ManualsLib has the manual for the SD-533HD5 here: https://www.manualslib.com/manual/384249/Pioneer-Sd-643hd5.html
. (The manual covers two models.) Once you modify the picture parameters (starting from STD, REF THEATER, GAME), these are stored as the User mode. If you press Menu when done changing the parameters, that input should maintain the User settings for the last setting until you change the Picture type. If you modified the parameters for STD and then return to that input and change the Picture to GAME, any modifications to the GAME picture parameters will become the new User Mode. See page 50 of the manual for the details: https://www.manualslib.com/manual/384249/Pioneer-Sd-643hd5.html?page=50#manual
I hope this helps.
