This so far is the best popstation converter I've used, so you should try to reference it into your material. It uses a ripped E-boot that only contains whats needed, so it means less space taken up by the thing as a whole. It also hex edits the E-boots for you by just finding the game you're converting, and clicking on the title. And last but not least, it can smack images onto your eboots.
(However, it still uses the hotshots golf 2 eboot, its just that all the content was ripped out of it except for the much needed ps1 emu files.)
