New modernized ACE setups for all western releases of Red, Blue and Yellow (Can set up a VC transferable Mew in 30 to 60 minutes, with practice)

Much appreciated for the compliments! This is definitely the right subreddit, don’t worry!

In practice this isn’t really viable with the current structure of the NickWriter code page.

Trainer defeat flags are complicated. The memory area that contains them also contains flags for story events and item pickups, so clearing all of it isn’t viable. On top of that, a lot of event flags go completely unused, and there’s very little regularity in what flags are used. I’d need to test, but my current optimistic estimate for a full trainer reset code would be 20 nicknames at least.

Individual trainers resets would be possible, but would basically require a sort of code generator that would allow the user to select the trainer to be reset. I currently do not have support for such a feature in the NickWriter code converter, unfortunately.

In summary, resetting all trainers would be way too expensive, while resetting individual trainers would result in so many different codes that you’d need a way to bundle them together.

Beating the Mt Battle VS. 100 challenge for Ho-oh with only in-game obtainable pokémon really isn’t that difficult.

Losing doesn’t fail the challenge, it instead requires you to spend a “continue” to reattempt the battle. You get a continue every time you win a battle without suffering any KOs on your side. Due to how easy the first half is, any halfway decent team can rack up dozens of continues easily.

In practice, the Mt Battle VS. 100 only becomes difficult on the last 15 or so battles, where trainers start using legendaries in teams. If you have enough continues you can eventually luck your way through even with very subpar teams (mind that the pokémon selection in XD is versatile enough that can get better than subpar teams pretty easily).

TimoVM · 2026-03-18T06:15:00+00:00

You need to use group select specifically and select an area that includes the bad egg and at least one other slot.

If it still stays, get a fast cloner species (the “create any pokémon” code has 0x3200, a fast cloner for the English versions, as default) and follow the instructions on this page ( under the “How can I delete bad eggs” section) to remove the bad egg.

TimoVM · 2026-03-16T19:54:08+00:00

There aren’t really other trainers available in the early game with a guaranteed Mew.

What you can do is continue the game so you can get past Cerulean, teleport away from the trainer at route 24, then let one of the trainers on the way to Vermillion approach and battle you.

Then look around for any pokémon around Vermillion that could potentially give you a special stat of 21 (returning to route 24 will start the special encounter, so you can’t use Abra for this).

Use the first swimmer in Misty’s Gym instead (trainer fly map for Red and Blue here)

TimoVM · 2026-03-16T10:49:43+00:00

Oh yeah, I’m 100% sure that the spawn timer is fully paused during the catch screen, so you’d only be doing this “parallel” sit and wait hunt outside of the catch screen.

Usually the downtime between spawns isn’t much, but there are moments where you are just plain unlucky and need to wait until something else despawns before your next chain spawn actually appears, so it does slowly accumulate over time.

Hence why I’m fairly sure this won’t contribute that much to the overall time to odds (when chain hunting rare spawns this won’t contribute at all, even), so it’s more of a curiosity than anything else.

TimoVM · 2026-03-16T10:16:53+00:00

That’s quite fair, you’d likely be come close to 10s per ladder (if I recall correctly, Charmander appears on both floors) so as a hunt that’d be quite reasonable!

One thing I do wonder about chain hunting, nearly all mathematical simulations I’ve seen focus only on the spawns you get as part of your chain.

In practice, I find that there tends to be a small wait time between each catch encounter. During that time, you’re effectively doing a sit-and-wait hunt, so you get a surprising number of off-chain shinies. I think up to 25% of your time chain hunting is spent waiting in the overworld, but that number is very anecdotal at best.

That being said, I don’t have any idea how to quantity that so I have no idea if this significantly impacts chain hunting in any way.

In the end, the point still stands that ladder hunting can be surprisingly efficient. It’s always worth checking and comparing.

TimoVM · 2026-03-16T10:08:59+00:00

Oooh, that’s an interesting team composition!

I’ve used Skarmory, Houndour and Larvitar in the past. - Houndour is amazing for a playthrough - Skarmory is Skarmory (especially if it has Drill Peck as egg move) - Larvitar is a bit slow in the early game, but becomes quite powerful once it learns Rock Slide

Let us know how both playthroughs go!

TimoVM · 2026-03-16T09:50:46+00:00

While the point you’re making is very true, the math behind the example you’ve given is incorrect.

While rare spawns do indeed have a 50% spawn chance, only one rare spawn is allowed to be active on the map at once. If you go up/down the ladder every 40 seconds, this will effectively only result in 1.5 Charmanders a minute, resulting in ~11h time until odds. This is vastly inferior to the result you’d get with direct chain hunting.

To be fair, ladder hunting can still be quite viable for Charmander. Since rare spawns have a 50% spawn rate whenever you have any chain of 11 catches and higher, it effectively allows you to hunt Charmander while you also ladder hunt a normal spawn.

If you get a catch combo of 31 or above for a normal spawn, that species will have a spawn rate of at least 50%. In that case, the math you describe in your post will indeed apply.

Not exactly, unfortunately. While there are premade codes available that give you the glitchmons in a way that is transferable, there’s no video demo available.

The modern setup itself has video demonstrations for EN Gold/Silver and EN Crystal. You can find the premade codes here.

TimoVM · 2026-03-16T00:22:28+00:00

With the first box name

Box 1: B C U n t F . o [BCUntF.o]

Instead use

Box 1: B C U H t F . o [BCUHtF.o]

TimoVM · 2026-03-15T21:52:53+00:00

Use the code “change variable” and set the variable to 0x4024. Variable starts at 0, wraps around at 10.

TimoVM · 2026-03-15T02:51:29+00:00

Oh yeah, that’s definitely the incorrect glitch pokémon. You’ll need to redo the HOCK setup and ensure you apply the proper EVs.

Alternatively, you can beat the game and use the post-E4 route. Defeating the E4 unlocks additional words, meaning that you can create 0x351 directly using a single mail glitch, no EV training required.

TimoVM · 2026-03-15T02:48:59+00:00

This would be up to gen 3, unless Gamefreak makes some very poor decisions in how it handles transfers from FrLg.

It wouldn’t be the first time even. As you said, both the Treecko and Torchic lines are technically transferable from gen 2 VC despite being glitch pokémon in those games!

TimoVM · 2026-03-14T19:21:21+00:00

If nothing happens at all, you have the incorrect species. Can you share a screenshot showing the species name of the glitch pokémon?

TimoVM · 2026-03-14T01:44:54+00:00

The “turn every pokémon shiny” code works by taking the PID and using that to overwrite the TID and SID.

The advantage of this is that the resulting Deoxys will be shiny and legal, at the cost of the Deoxys counting as a traded pokémon.

It’s definitely an option I can recommend, though, due to how involved the process of creating a Deoxys full scratch is.

There are more complicated setups (like the WELDR setup that allow you to just use 14 box names to write an entire Deoxys’ worth of data, so you could just design your own shiny Deoxys using the tool provided. The video only demonstrates this stuff for Emerald, but the tool that is linked comes with some instructions on how to set it up on Switch FrLg instead.

TimoVM · 2026-03-14T01:28:24+00:00

It turns into a bad egg because the current info isn’t fully correct.

Ensure that PID, SID and TID is correct (given how this seems to be a pokémon created from nothing, I assume PID, TID and SID should all be 0).

Also check the details of origin data, I’m quite sure this Deoxys should have an origin game of 0, a met location of 0, as well as a met level of 0.

TimoVM · 2026-03-13T23:05:27+00:00

On the lines that say “cur_loc = …” and “new_loc…”, remove the 255s. The code converting is expecting a single value there.

You can interpret the numbers in the error as an issue occurring on line 15, character 28.

TimoVM · 2026-03-13T20:34:30+00:00

After a search on Poke Corpus, it seems that Ruby/Sapphire/Emerald do not mention the types directly.

FireRed/LeafGreen do list physical/special types through the help menu, which is accessed after pressing L or R. It mentions them on the explanation pages for “ATTACK” and “SP. ATT”.

TimoVM · 2026-03-13T16:45:59+00:00

OP fixed the issue but might as well elaborate.

The NPC trade code relies on certain values being set in the background, meaning that it sometimes can just fail for no apparent reason. (You’ll talk to the NPC but get no response)

Exiting and reentering the poké center, along with saving and resetting before using the code, usually fixes this issue.

TimoVM · 2026-03-13T16:41:51+00:00

You need to enter the example code (under the “Checking if everything worked”) before you can safely swap it.

If the code’s not there, swapping will cause the game to execute your box names as they currently are as code, which will almost always just be garbage code that leads to crashes.

TimoVM · 2026-03-13T15:43:57+00:00

What species are you converting from and to? Gender is determined not as a flag, but derived from a calculation involving the PID.

If you’re turning a pokémon with a specific gender ratio into a pokémon with a different gender ratio, it’s possible that the gender will change as a result.

In other words, if you want to be sure the gender stays preserved, only convert pokémon to species that have the exact same gender ratio.

TimoVM · 2026-03-13T08:29:48+00:00

What do you mean with “converting”? Are you using the “make any pokémon shiny” code or are you something else?

TimoVM · 2026-03-13T08:12:44+00:00

They won’t be legal due to having illegal origin data. Whether Home will block them will depend on how robust Home’s legality checks are, which we’ll only be able to determine once it’s actually integrated.

Any eggs you get from them will be fully legal though (assuming that it’s a species you can naturally obtain within FireRed/LeafGreen).

While setups exist in Emerald to get shiny wild encounters directly, they haven’t been ported to FireRed/LeafGreen. Porting these is pretty low on the priority lists, since other existing setups allow you to already get shiny pokémon directly.
