1) pops 5.00 isn't perfect. I still had to go back to 4.01 (and earlier ones... 3.71 I think works) to get proper sound in Rayman. I'm talking about the music that plays within the levels and on the map screen (where you choose your area).
2) The latest psar dumper works for all previous firmwares. the firmware must be at the root of your memory stick and named eboot.pbp. The dumped firmware will end up in /F0 when it's done.
3) drock82.. your link is broken now (either that or one of my proctective measures is keeping me from going to that domain, in which case I probably wouldn't appreciate being sent there in the first place) but I don't think you're permitted to link to copyrighted files from this website's forums anyway.
in short... we still need popsloader for maximum compatability (anyone try FFVII from 5.00 yet? post plese :D)
Thanx DAX!!
