This repository contains game patches for Xenia Canary.

Non-patch questions belong on the Xenia Discord server.

0. Prerequisites
   • Latest Xenia Canary experimental.
     • Patches aren't supported on master or outdated versions of Xenia Canary.
1. Download this zip.
2. Go to where xenia_canary.exe is.
3. Delete patches folder if present (backup if needed).
4. Open game-patches.zip and extract patches in the same directory as xenia_canary.exe. The folder structure should look like this:
   

   └─── Xenia Canary
       |  ...
       │  xenia_canary.exe
       |  ...
       └─── patches
               ...
               584111F7 - Minecraft (XBLA, TU0).patch.toml
               ...

0. Prerequisites
   • Latest Xenia Canary experimental
     • Patches aren't supported on master or outdated versions of Xenia Canary.
   • The right version of the game e.g. Title Update (TU).
   • apply_patches set to true (default) in the Xenia Canary config.
1. Open the .patch.toml file that corresponds to your game in a text editor (Notepad, VSCode, VSCodium, Notepad++, etc.)
2. Change is_enabled from false to true. For example, to enable a 60 FPS patch:

   [[patch]]
       name = "60 FPS"
       desc = "Description"
       author = "Author"
       is_enabled = false
   
       [[patch.be8]]
           address = 0x########
           value = 0x##

   becomes

   [[patch]]
       name = "60 FPS"
       desc = "Description"
       author = "Author"
       is_enabled = true
   
       [[patch.be8]]
           address = 0x########
           value = 0x##

If you see [Patches Applied] in the title bar then the patch(es) applied successfully.

Don't change the hash of existing patches. If your version of the game is different then the patch(es) need to be ported to that version.

• present_letterbox must be changed from true to false!
• Aspect ratio patches do not increase resolution!
• While most aspect ratio patches are 21:9 (3440/1440), they can be changed to other aspect ratios as well unless not specified or specified otherwise;
  1. Divide your monitor's resolution width by height (i.e. 3440/1440)
  2. Convert the result to hex.
  3. Change the value to 0x######## replacing ######## with the hex value.

Framerates above 60 FPS require vsync to be changed from true to false in the Xenia Canary config.

• Memory Breakpoints can be set in Cheat Engine or MSVC with emit_source_annotations = true. This will give annotations in disassembly.
• Cheat Engine 7.2+ includes Big Endian types, but they must be enabled;
  • Click Edit > Options > Extra Custom Types and check all of them.
• Go to Scan Settings and enable MEM_MAPPED.
• Change 'Memory Scan Options' to:

  	All
  Start	100000000
  Stop	200000000

  • This may change depending on the programs you have running.
• Once you find a value you can attach Cheat Engine's debugger to see what reads/writes to that address.
  This will show an xex address when a breakpoint is hit, although there is currently no way to set a breakpoint on execution within the Xenia Debugger.

• Cheat Engine
  • See setting up Cheat Engine
• Ghidra
  • XEX Loader
• IDA Pro
  • IDA 7 XEX Loader
  • IDA 6 XEX Loader
• Text editors:
  • Visual Studio Code
  • VSCodium
  • Notepad++
• Recommended but optional:
  • ESLint TOML plugin
    • See Editor Integrations
  • Visual Studio Code/VSCodium extensions:
    • Even Better TOML
  • To make things easier, put Xenia Canary in the directory that contains /patches and run it with portable.txt.

• Patch must be named Title ID - Game Title.patch.toml and be in /patches.
  For example, a patch file for Blue Dragon must be called 4D5307DF - Blue Dragon.patch.toml.
• If you are making a patch for a game that already has a file, then add to it*
  • Only exception being if you're patching a different module.
• Submitting patches:
  • No whitespace.
  • Lowercase hex for address/value hex, uppercase for title ID/hash/media ID.

0. Don't change the hash of existing patches. If your version of the game is different then the patch(es) need to be ported to that version.
1. Set log_level to at least 2 (default) in the Xenia Canary config; See How to use for location.
2. Run the game at least once.
3. Close Xenia Canary.
4. Obtain module hash/title ID/title name;
   • Search Ctrl+F for Module hash: in xenia.log
     You should see something like:

     i> ######## Module \Device\Cdrom0\default.xex:
     Module Hash: ################
     

   • Patches can have multiple executables/hashes. Only leave the hash(es) you're using uncommented: https://github.com/xenia-canary/game-patches/blob/95f51801048dc6e95675581e3fcf8fcdfc3e5544/patches/454108D8%20-%20Army%20of%20Two%20The%2040th%20Day.patch.toml#L3-L6

title_name = "Game Title"
title_id = "1234ABCD" # AB-1234
hash = "################" # Module the hash applies to (i.e. default.xex)
          # Can be an array if applicable:
hash = [
  "################"     # See above
]
#media_id = "1234ABCD" # Optionally you can add a redump link; Disc (Region): http://redump.org/disc/1234
#                        Can also be an array if applicable:
#media_id = [
#  "1234ABCD"          # See above
#]
# Title ID, hash, and media ID must be uppercase.

[[patch]]
  name = "Patch name"
  author = "Me"
  desc = "Patch description" # Description is optional
  is_enabled = false         # Must be false for PRs

# [[patch.*]]
#  For example, be8:
  [[patch.be8]]
    address = 0x82000000 # Tends to start with 0x8, always 4 bytes
    value = 0x00
#  Address and value hex must be lowercase.
#   string:
  [[patch.string]]
    address = 0x82000000 # Tends to start with 0x8, always 4 bytes
    value = "string"
# End of file newline
