This might be possible, I would need a way to test map changes on console
Would also probably need to build maps to the x360 engine limits

idk how Vphysics differs between pc and console either, so ported maps might not have physics

There may be a method where pc default and console default are compared, because I think it is only the conversion between their own engines between endians

is endian wrapper and compress with lzma

ok, so how convert this maps to x360?

Testing

Figured out a way to do testing, using Xenia
Turns out Xenia can launch the extracted default.xex, & other modded files
Using Xenia Canary since it patches the game a little

Requires changing the following settings in xenia-canary.config.toml:

# safety net
break_on_unimplemented_instructions = false
# console commands
# "-dvd" helps the game run
# "-game hl2 +map credits" sets the map to Half-Life 2's credits
cl = "-dvd -game hl2 +map credits"
# text rendering
d3d12_readback_memexport = true
d3d12_readback_resolve = true

Using cl="-dvd -game hl2 +map credits" loads directly into the end credits of Half-Life 2
Choosing maps by name makes things easier than I was expecting
Was dreading modding menus / replacing files to launch into maps
Also means testing is extra fast, I can make a shortcut to open OrangeBox/default.xex w/ Xenia

Team Fortress 2 can't run any maps, gives an in-game error saying: "Lost Connection to Game Server"
I don't know if that means the locally hosted server or some master server
May have to get my Xbox360 out and compare the unemulated game at some point

Engine Limits

I've started making a spreadsheet of how close Xbox360 maps get to the engine limits on PC
Right now they look pretty reasonable, I may already have some under the Xbox360 limits
Comparing against the equivalent PC maps is probably a good idea though

The Xbox360 limits I saw might be for the Xbox version of HL2
Or the Xbox360 limits are dynamic in some way

I am now comfortable enough with these tools to begin research
Map ports will likely involve cutting out a lot of lumps
This means maps will have limited functionality

Physics would require more reverse engineering than I am prepared for
There's also legal concerns (Havok Licensing)
I may have to copy lumps from existing maps in the meantime

Progress will be heavily reliant on motivation & time constraints
As of right now I am still actively working on mapping tools for the Titanfall Engine
There are also open issues for porting maps to Vindictus & Counter-Strike: Online 2

I am not making this a priority, but I will be a bit more active on this in future

It looks like this modder has already ported some maps
They have a discord link in the video description
Asking there would get you porting maps way faster than waiting for me to build a converter

I wrote a whole guide on how to do this:

• Compiling `valve.orange_box_x360` maps #154

The source code for the necessary tools is all available on GitHub
makegamedata.exe sources are legally questionable, but a 100% legal copy is attainable via Dino D-Day on Steam

Everything you need to port maps to the Xbox360 is out there, on The Internet
You don't even need bsp_tool for any stage of the process
Which is great! I don't want to maintain tools for multiple modding communities

bsp_tool is a small personal project, gathering public information and organising it
First & foremost, bsp_tool is for analysis

Not map compilation
Not map porting
Not developing tools

While bsp_tool could be used as the basis for a larger tool, it is not designed for that task
Python is nowhere near the performance needs of most mapping related projects

Writing bsp_tool in python allows for fast prototyping
Prototypes that can be re-written in faster languages, like C++
Like bsp2gltf, which is also a small personal project
io_import_rbsp runs in Blender Python, and might be the worst performing code I've ever written

Having Official Tools is a rare thing, and Dino D-Day/bin/makegamedata.exe is an Official Tool
It's not perfect
The workflow sucks
But it's better than a python script.

I will not be developing an extension to Source Engine maps to the Xbox 360
So, I've marked this issue as wontfix
This Issue is not directly relevant to bsp_tool or it's development

OK you work is fine i next work for my account

but is necesary convert .nav files too or byteswap

for l4d2 maps
for example
c1m1_hotel.nav to c1m1_hotel.360.nav

need the files?

According to the .bat files the Xbox360 Discord provides, makegamedata.exe can convert .nav
AFAIK the one .exe can convert all files needed for a whole game

L4D2 specifically? Left4Dead2 has a unique map map format
Listed in bsp_tool as "valve.left4dead2"

Copying the .dlls from Left 4 Dead 2's SDK might help (see #154 for the list of dlls)
There's more details in the Discord too

yes im decompile map hotel and i copy all textures and .pak from l4d2 folder to hl2 folder and compile map with hammer and finally run map form pc for now default but need more test for this

i need to convert .nav files manually too

thanks for all friend

just convert textures and models and ready .....
