Argh - the "emscripten" base for the webassembly doesn't build on 32 bit raspberries ?... Can someone please provide me with the actual web-emulator files:

ex16mu.data x16emu.html x16emu.js x16mu.wasm webassembly/styles.css webassembly/main.js

and maybe what's needed to mimmic the "try now" button?

You can get the webassembly assets here https://github.com/sebastianvog/x16-emulator/releases/tag/1.0.0-beta.4

Extract that to a folder and run a local web server using this folder as root directory (for example running python -m SimpleHTTPServer 8080 within this folder )

Now you should be able to run the emulator with http://localhost:8080/x16emu.html

To load a PRG, you need your  apps assets in a folder  and a manifest.json file (for example in your current version looks like as generated https://www.commanderx16.com/emulator/40-brixx/manifest.json )

 If  have your game files in a brixx folder and also put the manifest.json in there, you should be able to launch the game in a browser with:

http://localhost:8080/x16emu.html?manifest=/brixx/

If something in the emulator startup doesn't load the javascript console might give some insight, if a file/path was not found.

ok, thanks a lot! I did that - and it works here, while it didn't in the official web emulator. Strange...

So I assume the only difference  is that I didn't provide a manifest.json, instead relied on the generated one. I'll now retry to upload V0.8 with a ZIP file which includes the manifest.json.

Unfortunately this didn't solve the problem. So:

- testing the same zip file content on a web emulator on my Raspian hosted webserver works

- on the official web emulator it doesn't.

Strange thing is: everything I'm loading into VRAM via vload() works. Everything else with cbm_k_load() doesn't.

I've reverted back to V0.7 again.

Any ideas? I'm scratching my head now...

Perhaps the generated manifest is slightly different,  did you happen to look into the browsers javascript console and see if any errors were reported ? If you upload your 0.8 again I could take a look and verify if all assets get loaded, at least from the web-emulators perspective.

What are you using cbm_k_load for? Are you loading data to banked RAM? If you are just loading everything directly to VRAM, might as well just use vload.

Otherwise, you may want to try taking a look at the machine code that cc65 is generating, make sure it is calling the Kernal LOAD function correctly. It may be worthwhile to roll your own assembly code to call the kernal and handle all this low-level business and link that into your C code.

Ok, I've uploaded V0.8 again. I now included a manifest, so that should be fine now. And it works on my own installation of the web emulator. I'll check the console now...

I'm loading music file segments into banked RAM. I will try to check the generated assembler code, maybe I can see something there.

@SebastianVogesLooking at the console output I might have spotted something: the generated manifest.json doesn't contain the music files. Looks like the included manifest was ignored. Does the manifest generator only include specific file extensions? Like BIN, PRG and BAS?

The music files have "SMF"

Aah, looks like that is the issue. the backend likely overwrites the manifest you included . And as you say it seems to ignore SMF files when generating the manifest . @MattGrandis will have to help us here.

Looks like it. Just tried to download a SMF files like you showed further up for the manifest:

https://www.commanderx16.com/emulator/40-brixx/brixx01.smf

Not found... So quick-fix would be to change the file endings to "BIN". If it's a hassle for @MattGrandis to fix this, then I'll go that route.

I've used BIN for all loadable assets, PRG for all executables, and not included any manifest in my zips, and everything works correctly.

I have notices that not using PRG for executables does not work, even if you explicitly put the filename to execute in the upload form. Once it gets to the emulator, it is checking the extension to determine file type and rejecting anything without the PRG extension as an executable. It may be doing the same check for BIN.
