I am not sure why my thread got closed. Please if you have nothing worth contributing or helping or even constructive criticism please stay off of my thread.

Invalid Header Check - This may want to stay intact just in case you don't want to crash Halo 2 because some data does not match up.

Its a easy reversal to skip the check.

It is similar also with the Data check. But instead it checks against multiple sections in the file. Here is the start of the check where you can force it to load the map without any problems.

Also I found some stuff for a similar Halo 2 CE project lead by KIWIDOGGIE over at his website and halomods.

All credit to his team for this.

Pingo posted that for the latest update of Halo 2 halo2.exe+7eb5; is the address for the reversal.

I will continue to post more research. The Halo 2 exe is protected by isDebuggerPresent and some other function.

The reason why your previous thread was locked, is because it seemed like you were a troll. Many projects like this have occurred before (Kiwidoggie, and E3p0, but both of them are banned for misconduct on the forums).

If you believe the original thread was locked by a mistake, I suggest you send a PM to a moderator or admin asking them why it was locked, and prove that you weren't trolling.

[Inferno]

That user name is something I would come up with.

People just love to hate on H2V on this forum for no reason. You don't need to prove shit, you've provided enough.

Kiwi is banned from here, I mean WTF? He's one of the few people working on H2V.

[CodeBrain]

If you really want to know why Kiwi was banned, have a look:

http://www.modacity.net/forums/showthread.php?t=10225

http://www.modacity.net/forums/showthread.php?t=9923

Those are the only reasons I could believe why Kiwi was originally banned. However, there ARE posts/threads after those specific threads, so I don't know if these were the original cause.

What did he provide in this thread besides some useless text, and a name that screams troll? Nothing at all.

There are good reasons as to why Kiwi was banned from this site. I personally can't stand him because he lies about a lot of stuff. For instance, his tag extractor that he deleted the source code to because the tags were boring and "couldn't be used".

Theres a reason, this site changed its name FROM h2vista.net to modacity.net...you idiot.

Kiwi's a friend of mine, but he does stuff that really annoys me.

[FreelancerIsFree]

This site is not very "user-friendly" it seems. I have talked to kiwi and he seems like good people. It may not agree with this sites "no cheats" rule but other than that it seems like none of the "cheats" that he did create were ever released. (Or I can't find them, or anyone who has them)

There is also some tool that his team was working on called "Choppa" it has most of the tools used to mod/RealTimeHalo Halo 2 for Vista. There is a Meta Extractor in it from the screenshots he has shown me. (Is that what you were talking about ShadowSpartan?)

And so far everything kiwi has said has been true. I'm not taking sides but just looking at the big picture. I think it was in right power for you to ban him from this site, for breaking the rules. But for you to label a new member as a "troll" is not a very good "welcoming" message.

OK back to the research.

This is the player control globals, this has a very similar layout to Halo 2 for the Xbox. (Thank you xbox7887)

No it is not. Tag extraction is not the same as "meta" extraction.

But for you to label a new member as a "troll" is not a very good "welcoming" message.

If you don't want to be labeled as a troll, then pick a unique username. Explain to us where your username came from and why you chose it, if you are indeed not a troll.
