Modding Can you swap circuit boss with boss from another circuit?

[Big_boy7]

Hello! So basically what I was wondering about is, is it possible to swap boss of a circuit to bpss from another circuit? and I don't mean changing models of other racers into other bosses because I know that's possible and have seen it at least few times. What I would like to do is for example make King Kahuka (circuit 2) race on Captain Redbeard's tracks (circuit 1) as in swapping AI paths files, boss car and character model file and eventually swap AI of a boss so that he still collects blue bricks like normal, unless it is directly related to AI paths.

AI paths are like train tracks, they're entirely pre-recorded from developers of the game. So the AI doesn't "try to" pick up certain powerups per se, the developers literally just aimed for specific kinds of powerups while recording the routes for each boss. IIRC there's files that determine *when* the AI racers prefer to *use* the powerups, but that's about it.

I guess all you need to do is just swap models of bosses then to do what I was thinking of?

The file MENUDATA\LEGORACE.CRB determines what racers race in each circuit
You can edit that file with the binary editor to make the changes you want.
 

k_27    // Circuit
	"c1"
	{
		k_29    // Circuit Number
		1
		k_28    // Players
		[6]
		{
			"KK"
			"KK"
			"IL"
			"RK"
			"CC"
			"TC"
		}
		k_2A    // Circuit Number (duplicate)
		1
		k_2B    // Circuit to unlock after this
		"c2"
	}

Each circuit has an entry like this.
In the k_28 list, the first entry is the racer you will see in the demo, the second entry is the rival boss, and then 4 more entries for the other opponents.
