I should also mention that creating a DVD might take more time and resources, like a blank DVD and a burner. Also, the size of the ISO could be an issue if the user doesn't have enough space on the DVD.
Wait, but with CFW, Ulaunchelf might be included automatically. I need to clarify whether Ulaunchelf is for modded PSPs without CFW. Also, the download part: the original article mentions a DVD ISO, so maybe it's distributed as a DVD image that users can burn or use via memory stick. The download method might require a torrent or a direct link, but I should check if that's up-to-date and legal.
Finally, in the conclusion, reiterate the purpose of Ulaunchelf, the benefits of using V4.12, and emphasize legal homebrew usage. Maybe include links to trusted sources where users can download the ISO safely, but I should be careful not to link to any copyrighted sites or torrent platforms directly.
