First see if you can get the game working, then we can help you modify it to show your text.

The picture you posted lines up exactly with the schematic. Put those two pictures next to each other on your computer screen and compare them. Have a look at where each connection goes and you will see they are the same.

The only extra thing you need to add is the one extra wire on pin 2 of the microcontroller to the red cathodes on the led matrix (which should be the red dot in the bottom right corner on bitfogavs drawing.)

I just finished a prototype of the great race for a school project but for some reason column 5 and 7 switched places so all the data that is supposed to be on column 7 is on column 5 and vice versa. This project is due soon can you please point out all possible causes for this to happen?

Thanks

What if you swap the connections over from column 5 to 7?
If you don't know what Voltage your country is using, you shouldn't be doing electronics ;-)

Unfortunately it's very hard for us to know the fault without seeing the physical circuit. But it happens to the best of us whereby we get connections around the wrong way. Give that a try in the first instance and if it's still no good we shall see where we can get to from there.

Thanks again
