can i not play certain games w/no solder mod??

[boysmoney]

hey all,
I have some bu's that don't work. I have a back up for my smugglers run 2 and it makes a high pitched noise the whole time the game is playing? I also have bu for moto gp and it only plays in black and white. Are these prob's due to my mod chip? again its a solderless chip. thanks !!
