I have the PS2 slim version, I really like its hergonomics, but I must admit that I would like to try the original version of the console, I think it would have less technical flaws than the slim version.
I don't know if you can insert a hard disk in the original version?but it's great that you made this post. Best regards.
The slim was nice as well, but I like the chunky one and I have had this one for about 20ish years after I bought it off my older brother.
Hard disk, is that a slot at the back for it? I think I remember a slot that was never used but didn't know what it was for 😅
