ROM Hack Yu-Gi-Oh! DS game disassembly

g00dman · Feb 22, 2017

Hi, I could only find one other thread on here about this and it didn't answer all of my questions.

My main question is, how can I open the .pac files for any of the Yu-Gi-Oh! DS games (currently dealing with World Championship 2008)? I'm doing a little research and compiling some information about the games. I'm interested in finding the deck listings for the CPU opponents, among other things.

Does anyone know anything about this?

I never extracted/hacked a DS game, but im sure that will help

From my understanding .pac files holds graphics (tiles, pallets, etc) and is not really what you're looking for imo

All the files I have here add up to 128 MB, which is the same size as the full ROM

Well, through a lot of messing around with hex editors and figuring out what corresponds to what, I've managed to do what I set out to do.

I can detail the process a bit more thoroughly if anyone wants to know.

Nice. Have you determined hex locations for each of the cards? Could help for anyone who wants to make codes for this and possibly subsequent YGO DS games. Some guy created a hex edit program for Spirit Caller and WC 2007.

Didn't get quite so far with it, no. All I did was find the deck files and determine which value corresponded with which card.

Every card has a specific ID number, for example AA0F - 0F is the 'bank', if you will, and AA is the card's 'number'. So, as a random example, Call of the Haunted, an earlier card, has an ID number (I believe) of 7C13 (card 7C in 'bank' number 13), and a later card like Chimeratech Fortress Dragon is in 'bank' number 19.

I hope that made sense.

Interestingly, there are some ID numbers missing, since there are also cards missing from the game. As another example, the chess-themed 'Archfiend' cards aren't in the game, but the ID numbers they would have occupied are skipped out (again, if that makes sense, lol).

I'd be totally interested in any particular ROM editing endeavours for this game or any others that play on the same engine (Nightmare Troubadour, Spirit Caller, WC 2007, etc).

That's logical enough.

It could help with creating any AR codes (i. e. 9 copies of card X).

Know of any way to make an Action Replay code to put the player under control of the AI? (like in the Darkness world when playing against the Aliens)
