I've been out of gbatemp for a while, but from my understanding to connect online you need to personally dump identical copies of a game you want to get some sort of code? Did I misunderstand that or has it changed?

I searched this up on gbatemp but had a hard time understanding how it works? Can someone explain it to me in layman's terms? I really want to be able to play my roms online without having the chance of having a friend's copy banned.

Each individual game cart, regardless of what the actual game is, has a header.
This header, for lack of a better understanding, allows you to go online.
Scene (pirated) releases do not have this
Your own dumped games do.
It's possible, (using previously mentioned thread in previous post), to replace a scene release's non-existent header with one ripped from your own/someone else's game
This hasn't banned anyone as of yet
Doesnt mean it wont
But as for right now
its safe

This tool lets you import and export headers. It will also fix any compatibility issues so you don't have to mess with any editing. Have used my personal header for 3 different roms using it. http://www.ds-scene.net/?s=viewtopic&nid=13353
Gateway ROM Patcher v1.0 (by PsyKo)
from http://scene.releases.free.fr/index.php?page=tools
http://scene.releases.free.fr/tools/download.php?dl=GRP_v1.0
------------
+ Changelog
------------

v1.0
- Top part of the GUI is now readonly. Manual edit of cart/chip IDs is now in a dedicated section.
- Some public cartridge IDs can be called in app. But again, use them at your own risks.
- Chip ID generator is back. As usual manufacturer can't be guessed so Macronix code will be set by default.
- Automatic ROM backup checkbox has been removed, you're directly working on the original file now.
- Time has been added in logs and more steps are now detailed.

v0.7
- The chip ID autofix is now splitted in two operations: media type fix and chip size fix.
- game serial size fixed
- many wordings changed

Alright, I tried using v1.0 with a scene release of mario kart 7. I click the public header button, I used the auto detect and I changed the file to 3DZ (and also downloaded the 1.1 Mario Kart 7 patch from the e-shop.) and it keeps giving me the error that I can not go online with this game cartridge. What could be the problem?

if the header was inserted and you renamed it to .3dz the only other thing is that the chip manufacturer is wrong, thats the only bit of the header that cant be figured out automatically.......just try changing the manufacturer in gateway rom patcher until it works (there's only like 3 different options)

Any chance I could get your skype and ask you a couple questions? So I don't clutter forums with troubleshooting posts. I tried switching the 3 different options and still keep getting the same results.

just make sure you followed the tutorial exactly, maybe try a different header and auto patch it....there is very little room for error with

I've tried everything, had an entire discussion with gamequest via PM and I still can't figure it out. Are there certain requirements for the headers ? Anything note worthy, any requirements that could easily make it unable for you to play roms online?

If you weren't too busy spouting memes you would had read the thread and had realized nobody was asking for roms.


Well, the title is misleading but as you said read the entire thread. I almost jumped on here and was ready to let you know as well but it turns out you are trying to get roms to PLAY online.

    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
