It's been possible for a bit to convert any PSP game into PSP Remasters, so, here's a tutorial on how to. I haven't tested if it goes to 1080p, but so far I've been able to play them in 720p which is nice, and the bright side about doing this is that the PS3 plays PSP natively so there isn't any slowdown.
This tutorial is written with the assumption you are using your own backups, and thus, if you have any issues with EBOOT issues and .ELF, this is meaning you have a patched ISO and you need to redump a fresh copy of your backup for it to work.
I went ahead and took the liberty of taking a screenshot of Maverick Hunter X in 720p with my capture card. Here's how it'd look without HD.
Here's it with HD on a PS3
Enjoy.
