How to change the frame rate in saved games?

Hi people, I'd appreciate if anybody could help me with this... My computer broke down recently and I had to transfer the entire GP32K to the new one. But there the game doesn't run so smooth so I had to decrease the frame rate somewhat (to 21 FPS) in order to bring the PO down.

However, the games that were saved on the previous PC have the old frame rate value embedded in them (25 FPS), which is too high for the new PC.

The question is: does anybody know how to hack a saved game and change the FPS manually, using a hexeditor perhaps...? Thanks!

Bump

Anyone?...
