Really simple question

Those PSX ISOs you download that are all split up into smaller files, is it necessary to merge them all into one file, or can you just put them all in the same folder and leave it at that?Sorry for the stupid question.

that depends on how they are split. If they are a multipart rar file, then the will be automatically combined when you extract the contents. If you mean the .cue/.bin/.ccd/.sub files you get out of many of our self-extracting archives, then they just need to be all together in the same folder.

Alright, thank you for clearing that up for me.
