@Kaphotics I'm hoping this can be added to PKHeX.
I pretty much worked out all the needed data,
except I'm a bit lost regarding the Checksum 2

This should be correct, but confirmation would be good.

0x1A13 - 0x1C38
0x3DD8 - 0x3F79
0x106B - 0x1533
0x7E39 - 0x7E6A
0x1534 - 0x1A12

Checksum: 0x7E6B

The 5 values on top, I assume they're initially written at the next 2 bytes, then summed again and written to the final location?

Calculate a sum for each of those areas, then sum those sums together to get the checksum and truncate it to be a 16 bit value. The sums of the single areas don't get written anywhere.

I grabbed all the bytes and did a calculation on my Excel,
I confirm that calculation checks out.

Summed up values are 159B0, and the values at my 0x7E6B-6C is 0xB059.

Thanks for confirming the checksum calculation!

Now to complete this:

0x1A58 is indeed the time played, but from the backup save. For the primary save it is at 0x204E.
Player palette is at 0x2065.
I'm not sure about the daylight savings, but it seems to be unused in the Korean games. Mom doesn't ask you about it.

Done!

It'll be cool to edit color palette, even if it's not legal XD

Is the Korean version of GS out now ?

 

The original GBC releases GS version for Korea.

Also, just so ya know, the VC releases of RBYG contained the exact same roms as original releases of the games,
just that they also have a patching function that can patch the VC content when running.

The saves also were saved at the same offsets, hence chances GSC save offsets for VC will be the same as the original release.

Cool, it might be worth starting Silver now then, and import the save file when the VC versions are released :)

Do remember that the saves of Gen I and Gen II games cannot cross language :)

Yeah, I've prepared a bunch of saves for the reason. Playing on Korean once in a while XD

It's pretty much confirmed that VC G/S will not have Korean games (no announcement for korea), thus is there really a need to have it incorporated to PKHeX? There'd be a lot of required things:

  • Different character table (strings)
  • Different item/species/etc names (strings)
  • Prevention of loading to VC1/Gen7 games
  • Mixing in a 3rd set of offsets

Korean G/S would be locked to itself, so I don't see a need to support it in the multi-game editor (pkhex). Maybe a separate program / fork of PKHeX is best? Korean G/S is essentially a rom hack ;)

@Kaphotics There is an announcement for VC GS in korea:
http://www.pokemonkorea.co.kr/VCGS/

 

I would agree that it'll be kinda of a hassle.
At least Korean Encoding for Gen II is already documented.


Also, the Korean save structure is similar to the ENG games, and as a result, they are able to trade without corruption.
(Just traded from Silver KOR to Red ENG yesterday) [of course I do not know if it'll be incorporated into VC]

I no longer have any to test but I seem to remember something similar of the sort. Something about the data being handled differently and you couldn't really trade between then. I might have tried with English and Japanese gen 1 games back in the day.

English with Japanese trades will certainly cause problems.

I did Korean and English trade, and the English Pokemon kept their English names on the Korean save!

The Korean Pokemon names on English saves looks like garbled nonsense, but beyond that it functionally works.
(Tho for this very reason, I'm afraid VC GS KOR won't have time capsule and trades with other languages)

That's sorta how it works in gen 3. When you trade an English Wartortle to a Japanese Fire Red for example, it will be named WARTOR. And if it evolves, it will keep it's name. Same with Japanese mons on an English game and probably any language. I never tested with the others (I could). If you migrate a non-native Pokemon, it's name will be treated as a nickname. So a French Articuno will be named ARTOKODIN when it goes through bank. I migrated the in-game-trade Farfetch'd named CH'DING to gen 4/5/6/7 using a Japanese save for gens 3-4 and it's nickname was preserved, despite being shortened in gen 3. I never tested with a Pokemon like Wartortle in a Japanese save though. 

The point of all this is:

This is in gen 3 where you can trade between all the languages and they didn't really fix it properly until gen 4. Where Korean games can't trade with the others, as I was told. So I highly doubt something as far back as gen 2 could work properly. It would just create an interesting nightmare.

(Also, mind sending me a Korean gen 2 PKM? I'm curious about what happens if I evolve it and if I migrate it using bank/if I even can and what happens if I trade it to gen 1if it's a gen 1 mon, etc. Lots of experiments and tests to run.)

I didn't think of that. I assumed they'll treat it as a glitch Pokemon, due to its nickname.

later, upload to here a Gen 1 vc save (tell me for which game), and I'll time capsule a Korean Pokemon to it. (Also prepare 2 trash Pokemon in your party, for the time capsule procedure)

IIRC when PKHeX modifies such a Pokemon, the nickname and OT gets wiped out, so at this point, attaching a PKX file wouldn't work.

I'll have to find a gen 1 save online. I don't currently have any gen 1 carts. Just a Silver cart. I really can't wait for these gen 2 VC games to be released. It will put to bed so many questions.

When you said migrate, I assumed you had a Gen 1 VC game ><

yeah, but bank support won't be out until nov 17.

at least trading questions would get resolved :)

Korean GS has buggy support for non-Japanese games, including Crystal. A few interface issues where longer names overrun the dialogue box. Sometimes trying to link may freeze up too.

It's kind of unavoidable for completionists. Supposedly Mew and Celebi were never distributed to gen 2 in Korea.

gen 5 at long last introduced normal trading with Korean

So do Japanese and Korean games trade together fine? Cause now I would like to know what happens if you send an English Pokemon to a Korean save. Then trade the English Pokemon to the Japanese save and the Japanese mon to the English save and what happens when it evolves.

Outside of doing the coin case glitch in an English game, you could get the events in an English game and trade them to a Korean save. Then just release the glitched name mon from the English save.

No. Korea and Japanese games were first compatible in Black and White.
