What about the Lp set? I saw you'd come back to it but I don't think I saw where you did. I might have missed it. Thank you for all the information!

The game guide actually goes into detail on the genotypes for the various appy patterns in the Horse Genetics section.

Hey a question if you breed a blue roan with a chestnut, what would you get? My guess would be Bay roan? Or is there a possibility of a solid? Or what would be the results?

It would depend on the horses' specific genes, especially for extension and agouti. Blue roan is black + roan. A horse with a black base color can have Ee or EE extension but will always have aa agouti. A chestnut horse will always have ee extension but could have any agouti (AA, AAt, Aa, AtAt, Ata, or aa). If they have the agouti for bay (A) or for brown (At), the offspring may be bay or brown based, otherwise they will be black based or possibly red based if the blue roan horse has Ee extension. If the blue roan horse is only Rnrn there will be a 50% chance of it passing to their offspring. If it is RnRn, then all their offspring will be roan.
