Works for the EN and FR versions of the game (so I guess it'll work for any other european version).







On a side note, if any hacker is interessed into looking into it, the game seems to have something enabled with a key combo.
Be in the simpsons house, put a bpx at 0x020AF11C for the french game or 0x020AF0EC for the english game, then press the following keys in this order : XXXXLAAALYYLXL.
The emulator will break, however it doesn't seem to do anything at that point. Having pressed this key combo makes r3=0xE, however that value doesn't seem to be used anywhere... (maybe this is a debug menu, and they removed a part of it ?).

Interesting.
If it doesn't crash a real DS, perhaps you should notify Martin about it. Technical bugs always make him happy.

I'd be willing to test this on a real DS, if you could give me these instructions in the form of an AR code.

Also, thanks for the codes.

There is nothing to see on a real DS.
Anyway, if you want to 'witness' something, here is a code for you :
EN :
020AF0EC EAFFFFFE
FR :
020AF11C EAFFFFFE


Now be in the simpsons house, and press the keys I gave (XXXXLAAALYYLXL). The game will freeze (that's because of the code I gave you - else nothing happens), showing that the game 'recognizes' this key combo. However, it seems to do nothing at that point. Like if something was supposed to happen, but it's not happening (anymore). That's why I'm guessing this could have been used to bring up a debug menu (for the betas), and that was removed in the final version. But as they "forgot" to remove the part that recognizes the key combo, maybe they forgot to remove something else, and maybe the debug menu (or whatever that is that was supposed to happen) could be 'resurrected'... I looked a bit into it, but found nothing.

I also could be totally wrong, and this could be some kind of cheat you have to unlock during the game...

Yep, the game freezes and the music continues, with the touch screen completely unresponsive. However, the key combination to return to the R4's system menu (A+B+X+Y+L+R) still works, so it doesn't completely crash the DS.

Edit: Just wondering, how did you find that key combination, and did you find any others?

I'd also love to know how you went about this.. =D

I followed the buttons read routines (from 0x04000130), then I watched the different places where it was copied/readen from (using bprs/bpws), and doing that I found that small routine that was comparing a buffer that holds the last 14 keys that have been pressed with some table.
So I just had to look at the table's values (which was like 0A0A0A0A090000...), convert these values to keys (just looked at the buffer, pressed a key, and I knew what was its value ; 0A = X, 09 = L, 00 = A...), and I had it : XXXXLAAALYYLXL.

Edit : I guess I was lucky macking that seach inside the simpson house, because I wouldn't have bring up anything elsewhere...

And no, I didn't find other (but I didn't look for any other either..).
