Local Achievements support ?

Validation

• I've read the FAQ.
• The Xenia build used is from the master branch (not MLBS/AlexVS/Canary/pull requests, etc.)
• This issue isn't for tech support (help with Xenia).
• If this issue occurs in a specific game, I've done analysis to locate the faulty subsystem of the emulator and a potential reason in it.
• I've checked if this issue hasn't already been reported.
• My device meets the minimum requirements: https://github.com/xenia-project/xenia/wiki/Quickstart#system-requirements
• (If building) I have read the building doc: https://github.com/xenia-project/xenia/blob/master/docs/building.md

Describe what's going wrong

Would it be possible to add support for saving the achievements unlocked locally, and maybe show a pop up when it is unlocked?
This would be similar to how RPCS3 maintains local achievements, and this would allow launchers like Playnite to show the achievements.
Maybe just saving unlocked achievements would be a good start and the pop up can be a separate issue.

Describe what should happen

Have a local list of unlocked achievements across all games.

If applicable, provide a callstack here, especially for crashes

There is unofficial support for achievements however it still requires some/a lot of work.
https://github.com/Gliniak/xenia/commits/stfs_profile_achievement_support
Thanks Emoose for most of this code.

Additionally saying "Achievement support" is quite vague in terms of what is to implement.

• SPA ✅ (That is part of xex that stores info about achievements or in certain cases SPA.bin that updates original SPA)
• GPD ✅(That is where player achievements data, settings and stats are stored)
• Achievements itself ✅ (With respect to regional/language player settings?)
• UI to show achievements progress (Only visible via dashboard at this point)

It would be great to implement them as it should be with support for profiles (GPDs are stored in profile file), but that step is most difficult. I don't have much experience with it yet, but for whatever reason mounted profile starts being corrupted more and more as changes are stored. It might work for like 25 games and then disappear.

In my opinion without profile support achievement support is quite useless. There is no profit of having achievements in account that isn't personal and in form that doesn't match what console does.

@Gliniak probably been suggested before, but what if RetroAchievements was used as the aggregator? Doing so would allow for out-of-the-box integration with a lot UIs/launchers/front-ends, including LaunchBox/Big Box which is quite popular. I can imagine the integration would be quite simple too, as the games on Xbox 360 are the ones driving the event triggers for achievements, as opposed to having to introspect direct memory like other RA implementations.

AetherSX2 is a standalone PS2 emulator (ARM-based) that implements this sort of functionality, without the need for RetroArch (unlike other RetroAchievements implementations). Could be useful as a reference?

@Gliniak have a weird idea, but i would like to make it known (i know it will sound ridiculous), considering that you mention that the achievements are linked to a profile and this profile is used locally, why not use an emulator that handles this data, for example, why not combine a steam emulator called goldberg emu or at least add the functions that this emulator developed (this emulator is open source), it has a support to create a user profile with a specific id locally, but I mention it because this emulator allows to get achievements locally because steam manages its achievements in a file called "UserGameStatsSchema_(id_game). bin" which contains what would be the data of each achievement, from this file you can dump the data to a file called achievements.json from which depending on how your achievements have been designed we could obtain 2 schemes of achievements that are by triggers or by statistics, of which I can give an example of how are your schemes

achievements by triggers:
{
"name": "ACHI_001",
"defaultvalue": 0,
"displayName": "BFA",
"hidden": 0,
"description": "unlocked ALL!",
"icono": "images\ACHI_001.jpg",
"icongray": "images\ACHI_001_gray.jpg"
}

achievements by statistics:
{
"hidden": "0",
"displayName": "BFA",
"description": "unlocked ALL!",
"icon": "6a05b669c14009ded04916a69d7646baf911d5e8.jpg",
"icon_gray": "8afadeb4b49d560605f0785df766eae1172af5f9.jpg",
"name": "ACHI_001",
"progress": {
"min_val": "0",
"max_val": "1",
"value": {
"operand": "statvalue",
"operand1": "STAT_001"
}
and when an achievement is unlocked this is stored in a specific directory where the achievements obtained are stored in this way:
by triggers
},
"BATTERING_RAM_ACHIEVEMENT": {
"earned": true,
"earned_time": 0
},
for statistics
}
"BEGINS_WITH_ACHIEVEMENT": {
"earned": true,
"earned_time": 0,
"max_progress": 80,
"progress": 60
}

maybe it is possible to dump the achievement scheme of xbox 360 games with a similar scheme to be able to make use of this feature and unlock achievements locally.
I know it's complicated to take this opinion into account, but it would be an idea for Xenia to be able to get achievements.

[Gliniak]

After a bit of consideration I agree.

It would be nice to already have at least basic achievement support + some external storage for them. What I mean by that.

In ideal world:

• We don't have personalized xbox profiles (YET)
• Achievement data is being loaded correctly to Xenia and game can pop it (ToDo: ImGui toast notification, but not sure how will it impact presenter)
• User have option in config to provide username+password to 3pp site that can aggregate them somehow in specific format
• After implementation of profiles user can pull achievements from site directly into profile

Issues:

• Not sure how to deal with achievements that store progress, because they must somehow store this progress locally?
• Xbox achievement data->3pp site JSON (probably) -> Xbox data "Translation"
• < probably some more >

@Gliniak
Hmm... idk if this idea keeps going, but the RetroAchievements site should be a good place to store the achievements externally, and would be a great addiction to the site.

[chris-calo]

@Gliniak @w400pedro yeah, RetroAchievements to me seems like the perfect place. Awesome uptime, free-hosting, leaderboards, good community willing to help build out data, the works. It's a no-brainer.

[Gliniak]

It's WIP but slowly, due to many circumstances

[w400pedro]

Got it, really good to know that the project keeps going, I know that's not an easy task, I'll be waiting :) take your time

RetroAchievements has recently released an emulator integration guide that may be helpful: https://github.com/RetroAchievements/rcheevos/wiki/rc_client-integration

Also underrated is that so many official Xbox 360 achievements are completely unattainable by default, or due to online being deprecated. RetroAchievements is a solution to that due to being community maintained perpetually. I do have to praise the service, and I hope you'll consider it. Either way, I look forward to seeing what comes of this c:
