Emulation & ROM Hacking / Re: Emulating the Mobile Adapter GB
« Last post by Wack0 on August 16, 2017, 04:26:07 pm »
I wonder how awkward that MD5 implementation is...

Game Freak's parser bugs don't surprise me. An RCE vector here would allow for some interesting custom servers; however RCE via trades exists too, which would be the more dangerous, in my opinion, as any player could trigger it. I guess a custom server would have to somehow detect it (given this RCE vuln would be in the P2P communication with "phone numbers" etc).

And now I'm thinking about a server with its own partial GB emulator, MITMing the connection if it detects an RCE via trading, and specifically implementing GB Mobile Adapter emulation itself so the payload can get any further data... Saved off for further reversing/analysis of course.

(It assumes that the Pokémon available using the Egg Ticket were the same ones, with the same probabilities, as in the English version’s Odd Egg event; I don’t know for sure that this assumption is correct.)
From (ECCH) Bulbapedia:
Quote
In the Japanese version of Pokémon Crystal, there is a 50% chance the hatched Pokémon will be Shiny (IVs 2/10/10/10) and a 50% chance it will not (IVs 0/0/0/0).
In the international versions of Pokémon Crystal, there is a 14% chance the hatched Pokémon will be Shiny (IVs 2/10/10/10) and an 86% chance it will not (IVs 0/0/0/0), but the chance of any particular Pokémon species hatching from the Egg and the chance of any given species being Shiny are not uniform.

Bulbapedia originally said that the Odd Egg had a 50% chance of being shiny in all versions, then that it was 50% for the Japanese event but 12.5% in the English version, then reverted back to 50% for all versions until someone finally came up with the correct 14% figure from the localizations. I have no reason to believe that the 50% figure is anything more than someone’s guess that’s been propagated as fact.
f**k it. At least we can say we tried.

Emulation & ROM Hacking / Re: Emulating the Mobile Adapter GB

Cool! I've backed up all your documentation on http://42chan.org/mgb/gb.html. I always have a server if you need it for emulating the GB adapter..

Great, thanks!

but if they do a Celebi event just like mew there won't be a way to change its id and ot so it transfers on non english versions

Fortunately like Krys3000 said wrong pocket TM code execution (or likely glitch Pokédex category ACE) works fine on non-English versions (however I haven't tested every version). Setting it up however requires the duplicate key items glitch, ????? status corruption, or another arbitrary code method.

Move 00/type D0 code execution works on English Gold/Silver but I don't know the details on whether it works (or if a similar move ACE works) on non-English versions.

Bad clone ACE (also known as unterminated name Pokémon ACE) only works for Crystal sadly, like forsyz said and I've only tested it on English Crystal.

yooooo whaaaaat haaaaappeeeeeneeeeed?

Editing the save file won’t help because the Egg Ticket event is not in the game. There is nothing in the Japanese ROM that defines which Pokémon you can receive from it or what their chance of being shiny is. The only way to redeem the Egg Ticket is to connect to an emulated Mobile System GB with an emulated Mobile Adapter GB in order to download a file which contains the Pokémon’s data. The proof-of-concept Python script I wrote last year links to BGB and emulates enough of the Mobile Adapter GB and Mobile System GB to allow the Egg Ticket to be redeemed. (It assumes that the Pokémon available using the Egg Ticket were the same ones, with the same probabilities, as in the English version’s Odd Egg event; I don’t know for sure that this assumption is correct.)

I do not want to be rude, I want to tell you that I really do not know how to modify the save files or understand the indications they give me since I do not know the subject, I would like to learn, besides not understanding English perfectly since my native language is The Spanish, then I go slowly learning to defend myself better in this language; But for the moment I have no way to divide my time, so I know that what I will ask next is very brazen of me, so I ask if there is any possibility that someone who knows how to modify my game to get the Egg Ticket can To make the necessary modification to obtain it, even if I do not have to pay such a favor, I can wait, if they can not, at least I appreciate the help they gave me, as I gradually lose more of the courage and hope that I can get that rare pokemon that So anxious. Thank you for taking the time to help me and I admire your great work in everything done on this page, especially the Egg Ticket (With the Mobile Adapter GB System).
