I was messing around with the out of bounds areas in OOA, and came a cross this glitch. When I selected that tile (It would be C 15 on the map) it locked the game. I messed around with it a bit more and each time it seemed to just give a graphical error and lock the game. one of the times selecting the tile sent me to the screen that comes up if you put the game into an original game boy (the one that says it can only be played on GBC). I came to believe that what happens after selecting the tile is based around what is drawn on screen, and I eventually found a pattern that allowed me to regain control after selecting the tile, but the game locks shortly after doing anything. One of the times, the game took me back to the file select screen, all of the files were erased, and the game was locked. when I reset the game, all of the files were indeed erased. I was wondering if anyone had any more information about this odd bug, a few google searches revealed nothing. I also found that it does not work on Visual boy advance, but does work on 3DS/GBC. I advise caution if messing with this bug, I have had it wipe my saves (as stated above) and crash my 3DS (it was fine after resetting the console) Edit: forgot the link, thank you Patashu for linking it
06-12 = nothing (sometimes changes music tempo ???)
13 = crash
14-22 = nothing (?)
23-25 = shooting gallery "strike" sound effect (sometimes crash?)
26-2f = crash (invalid opcode)
30-3c = crash (because of 2f)
3d-5e = crash (because of 3c)
5f-77 = crash (because of 5e)
78-79 = graphical map glitch
7a = graphical map glitch + get rupees (???) (second time crashes)
7b-81 = crash (because of 7a)
82-83 = crash (different cause)
84-89 = graphical map glitch (1st time), use A button item (subsequent times)
8a-92 = graphical, audio glitches (1st time), crash (subsequent times)
93-9a = crash (because of 92)
Because I couldn't get the bug working on emulator, I went to test the "This would correspond to whether you've visited that tile" part. I went OOB and checked every tile as I proceed across that row, I was able to get the bug to work after I visited the tile right of the bugged one (D 15). Could you explain the "If there's no time portals or anything on the screen" part of your post? if there are time portals on screen, what happens to that value?
That is an interesting tile, I found another tile that lets you regain control of link, as I stated originally, and after experimenting with it for a few minutes I can conclude that it is not as complex as I thought, it involves making a time portal at (5,4) (the upper left tile of the middle of the 'X' on screen), then digging the tile to the left, hitting select on the second frame of the digging animation (the shovel is on the top-right of link's sprite). then selecting the tile within a small frame window (normally it works after half a second of the arrow showing your current tile appearing). this will give a similar result of being at 7a, but the game will crash upon doing much of anything else. I did this result after regaining control from 7a, and it reset the game, but the game was much brighter than before. Edit: after doing both selections a few more times, It doesn't always return the result of resetting the game with a brightness error I have no Idea what all affects this outcome, I can only get it to work a small part of the time. (I also thought that it might be tile specific, but have gotten it to work on other tiles now) Also, when I select the buggy tile while at 7a, I lose 30 rupees, not gain
Alright so I noticed an odd side effect of selecting the tile while at 7a. the second start screen is glitched (as found before). the screen looks like it has been taken over by rings. you can select things on screen like normal, however if I go to where the ring box should be, It instead says the text for bombs, but I cannot equip them. also, If I select the last ring I have and hit right, which should bring me back to the first item, it instead goes to another ring. I can scroll through a huge list of random rings, most of which are the friendship ring. I can equip any of the rings and gain the effects of the ring. I have seen the pegasus ring, and the power ring LVL 3. I don't know what determines what rings are in the giant list, but will look into it on another file and see Edit: I tried a different file and different rings are in the list also, the poe clock was in the list (after I have the upgraded sword) and I can equip it
If the majority of people wants to see a linked game TAS, it could easily be changed right now since the run needs to be redone from scratch anyway. In a linked game TAS we wouldn't bother with the Gasha Trees and just get the rings we need from the Ring Secret.
