Other than using Satconv (DOS
) to change the region code to suit your Saturn, there's not much more you need to do.
There are some games that have been optimized to run at full speed and/or full screen on a 50Hz PAL TV, but not that many.
When using Satconv look at the product code. If it's MK-8xxxx-50
chances are good that it's PAL optimized. While all Euro games had that type of product code on the box, I believe only PAL optimized versions have them in the CD's header.
Some have different version numbers instead and are harder to pick.
