I need to address the technical aspect first. Let me confirm the platforms for both games. Red Dead Redemption (2010) was for PS3 and Xbox 360, with a PSP version in 2012. RDR2 (2018) was for next-gen consoles and PC. So the PSP version is only for the first game. Therefore, the user might be mixing up the two.
Wait, maybe they're looking for an ISO file of the original Red Dead Redemption for PSP, but mistakenly wrote RDR2. Or perhaps they're confused about the platforms. I should check that. Also, downloading ISOs is usually related to pirating games, which is against the site's policies. The user's initial query might be about obtaining pirated copies, which I can't support. red dead redemption 2 psp iso download better
Another angle: the user might be looking for the best way to download the ISO, considering file size, completeness, and speed. But again, directing them to any source that provides pirated content is against policy. So the response should focus on the legal aspects and alternatives.

I should also mention that RDR2 is available on PS5, Xbox Series X|S, PS4, Xbox One, and PC through purchase from digital stores like PlayStation Store, Xbox Store, or Steam for PC. There's also the possibility of cross-generation play if they want to try the latest version. RDR2 (2018) was for next-gen consoles and PC
Next, the user might be interested in downloading an ISO, which is a disk image used for games. If they're looking to legally download RDR1 for PSP, maybe they want to play it on an emulator? But even then, there are legal issues unless they own a physical copy. I should mention the legal side here.
