It's very possible that the C&C image is Pal, however, I always thought that it would player slower on a US system, not faster.
Odd indeed, but you could always try another download.
As for the PS1 save, it's a different format in Pops than on the card. You can copy the file to a USB drive and then convert it with a program on a PC.
I believe that you steered me in the right direction about this earlier in this thread when I was trying to get my save from Diablo off my PSP to Pops (similar process, if not identical).
I'll re-link the program if I get a chance, but might be a couple days until I can double check what I used on my PC.
--EDIT--
You linked this on February 5th and it worked for me:
