Can't get emulator to even start

[TheUnityGuy]

While doing everything as written on readme, nothing happens on index.html, blank page appears and no errors in console either. My directory tree (I have also tried to put zh-hans in i18n folder, buttons.zip and shader.zip in frontend, etc - same result):

Could you help me?

[nenge123]

that is the emulatorjs.com use new cores,

if you want to run, change emulator_4.99_19_Nenge.js => ${EmulatorCoresHost}/cores/${coreName}?v=${coreVersion} =>set your localhost cores path

                                    return T.FetchItem({
                                        url: `${EmulatorCoresHost}/cores/${coreName}?v=${coreVersion}`, 
                                        store: 'data-system',
                                        dataOption: {
                                            version: coreVersion,
                                            system:E['system']=='vbanext'?'gba':E['system'],
                                        },
                                        version:coreVersion,
                                        unpack:true,
                                        Filter(wasmU8){
                                            /**

                                            let mime = T.F.checkBuffer(wasmU8);
                                            if (!mime || !['zip', '7z'].includes(mime)) {
                                                wasmU8 = wasmU8['slice'](0xc);
                                                wasmU8['set']([0x37, 0x7a, 0xbc, 0xaf, 0x27, 0x1c, 0x0, 0x3], 0x0);
                                            }
                                            return wasmU8;
                                        },

[TheUnityGuy]

Alright, so if I'd like to embed your emulator on my own website, which version / files do you reccomend to use? The files specified to download in readme: common.min.js, extract7z.zip, libunrar.min.zip, zip.min.js, extractzip.min.js, emulator_4.99_19_Nenge.min.zip, /i18n/*.json, /frontend/buttons.zip+shader.zip, /bios/arcade.7z or something else?

As for now, I understand that I should be using cores from https://github.com/nenge123/emulatorjs/tree/0.4.23/cores and that's great, now which emulator version/files are going to work the best (I need PSX emulation the most if that's the case).

Also, thank you for your support ;)

[TheUnityGuy]

if you down emulatorjs 0.4.101 [Latest](https://github.com/nenge123/emulatorjs/releases/latest)

and... if I actually download emulatorjs 0.4.101, what should I change to make it usable for offline use without emulatorjs.com?

[nenge123]

that question .... some old cores hava errro, like mgba(gba.zip),

• old not have RTC in gbaRom,
• the new cores in (emujs.com) ,have RTC but lost fast fps play(fast_forward)

[TheUnityGuy]

Okay, let's say these old cores work just fine for my requirements (maybe use the compiled wasm cores from the webretro repository - I saw your pull on this repo). How can I use them with the latest emulatorjs 0.4.101? Is editing _0x29f314 to my host as you said before enough?

To be honest, it can be buggy and unstable. In my language there is a saying: "nikt nie będzie z tego strzelał" - "nobody's gonna shoot with it" 😅

tried it, following errors in console:

[nenge123]

.... I'm too long not update, pls wait my update or use this dafault (4.99_19)

if you use the newest cores in emulatorjs.com,some cores must need the network, the old cores not need network

like the psx.7z cores must visit (https://www.emulatorjs.com/api/v?name=psx) get hash key(headers data) to run start

[TheUnityGuy]

Okay, thanks ;D Awesome work btw

[nenge123]

fork 0.4.99_test

• emulator_4.99_19_Nenge.js

  async Wasm_Download(coreName, coreVersion) {
                      console.log('读取/下载 wasm file 若需加载指定核心(旧版)修改这里', coreName);

change your old cores

filetype: "application/octet-stream",
system: "psx",
timestamp:Nenge.date,
    type:"datalist",
    version:17})

[nenge123]

if you can make wasm to C find out this md5 function, the new core can not need the emulatorjs.com key

@TheUnityGuy the version 0.5.8 cores was decode download https://github.com/nenge123/emulatorjs/tree/0.5.8/ the newest cores!

Thanks!

if you want to run in 04.99_test

add <input> under the <canvas>

//add before Module,callMain()
            if(Module.specialHTMLTargets){
                I[1].assign(Module.specialHTMLTargets,{

                    '#canvas-mouse':T.$('#game')
                });
            }
//before Module,callMain() set hash
//'961a64459508e2435a5ef45e1fc816d232d57c66d2f3ea56d2af90bef14773f0'

                            if (Module['_get_content_crc'] && ejs_loader['newCoreKey2']) ArgInfo[2] = ejs_loader['newCoreKey2'];
//change

                            if (Module['_get_content_crc']) ArgInfo[2] = '961a64459508e2435a5ef45e1fc816d232d57c66d2f3ea56d2af90bef14773f0';

@TheUnityGuy perfect solution to hash value problems replace function make time lock,then hash key not need to change. https://github.com/nenge123/emulatorjs/blob/0.5.8/readme.md
