pokemon yellow new glitch

[fatman]

Okay so messing around on pokemon yellow I was messing with the safari zone glitch and thought about combining it with the mew glitch. I had never heard of it being done and tried it. Countless hours of messing with my idea later I found that if you made the last step of the safari zone timer on the same step the menu would pop up for a mew glitch (such as directly west of lavender town) that you would be dismissed from the safari zone in a house lavender town. The fun doesn't stop there, if you go back to the route, you will fight a lass with 3 meowths twice (she actually is present on the route I just entered) and she came from nowhere. Afterwards, the route is screwed up, random sound effects are playing and you can only walk in between the loops of random sound effects. Go too far and the game will just freeze such as in this picture
This glitch has no useful effect but is very interesting an explanation of its cause would be very helpful! Please note that if you save this route will still be messed up so save at your own risk! Also note that you cannot have fought the gambler for the mew glitch or this trainer

here is a youtube video of me showing how to do this
video of the effect

Very good job finding this.

I know I've fought that Lass before, obviously not via the Mew glitch or any variation, but I definitely remember fighting a Lass with 3 meowths and that dialogue. If memory serves me correctly, I think she's one of the trainers facing left in the line on that map.

Cool glitch! I especially like how the palette changed for the Safari Zone entrance.

That's a great way of thinking outside of the box. Nice find!

I'll look into this for you. I have a suspicion that the glitch actually changed Route 8's map data. When you performed this glitch did all of the NPCs on Route 8 give the wrong text/garbage text?

The reason I ask is that you can get similar after-effects by directly changing the map number (address D35D in Yellow) so that it doesn't match the actual map. When proceeding to a new route, for example when changing the map number to non-existent map 0x0B when walking to Route 1 you will get interrupted every step like the after effects in your video.

Oh wow. This reminds me of the infinite battling that happens when 0 ERROR activates. In fact, it's strikingly similar. Very creative idea too

Yep, she's on that route. Now I'm curious as to what would happen if you defeated the Lass first.

The only garbage/glitch text is immediately after the first battle when you see a message box right when you get back to the overworld. The message box doesn't even clear before you are treated to the next battle with the same person. After that battle the trainer's losing quote is replaced with two cries and the wild battle music replacing the victory theme. Other than that, all text is normal.

I never would have guessed the glitch would change the map data the game is loading, in fact I would have no clue of even where to begin to explain this glitch so your help is greatly appreciated! Hope this helps!

The lass's quote if you already fought her pops up (I think pidgey and rattata are cute too!). when you cross to the route you will instead battle the wild pokemon corresponding to whatever special stat the pokemon you used for the mew glitch had (in this video's case pidgey) and the glitch will not work. Great question!

Interesting. Now I wonder why it is that Lass. Is she the first in the game's data on the route, or is the Trainer determined by some manipulable factor?

I don't know why it's the lass. I've tried minor tweaks to this glitch (escaping a different trainer, fighting a different trainer on a different route, etc.) but nothing has resulted in fighting a different trainer. I can't even get this glitch to work anywhere else! I'm guessing the trainer that starts the glitch cannot be manipulated and is always the lass for some reason.

This glitch can also happen if you just interact with certain people/signs/objects before walking back to the route. The trainer battle that can occur this way usually causes the effects that you had.

The P.A. system going off and the text telling you to go back triggers the Lass battle. If you had talked to the guy to the right of the Lavender Volunteer House before entering Route 8, you would have encountered the Gambler on that route that's used for the Escape Glitch.

If you had lost to him the first time and returned to a Pokemon Center/MOM's house/Pokemon League, you would have encountered a second Gambler as soon as you appear, (same Gambler from Route 8) but your start menu would still not work. Going back to the route causes the same effects to occur. Messing with scripts and people before entering a route causes things other than the start menu to appear. This glitch causes a script to trigger and close before the encounter starts (or in the case of triggering a trainer, doesn't.)

This is the same reason why you can get the Master Ball early from Sliph Co. It just happened to trigger the event. I've experimented with this glitch and its effects before using Pokemon Yellow in Viridian Forest. I once made an invalid script occur causing a mass of glitch text and sounds to appear (even some glitch text going half way up the screen.) It took a while, but it finally ended with a girl's text from Pokemon Tower properly terminating the script.

What's also interesting is that if you reset or shut off the game before entering the route if you saved after fighting a trainer/Pokemon is that nothing will happen after the script was done triggering. (Start menu, etc.)

The reason why a new glitch did not occur when you took the last step from the Safari Zone into Route 8 is because the Safari Zone recall script triggered before the Escape Glitch's so to the glitch, you, haven't arrived at that route yet. Don't get discouraged though, you may still find something out there, although you're going to need to get creative as R/B/Y is getting pretty dried up in terms of new glitches now.

The reason for the trainers appearing I cannot say. Possibly it calls the last script identifier to have been done on any map and activates it when you enter the area. Hex 00 must call for the Start Menu as this is normally seen if nothing has been done. If a script identifier reaches past a route's indicated script index (as with my Viridian Glitch wall which corrupted half of the route's map makeup) it will trigger either an invalid script or one of the route's scripts.

There was discussion about encountering a trainer twice after doing the escape glitch and messing up the route somewhere on this board but I'm not sure where it was at now.

As for Torchickens, I doubt that the glitch messes with map data (right away) as NPCs are part of the map's scripting and they were all intact, minus when they pop in and out of existence. Not only that, but the BG/tileset is still unchanged. The game does something after each step that causes progressed glitchiness, but I'm not sure what. Sooner or later though, the map may change as seen in fatman's screenshots, but only after a bit of walking happens.

This info still doesn't explain Paco81's Hooked Dragonite glitch because his doesn't involve returning to the route.

I may look into this later.

Wow that explains like 90% of the glitch. Thank you so much for the explanation. It stinks that I'm not the first person to see these glitchy effects but thats life. I'll keep looking for any new glitches I can find in these games
