There is no support for XBLA digital titles atm, right? |
|
Right, disc based games only so far but I can have a look on how to support
XBLA games if possible.

Any compressed disk format is nice I guess, but what are the upsides and downsides compared to (say) chd, xz or aaru? |
|
ZArchive is based on zstd which is faster (both compression and decompression-wise) than LZMA / LZMA2 (xz). ZArchive sounds like a very good middleground as we benefit from compressed disc-images (I have not tested nor implemented XBLA yet) while provide similar performance to non-compressed images. |

@Rex000 the PR being not merged yet, this is the expected behavior. Are you running a custom build including this PR ? |

Why are my comments being marked as off-topic and spam? |
Tech support doesn't belong on GitHub. Use the Xenia Discord server for that. |

Thanks for merging ! |
Thanks for making this :) |

One thing the zar format does in Cemu is allow for base game, update, and DLC to be packed into a single zar file. Then, the updates and DLC are automatically applied when loading, bypassing the install step. As far as I can tell, this is not implemented here--is that correct? |
|
@remote009 correct |
ZAR is the new compressed format adopted by Xenia-Canary. More info here :xenia-canary/xenia-canary#165 It's also way easier to launch XBLA games converted to .zar

Excuse me but can I ask why this awesome feature is still not implemented in the stable release (I mean in the master branch / the emulator that the end user downloads from https://xenia.jp/download/ ) since May 21 of 2023?. It's really very unlikely that one can find out that this brilliant feature exists in Xenia, and even more unlikely that one figures out that it is only implemented in the xenia-canary experimental release... (or at least that is what I assume since loading a ZAR file in the master branch's release it crashes Xenia) Brief history about how I got here: I discovered this PR because it was mentioned at the very end of a long article about compression formats for emulators, and no body reads that, only few freaks like me that has enough time to investigate and to read bibles about compression optimizations for collecting game disc images... I'm nobody to say what the developers of Xenia should do about anything, let no one misunderstand me, but I love this feature and I humbly think this should be available for all end-users through the normal/stable/latest release of Xenia, and also that Xenia developers could pump visibility and adoption for this awesome zar feature!. I wrote this request because I previously kept my XBox 360 discs extracted and compressed in RAR5 format (which has better compression than ZAR, but it has the disadvantage that I need to extract the RAR file to be able to load the game in Xenia), and I discovered this feature of ZAR format support randomly, so I would like other people to be able to enjoy it directly from the stable version of the master branch. |
No people do read that wiki. You can also find out about these sorta PR changes from Emulator subreddit on Reddit.
I don't know, the "stable" Xenia (Master) should basically be seen as base Xenia, while yes Xenia Canary is "experimental" it's still stable, both are work in progress and unfinished which will take years if not a decade to play every game, even then awesome people will keep showing up and improving on the previous work (see other emulators like PCSX2). |
Maybe experienced or advanced users like you, but Xenia (master) is the one that is provided through the official website, so it is the one that common or casuals users like me finds, downloads, and ends using it. There is no mention to Xenia-canary on the Download section of the Xenia's website, just a hyperlink to Xenia's (Master) repo on Github. Then I think probably many people don't even know about Xenia-canary existance. EDIT: I found a mention on the QuickStart guide. Thanks for your participation! |
Reddit, Twitter, YouTube, TikTok exists. on PCGamingWiki I've made quite clear that Canary is what everyone on those platforms and discord recommends. Anyways this is off topic |
It is what i search and dream for x360 :) Thanks @rtissera for adding this new feature :) |
This PR adds support for loading ZAR (ZArchive files) of a decrypted dump of XBOX 360 game.
The process is basically to dump your disc, extract files using your favorite tool, and create a ZAR file from it using ZArchive tool.
ZArchive is a format created by @Exzap for Cemu to store Wii U dumps originally (WUA files). It is very lightweight and uses modern Zstd compression.
This PR implements ZArchive supports through zstd and zarchive dependencies as third-party libraries, premake build support and full C++ VFS implementation for this specific kind of device.
I have personally tested it on around 60 games without noticing any behavior difference or performance hit between a decrypted folder and a ZAR file.
Comments, enhancements, and possible mistakes are welcome.
