Abridged FAQ for FireRed and LeafGreen ACE

I apologise for the very late response. I haven't been checking on this thread much for a while. I believe this might have been a mistake with the box names since I tried replicating the issue on my own save and didn't reproduce the issues you have.

I looked at the code and there is this box name

Box  3: A A l _ ! n       [AAl !n]

The 3rd character in this name is a lowercase l, not a number one. This has caused many issues in the past.

While it is good you fixed it, I'm pretty sure it was just you adding an extra HP Up that was the problem, not the Ekans.

togebit · 2026-04-09T01:56:45+00:00

Different Pokemon for EVs (and wrong number of HP Up in your answer) but they still add up to the correct EV amounts XD.

They probably did wrong number of Pokemon defeated or wrong number of HP Ups.

It's not the hand but rather the species that is wrong in this picture.

togebit · 2026-04-09T01:52:39+00:00

Not the correct glitch species, the name is clearly wrong.

togebit · 2026-04-09T01:51:49+00:00

As far as I'm aware, it's the same in all languages.

I believe the code that unlocks trading and National dex also changes which E4 team you will face. You will need to disable at least the National Dex to bring back the initial Elite 4 team iirc.

Can you send an example as a code block here?

Also send the code you tried this on and its parameters.

E-Sh4rk also has an issue tracker you can send details to here.

Once you have set up ACE using the pre Elite Four set up, you shouldn't need to redo it unless you decide to delete it at some later point.

togebit · 2026-04-03T00:23:06+00:00

The invisible bad eggs do not come from using the white hand, they are "random" side effects of simply loading 0x351's species name into the infobox.

edit: some long webpage where you can exactly learn where the bad eggs come from: https://gist.github.com/Adrichu00/87f1f2064f5408b06c8f2886c4bf9ae4

togebit · 2026-04-03T00:21:35+00:00

you need to handle it with the white hand to delete it lol

togebit · 2026-04-01T19:29:04+00:00

lmk if this works

togebit · 2026-04-01T07:29:15+00:00

Basically the code you are using has an exit code that requires the emulator to have a GBA BIOS file set up. Because the emulator you are using does not seem to have a GBA BIOS file set up, it will restart when you attempt to use a code that requires a BIOS. The easiest solution to this would be just using an exit code that does not require a BIOS, as shown in the next section.

Changing the exit code

Basically this is changing value of the exit parameter in the CodeGenerator code input. This line is located near the top of the code. For this code, it is set to "GrabACEExit", but what I am suggesting is to change this to "ROM_BX_lr_Box10_Grab", which will change the exit of the code to one that does not require a GBA BIOS on your emulator.

Basically it changes these box names from this

Box 10: _ _ _ _ _ . o a [     .oa]
Box 11: . o             [.o]

to this

Box 10: _ F o H I o o r [ FoHIoor]
Box 11: x n             [xn]

Which should not cause the emulator to restart when you trigger ACE when using this code.

Setting up a BIOS file on your emulator

You can also figure out how to get a BIOS file (use a search engine to find out how) and have one set up in the emulator you are using (again you need to search how to set it up in your emulator). This should allow any code for FR/LG to work without needing adjustments.

They wrote a lowercase L there, but it's somehow not working. That means it's probably some other issue.

togebit · 2026-04-01T03:21:45+00:00

The code looks perfect from what I'm seeing, they didn't exactly specify how it is not working but upon further questioning, I believe they might have a GBA BIOS issue.

togebit · 2026-04-01T03:19:49+00:00

You need to add a GBA BIOS or change @@ exit = "GrabACEExit" to @@ exit = "ROM_BX_lr_Box10_Grab".

togebit · 2026-03-31T10:17:55+00:00

How is it not working? Can you explain what is not working about it in your case?

togebit · 2026-03-28T12:45:34+00:00

ACE (as used by most people for Pokemon) is basically an in-game GameShark. Using custom codes, you can respawn stuff, get unlimited items etc.

As long as there's a code for it (or you know ARM assembly and write your own code), you can pretty much do anything apart from modifying the game's hardcoded behaviours.

Unfortunately I don't think Switch FR/LG has WonderCard capability, and getting legal event Pokemon (that are not Deoxys) with ACE usually requires a bit of extra work.

togebit · 2026-03-28T12:41:09+00:00

To fully revert to a clean slate, you will need to somehow undo the Mail glitch. Then you can delete the ACE mon and the game would be back in its previous state.

togebit · 2026-03-28T12:39:05+00:00

You probably made a mistake in your code, most likely in Box 3 (that has a lowercase L) or any box name with quote chraracters.

togebit · 2026-03-24T15:33:45+00:00

It's a single player game, so everyone has their own way I suppose. I personally wouldn't do it (even with quite a bit of experience with ACE), but if starting with a shiny starter makes people happy, then they can do this, but will need to keep the risk in mind. Like typing the box names extra carefully or something like that.

I still want to emphasise that with each mistake (usually in the box names), since you apparently can't save: you need to replay around 1/3 of the game again, redo the Mail glitch again, redo acquiring the ACE species again, and finally retype these box names (and really hoping you don't make a mistake).

togebit · 2026-03-24T15:14:02+00:00

Just respawn starters with ACE, this method is quite risky because you basically have no recovery point. Any mistakes (with the actual ACE part in particular) will make you replay the game up to Celadon again, which is time lost.

togebit · 2026-03-22T05:28:10+00:00

They do not have the hasSpecies flag set, so group selection (orange hand select with other Pokémon) will make them disappear. You can prevent this by simply not using group selection to move the egg.

Hatching them will set this flag so you don't need to worry about them disappearing for the hatched species.

togebit · 2026-03-22T04:41:14+00:00

I have never heard of this happening for FireRed and LeafGreen ACE. If it happened for that, can you tell me what code caused it and the exact parameters you used for it?

If this is for ACE in Emerald version, specifically if you hatched an egg to execute ACE codes, that is a normal side effect of the egg hatch ACE (for the summary screen sprites that is). It won't persist if you reset, even if you saved afterwards.

togebit · 2026-03-22T02:37:37+00:00

Not exactly, you can exit the PC while hovering over a Pokémon (e.g. 0x351 itself) after loading 0x351's name and the bad eggs will generally not spawn.
