Screen exits have 7 bytes in the GBA version. They follow the same format as the ones from SMW2.
In SMW2 level 6 has those screen exits:
7F 06 00 2A 02
11 3F 0E 1E 09
74
E2 4B 73 06
76 36 C7 00 08
7F 06 00 2A
06 96 04
11 3F 0E 1E 09
9A 04
74
FA 4B 73 06
27 00
76 36 C7 00 08
99 05
As you can see, the E2 turned to FA in the GBA version. Do you know what that means?
That FA is a Bandit-Minigame. So levels F6-FF are probably the Minigames.
I've tested 'em out for you:
F6 Throwing Balloons-1-Up
F7 Throwing Balloons-2-Up
F8 Throwing Balloons-3-Up
F9 ???------------------???
FA Gather Coins-------Egg-Filler (Maybe other things, too)
FB Popping Balloons--10 Stars, 20 Stars?
FC Popping Balloons--20 Stars, 10 Stars?
FD ???------------------???
FE ???------------------???
FF Seed-Spitting------Watermelon-Item (Means Water, Fire and Ice)
All the ???s are the same: A blank Bandit-House with no Bandit and no Yoshi and no decoartion with a message box popping up and close, then the game freezes. As F9; FD and FE seem to be empty they could be "transformed" into levels by changing the pointers to these levels.
The two Unknown Bytes are very confusing. If you change them you get some "earthquake" effects when entering. They seem to change from Entrance Type to Entrance Type. However, some of them seem to work everytime.
