Yanfly Save Core does not work HTML5

[TheUnsaid]

Here's my game as proof.

It always says that the save is from a different game.

That's because when you add a plug-in you *MUST* start a new game. Old saves will not work. This is because they add variables which the old saves will not recognize. So yes, to the engine, when you add that plug-in it thinks it is from a different game as it is from a different game, one without the plug-in.

I did start a new game. My game isn't that long, so I usually start a new game to test.

But did you delete the old saves or move them to a new directory? If they are still there it will throw off the system. As it is, it looks like it is finding an old save that doesn't match what it wants so it is marking it as for another game based on that screenshot.

Please try for yourself as you're a completely new user. It's very accessible and won't take your time.
I swear even fresh runs cause that error.

The thing is, I use that plug-in and it works for me. So it is something else causing it.

For HTML5 as well?
I have no problems on Desktop mind you.

@TheUnsaid There appears to be a check against the title of the save and the title of the game during the save game verification code. I am not sure if that was added in recently or not, but once I removed the check everything worked as normal. The code that follows is a quick-fix and has the title check removed. Copy and paste the code into a '.js' file, plop it into the plugins folder, and add it as a plugin. That should fix the issue. Probably.

DataManager.isThisGameFile = function(savefileId) {
    var globalInfo = this.loadGlobalInfo();
    if (globalInfo && globalInfo[savefileId]) {
        if (StorageManager.isLocalMode()) {
            return true;
        } else {
            var savefile = globalInfo[savefileId];
            return (savefile.globalId === this._globalId);
        }
    } else {
        return false;
    }
};

EDIT: Or if you don't want to add the above as a plugin, you can edit line 273 and 274 of '/js/rpg_managers.js' :

DataManager.isThisGameFile = function(savefileId) {
    var globalInfo = this.loadGlobalInfo();
    if (globalInfo && globalInfo[savefileId]) {
        if (StorageManager.isLocalMode()) {
            return true;
        } else {
            var savefile = globalInfo[savefileId];
            return (savefile.globalId === this._globalId &&
                    savefile.title === $dataSystem.gameTitle);
            // Remove the '&& savefile.title === $dataSystem.gameTitle'
            // The line should appear as 'return (savefile.globalId === this._globalId);'
        }
    } else {
        return false;
    }
};

@Ossra
Can I hug you?

So it wasn't a save core problem. It was a basic RPG Maker problem.

@TheUnsaid Well, there is an issue going on somewhere, since that check has been around since at least MV version 1.2. But, for a quick-fix you can at least use the code above.

 

[SeaPhoenix]

I think the game title check wasn't initially in MV, but added at some point to prevent the issue of different RMMV games that are being played on the same browser from accessing the same save files. Poryg explains it here when someone asked why the save files on the browser no longer worked when they changed the title of their game: https://forums.rpgmakerweb.com/index.php?threads/por_savecore.93294/page-2#post-867730

The save files for MV web browser games are stored in localStorage. This data storage is segregated for each domain, so if you only host one MV game on your domain then you're fine to remove that check as described above. However if you have more than one MV game on your domain then you need that check.

Don't games have a unique identifier though?
"
savefile.globalId === this._globalId
"
What's wrong with just relying on that?

 

[Ossra]

@TheUnsaid The 'globalId' is always -- for now at least -- set to 'RPGMV'. So there is no built-in, unique identifier for each game. YEP Save Core adds in a unique identifier, though.
