Errors in OMORI

g_f_y

Game build: OMORI v1.0.8 (8879120)
Summary: Multiple errors encountered when trying to run OMORI. These errors result in game unable to boot. There are some fixes to prevent issues.

Details:

Error: Uncaught Error: readFileSync: Failed to read /www/js/plugins/JoiMV.OMORI
Cause: JoiPlay plugins are not being excluded from game decryption process
Fix: online/local patch

            "author": "[ g f y ]",
            "comment": "Exclude JoiPlay plugins from OMORI decryption",

        }
    ]
}

Error: Uncaught Error: readFile: Failed to read OMORI/CUTSCENE.json
Cause: game issue, it’s trying to read a file it didn’t create
Reference: /www/js/plugins/GTP_OmoriFixes.js
Fix: either patch/override the script, or add the required file (the latter was easier for me)

Error: Uncaught Error: Java exception was raised during method invocation (line 37291 of nwjsapi.js)
Cause: NWJSAPI’s loadYAML method fails to handle YAML files that lack actual data and consist only of comments
Fix: temporary local patch, the method itself should probably be fixed

    "rpgmmv": [

            "key": "var jsonData = NWJSApi.loadYAML(JSON.stringify(Buffer.from(data).toJSON()));",
            "value": "var jsonData = '{}'; try { jsonData = NWJSApi.loadYAML(JSON.stringify(Buffer.from(data).toJSON())) } catch(e) { console.log(data) };"
        }
    ]
}

Sample of failed YAMLs:

Error: Incorrect scaling
Cause: YEP Core Engine plugin is causing issues with the game canvas scale
Fix: temporary local patch, PluginsOverrides probably should be updated

    "rpgmmv": [
        {

            "comment": "Fix YEP Core Engine Real Scale",

            "value": "let e=PluginManager._scripts;if(e.includes(\"YEP_CoreEngine\"))try{Graphics._updateRealScale=function(){if(this._stretchEnabled){this._realScale = Math.min(window.innerWidth/this._width,window.innerHeight/this._height)}else{this._realScale=this._scale}}}catch(e){console.log(e.stack)}"
        }

A quick note to the last (№4) bug:

PluginsOverrides.js stopped being injected in JoiPlay 1.20.530, on 1.20.520 it’s fine
This scale fix applies to other games as well:
Without fix With fix

In Stars and Time v1.0.6.3 (GOG installer, use Inno Setup Extractor)

Stellinavra v1.0.2 (NSFW)

Edit: Though, it can be rewritten differently, because this method originally from rpg_core.js, and can be changed not only in YEP CoreEngine (e.g. in same Stellinavra it’s also overridden in OkoOverwrite.js)

Oh, so the plugin override was injected by JoiPlay. I tried to find it before and thought it was part of the game itself.

Also, that’s a lot of patches were needed just to make Omori playable. I remember playing Omori on JoiPlay, which was ported by VienDesu, a team that also ported an NScripter game to Ren’Py. It worked fine after I fixed the plugins.js due to that issue been reported a while ago and enabled the ‘allow external modules’ option. I think they mentioned adding many patches just to make it work.

Regarding Omori, I wonder if Mod Loader work with JoiPlay? For example, if I want to apply this mod Reverie, is it possible? 🤔

Not so much, in theory 1st can be added to the online patches, the 3rd and 4th are fixed in JoiPlay itself
(idk about the second one, either fix it based on the game script, or just ship this file in JoiPlay)

Grimm_Knight74 Regarding Omori, I wonder if Mod Loader work with JoiPlay?

Did a little tinkering with it and got stuck on the main game loading moment
I think it’s better to create a separate thread for this when I have time, but I’ll wait for the plugin handling system and this thread to be fixed first

g_f_y added to the online patches

Ahh, okay 👍
I noticed that some of your patches, which you reported a while back, have been added to the Online Patches.

g_f_y think it’s better to create a separate thread

Please create one if you’re able to get it working, as MV/MZ games, in my opinion, are designed to be mod-friendly! 😆
