Pull Request checklist

Note: these are not necessarily requirements

• I checked to make sure my submission worked
• I am the author of submission or have permission from the original author
• Requires update of the PS2SDK or other dependencies
• Others (please specify below)

Pull Request description

By having the ELF as standalone (instead of inside of a 7z file) it could be grabbed (streamed) and launched right away with no need to store it locally.

[uyjulian]

Extracting the elf to RAM out of the 7z would be a better option, since it does checksumming so can detect when corruption occurs (instead of silently executing corrupted data)

libarchive can be used for this. See ps2dev/ps2sdk-ports#174

Can a PS2 launcher be made that downloads and runs a link directly on the PS2? That would be a an awesome feature, not just for OPL.

Would be a lot simpler to just reference:
https://github.com/ps2homebrew/Open-PS2-Loader/releases/download/latest/OPNPS2LD.ELF
Instead of downloading and extracting from:
https://github.com/ps2homebrew/Open-PS2-Loader/releases/download/latest/OPNPS2LD.7z

PR makes sense to me, any objections if I merge?

I remember this from years ago:
https://github.com/Based-Skid/iLaunchELF

I think that was the idea behind it?.. never tried it.. no objections

That's the idea and there's already a PoC of that, but happens that when you build it with the latest SDK, it goes BSOD when launching, but the very same source worked fine in an SDK from 2019.
https://github.com/Based-Skid/iLaunchELF
I added the function to download to RAM and launch ELFs to XEB+ this very same week and struggled trying to find why it didn't launch it until I went and tried compiling iLaunchELF, an already known to work application, with an older SDK and a modern SDK and comparing the results. That's when I knew where the issue was.

[rickgaiser]

Can this stream https also, or only http? Becouse the github downloads are https only if I'm not mistaking. In that case this pr would not help your goal.

..offtopic..
The ps2sdk is constantly being worked on. I understand it can be difficult at times, but your complaint is too general. The ps2sdk cannot provide backwards compatible support to all apps in existence. We can help to find/fix the issue, but you'll have to point to a specific thing that the ps2sdk does wrong.

[HowlingWolfHWC]

uyjulian is making a launcher that supports modern web and https, but I tried it personally with an http link in my tests and files hosted in another server.

That ilaunchelf code is probably incompatible with latest SDK.

Daniel Santos was able to download from GitHub IIRC with some sample he made for Athena (see CuRL port on PS2SDK)

[HowlingWolfHWC]

Regarding the issue of iLaunchELF, here's what I said to uyjulian:

Original iLaunchELF binary: https://pixeldrain.com/u/kJZow2HP
Source: https://github.com/Based-Skid/iLaunchELF

My updated one + source:
iLaunchELF-modern test.rar
https://pixeldrain.com/u/tcGjtVga

Seems like the new SDK doesn't like launching ELFs from the internet...
My fork updates the source so it can be compiled in the modern SDK, plus, it changes some links to active ones.

Every link in the iLaunch-Demo is offline, but they can be replaced via HxD
I did replaced a link with HxD in the old one and works (Press SQUARE to launch it), while the very same link in the updated one fails.
https://pixeldrain.com/u/M7sz2JJa

The thing is:
iLaunch has his very own ELF loader in it's source
The one compiled with an older SDK works (tested by replacing a dead link with a new one via HxD)
I forked the same source, remove the need of bin2s, updated the links and compiled it in a modern SDK... it fails.
So, the issue is somewhere in the SDK, not in the source of it. And, it is NOT in the loader from the SDK, since it uses his own one.

He said that he's working on something that might fix it:
Quote:
it will be possible to load from archive and from new HTTP versions https://github.com/ps2dev/ps2sdk/pull/488

[HowlingWolfHWC]

Afterwards I set up an older SDK, compiled iLaunchELF and it worked out of the box...

Maybe VTSPS2-HBDL (iLaunchELF fork) can help?

That fork doesn't launches an ELF from memory. Instead it launches it from the MC.

PR makes sense to me, any objections if I merge?

I d rather remove then .7z variant, currently there way too many files attached to releases.

I agree, there's too many files already:

They are all double. 1 with and 1 without version number.

@HowlingWolfHWC when and how will this extra file be used? You're referring to a tool @uyjulian is making, but he wants to use .7z files. And you've only tested http, but this adds an https file. So I'm lost as to what the usecase of this PR is.
If it's a non-existing usecase that would perhaps be nice in the future then it's only adding bloat for the time being. Perhaps it's better to test on your own github branch first, then add the file later if it's really needed?

[HowlingWolfHWC]

I ran tests of this via a HTTP proxy on my own fork.
The request is made from a HTTP website and it retrieves the file from HTTPS.
Right now, there's no proper app to use it. In fact, I had to hex edit an already compiled one 'cause it fails to work properly when compiled with the latest SDK.
I've made stream-like plugin support in XEB+, but is not functional due to what I stated before.
I'm yet to update again the SDK since I'm waiting for @uyjulian to let me know when his pull request to the SDK gets merged.
Once done, I will test if my implementation works.

Any chance for an ELF with a version number?
E.g. OPNPS2LD-v1.2.0-Beta-2199-200eaa7.ELF.
