Set up:

The French started with an advance by the archer cavalry up their left, which came to grief on the Burgundian right wing gendarmes. The French gendarmes crossed in front of the Swiss pikes to succor the French archers and began a large swirling fight with the Burgundian gendarmes. This sucked in one of the French generals, and the Burgundian CinC. The French mtd archers were destroyed, and in turn, one of the Burgundian gendarme units was destroyed, and in turn one of the French gendarme units was broken, and another was first disrupted by the Italian mtd xbow, and fragmented when their friends were broken.
The Swiss advanced, and spying the Burgundian archers in the enclosed field, charged them right through the enclosure, eventually routing one of the burgundian longbow units, but in turn were charged in the flank by the other burgundian longbow unit and were routed, The French King (CinC) being captured by Antoine, bastard of burgundy (TC)
The Burgundian center advanced, but the center Burgundian longbow unit lost a protracted fire fight with the Francs archers, French handgunners and French xbow, being broken by missile fire alone. The voulgiers and Burgundian pike went head to head, the Burgundian pike eventually routing the voulgiers, despite the intervention of another French general, who was skewered off his horse. The Burgundian pike then charged and routed the Francs archers. (who had been fragmented during the firefight with the Burgundian longbows)
The left flank Burgundian gendarme unit led by the Count of Romont (TC) charged the right hand French gendarme unit (which turned out to be Italian mercenary knights) and were destroyed in a single turn of impact an melee.
This sent the French Army routed at this point from a compination of broken and fragmented units.
There was a lot of see-saw action, and I am reminded of Commynes comment about the battle of Montlhery: "Never was there a greater flight on both sides."
The guns were pretty much useless. The fortifications, however, may bear some more experimentation.
