Hey, so i've been trying to use arsenic but i don't really have much of a clue. i'm trying to see if i can port some custom variants of stock maps with modded weapons and maybe try to port my own Multiplayer maps to Halo on console. Any help (This is actually useful in my country because many people still play classic Halo 1 xbox on the original xbox)

Hey. Sorry for the late reply. I don't get on here much. Maybe every 6 months now.

To use Arsenic you must first create a base tagset from the original Xbox maps.

Make sure upon your first run of Arsenic you properly set your Xbox maps and tags directory, and your CE maps and tags directory. Make sure you have a base tagset of all the original maps from both versions.

In Arsenic you will go to File > Import > Xbox Maps. This will take at least 10-15 mins and will export the tags from the Xbox version of the maps.

Once you have this base to work from you can import CE maps (File > Import > Map.) Arsenic will decompile them and convert them into Xbox tags. From there you can open scenarios and add the customs tags from the imported maps to those scenarios. Custom maps do usually work. But keep in mind that the original Xbox has very limited RAM. Assets need to take this into consideration.

Once you have a scenario together that you're ready to compile you will go to File > Export > Xbox Map > Compressed. And you will choose which of the original maps you will be replacing. Keeping in mind that when you replace the original map on your Xbox console that the name must match.

Back in the day I was able to convert most maps without any trouble at all. Within reason of course. Most of the Halo 2 remake maps I've converted work amazingly. Custom skies usually work. Custom HUD elements take some effort... but if you have a working knowledge of how to do it in CE, you should be able to figure it out for Xbox.

I hope this helps at least a bit. I'm nowhere near an expert and it's been a long long time...

EDIT: Forgot to mention as well... make sure you're using the latest version I released on here a while back. It has some important fixes and has been updated for more modern systems. It is the only version out there that is capable of working with Campaign maps as well. I took on the task of porting Lumoria long ago... got pretty far. Unfortunately, I lost those files on an old PC some time ago. Good luck!

This may be an old thread, but I'm just gonna throw this out here.

The 3.0.0 update of Arsenic is broken for me. When I try to load ANY of my Halo Custom Edition maps, both MP and SP, I get an error saying "Specified Cast is Not Valid". I have no idea how to fix this.
