Remove credit card types in v 1.4.9.4

I have searched all through the forum and keep hitting a blank wall.
Trying to remove the credit card types "Maestro" and "Solo" from the drop down box upon checkout.
I did manage to find and remove the "start date for Maestro cards"
I am using paypal pro for checkout.
v 1.4.9.4
thanks for your help

Found it. Here for PayPal Pro users who do not want the Maestro and Solo in the drop down.

catalog/controller/payment/pp_pro.php

I just deleted a these few lines:

$this->data['cards'][] = array(
'text' => 'Maestro',
'value' => 'SWITCH'
);

$this->data['cards'][] = array(
'text' => 'Solo',
'value' => 'SOLO'
);

I hope this helps someone on 1.4.9.4
