Misc Need help with figuring out how to install PS2 classics placeholder and PS2 ISOs in general on PS3HEN console

[Asin]

Hello, I'm very new to this overall and I would like help in regards to installing PS2 ISOs onto my PS3 (CECH-3001a, modded with HEN, has Webman, Multiman, and Apollo Save Tools). I found the PS2 Classics Placeholder file, but I dunno how up to date it is (for example, what is a .rap file and where in heck do I put it) and I am very much feeling a bit out of my depth here. I'm hoping for someone to help explain this to me simply. Apologies if this is the wrong prefix or place, I'm just unsure what exactly to do here.

.rap files are files that are used to acquire the license when people install PS3 games.

Thank you for at least clearing up that part.
