Regarding Donald Duck - "Works on POPSLOADER for 3.80M33 v2 + set game ID=SLPS02180. When popsloader loading menu appears, select 3.00, 3.01, 3.02, 3.03 or 3.10 pops ONLY, game does NOT work on pops versions above (hangs up after 2 intro movies)!!! Tested by MAN-biker on PSP Slim FW v3.80 M33-5"
For Spyro, if you're using the US version make sure you are using the following ID: SCUS-94467
