iOS version black textures issues

[WeedyWeedSmoker]

Hi @m4xw, I thought for a long time that the iOS 64-bit version always had some "black texture issues", but it seems that's only happening with the main iOS branch… https://forums.libretro.com/t/retroarch-1-8-5-certain-textures-are-black-mupen64plus-next/27308/9

This fork from @jet082 actually works mostly fine : https://github.com/jet082/mupen64plus-libretro-nx/commit/a7adaf2e253a445081d5b450ef063f62e4dd5b8d

I really don't know how to help but the official RetroArch iOS and tvOS .ipa releases use this commit and not the latest version from your main iOS branch…

Thanks!

I can test this. It’s been a while but can you refresh my memory. Is there an ipa ready or does the rebase branch need to be compiled?

You need to compile the branch and put the library into the uncompressed RetroArch.ipa.

Hi m4xw, for me the issue still persists. I compiled both branches with identical results in Yoshi's Story, and in Gauntlet Legends, the HUD display is still garbled and unsusable. Sorry for no better news. In Retroarch the core is called Mupen64Plus-Next (2.3-GLES3 git)

Looks like you ahead on me for this one. I'll take your word that this doesn't work versus breaking out my macbook to clumsily compile this. Thanks for trying @m4xw! Hope to one day see this fixed.

Not sure if this is relevant, but https://github.com/Provenance-Emu N64 Mupen core seems to have had the same issue previously, but with one of their recent updates it has been fixed. Unsure if there's information within their github that could be helpful here.

Hi, can someone try https://github.com/libretro/mupen64plus-libretro-nx/commits/ios

[m4xw]

Getting closer to the root cause..

Wow great job @m4xw ! There’s still a few textures missing, but the game is more playable than ever! Tried on RetroArch 1.11.1

I hate my life

Also just to be clear, the way i ""fixed"" it isnt proper, but this confirms the issue at hand so I will get this fixed properly.

Both IOS and emscripten have the same restriction not allowing textures that arent power of two for some reason, even tho it should get a GLES3 context. So expect some extra bugs that arent present otherwise till then, but this should cover most texture cases

Hi, having major codesingning issues, still trying to resolve them...

Hi, having major codesingning issues, still trying to resolve them...

Finally, some testing (LOD disabled):

• own compile and pre-compiled version A: heavily broken, more broken than before
• pre-compiled version B: best results so far, Gauntlet Legends clearly better, Yoshi's Story looks very nice so far, HiresTextures e.g. in Super Mario 64 still severely broken Thus I opt for version B ;-).

Cheers!

Edit: Identical results with LOD enabled in version B.

Yes m4xw, I am still on Discord, which channel?

Here are some shots - don't be surprised: These are shots from MacOS Catalyst running Retroarch iOS absolutely seamlessly on my Apple M1 Silicon besides some minor hickups (e.g. no save states option) - but the gfx output is identical to that of the iPad, so its fun to test!

First some screenshots without hires:

Yoshi's World - quite perfect!

Super Mario 64 without hires

Gauntlet Legends - minor problems in the boxes, but much better than before

Zelda OOT - just fine

Next some hires pics.
