or .zip files are COMPRESSED to make them smaller. When you decompress ('Unzip' 'Unrar' etc) them on your computer (not on the Pandora) they return to their original size and format. When they have been decompressed you will see what they really are, it may be that they are then Iso or Bin/Cue files.
They are no use on the Pandora until you have extracted their contents on your computer.
People tend to create these single compressed files because they are then smaller for downloading.
If they still aren't in a suitable disc image format once you've extracted them on your computer, there's nothing you can do - whoever created them didn't use a format that's suitable for you. From what you've said so far it sounds as though the emulator is working, it's just a matter of using suitable disc images.
It's also true what others are saying about talking about where you get the disc images, it's best not to mention that, for legal reasons - not for your sake, for this site's sake.
Most of us are creating our own disc images from our own Playstation discs - this means we have control over what format the files are, so our games will almost always work. All my games are in .bin/.cue - other people are also using .iso
If you're sourcing your games from 'elsewhere' you are getting games that may not have been saved in a suitable format.
Metal Slug X,
the game was a .bin and put in with pcsx.
the game appears after i navigate to it with the pcsx interface.
the game appears in hot blue font which i was told was correct to see.
once i B button it [try to open it] i get a message on the bottom saying it is an unsupported file.
If the game is .Bin (and NOT a .bin.ecm as Prometheus mentioned) then it should also have a '.cue' file with the same name with it - that's why people refer to .Bin/.Cue - it's TWO files, one big (.Bin) and one small (.cue). If there is no .cue file then it is incomplete or still a compressed file as Prometheus said.
When you have a game with .Bin and .Cue files (both will have exactly the same file name) on your SD card, you select the .bin one to start it.
If the game is in two files, for example:
MetalSlug.bin
MetalSlug.cue
and both files are together on the SD card, and you run the 'MetalSlug.bin' file but still get an error message, then it's almost certainly a corrupt file. The emulator is working, the disc image is not, time to try a different one.
how in the heck do i find .iso games??
.bin no good
.zip no good
.7z no good
.Bin/.Cue are probably the most compatible. It has to be BOTH files not just a .bin one.
.zip .rar or .7z extension doesn't tell you what files are contained inside - they may well contain suitable .iso or .bin/.cue files when they have been extracted, you just have to do this on your computer first to find out what they are. You then put the extracted files, NOT the .7z / .zip or .rar ones on the Pandora if they turn out to be suitable.
