@MrVicho13 I have successfully figured out how to make custom maps that can be toggled.

I have modified files for this map. The Hyrule map is disabled when the game starts up, and it can be toggled with a trainer.

In the castle.ymap change these values at the top of the file.
<flags value="1"/>
<contentFlags value="65"/>

In the mainifest.ymf, you need to add data to the Map Data field so it looks like this.
<MapDataGroups>
<Item>
<Name>castle</Name>
<Bounds>
<Item>hyrule_col1</Item>
<Item>hyrule_col2</Item>
<Item>hyrule_col3</Item>
</Bounds>
<Flags/>
<WeatherTypes/>
<HoursOnOff value="0"/>
</Item>
</MapDataGroups>

I am not sure if this is necissary, but I think that it is possible that it is.
For all of the entities in castle.ymap, change the flags value. Instead of the value being 384, it will look like this.
<flags value="1572872"/>

@nkjellman Nice discovery, thanks for the explanation.

@MrVicho13 No problem. :)

But I am wondering, did you use the tool that converts Five Reborn maps over to ymap/ytyp? Do you have any other maps on the way? Maybe even the conversion of your older maps to be DLC?

@nkjellman Something like that, yes, indeed.

@MrVicho13 I hope that these tools become public soon. That way we can get more maps on here like this one.

What program do you use to make the map?

@Johnnyp3010 Pretty sure all they did was figure out a way to import it from the latest Zelda.

Totaly AMAZING the View from Michael's house !!! TOP of the TOP mod : magicaly an another dimension ,dreamy immersion , perfectly stable even with 13 meters level higher !!!
----Can you tell me how do you do to convert .obj or another 3d model to .ydr files ???? It is so creative , i have thoussands of 3d models who are waiting to be converted !!!!! THANKS a lot for your amazing ART from France :)

hey, this is not for this map but for your liberty city map, where is it, i cant seem to find it

I was able to copy the folder into update/dlc packs, but there is no update.rpf/common/data/, or an mods folder. I have Open IV. Do I need something else to make this work. Basically I'm asking how do I install this mod so it can work?

@MrVicho13 Oh very awesome map!! Good work!!(:

OK I did manage to get the dlclist.xml open & edited. But the only way to do that is to export it. How do we get the updated dlclist.xml into update.rpf? I do realize Rockstar tried to shut down Open IV so this might not even work anymore & I'm wasting my time. Sorry to post so much I was hoping I could get this mod to work. Any assistance would be greatly appreciated.

Yo! Sorry bro I couldn't find another way to contact you other than to comment; WHAT HAPPENED TO ALIEN CITY?! :( I Was using it in a machinima and now the file has gone! D :

@mrvicho13 can you invite me to the liberty city discord server
