Shovel Knight: scrambled graphics

[mtojek]

Hi,

I'm trying to emulate the game using 64-bit libraries and box64. So far so good, audio works great, joypad too (I can hear audio feedback), but I can't figure out the graphics. It's gl4es and Trimui Smart Pro handheld.

Does it look like box64 issue or gl4es problems? I tried different gl4es libraries (Trimui, Portmaster's stardew valley and quakespasm), got same effects. Also checked box64 binary for rpi4, generic arm and rk3399 - same results, version: 0.4.3, I guess the latest main?

Cheers!

So,first: you create a ticket on box86 repo about a box64 or gl4es issue? You know there are repo for box64 & gl4es respectively?!

Now for the issue itself, it might be more gl4es than box64, but I'm not sure. I would need to try on my side. This version of ShovelKnight is the regualr version of the game?

👍

Now for the issue itself, it might be more gl4es than box64, but I'm not sure. I would need to try on my side. This version of ShovelKnight is the regualr version of the game?

It's version 0.4.1 of the game, 64-bit binaries. I can debug it further, but I don't have any more ideas. So far, I have checked different gl4es with the same effect.

I built the latest gl4es (disabled GBM for now in CMakeLists.txt) with:

cmake .. -DGOA_CLONE=1 -DNOX11=1 -DDEFAULT_ES=2 -DUSE_CLOCK=ON -DEGL_WRAPPER=ON  -DCMAKE_BUILD_TYPE=RelWithDebInfo;

I see the same scrambled effect, so indeed it might be an issue with gl4es. BTW @ptitSeb feel free to transfer it to the gl4es repo 👍

[ptitSeb]

Done.

[ptitSeb]

After a quick check, this seems to be a regression from v1.1.4 (so quite a long time). I'll try to bisect to see when it broke.

[ptitSeb]

Ok, found the commit. I have basicaly rolled it back, so it should works now (might brake other things tho).

[mtojek]

Thanks for working on this @ptitSeb! I must admit that the pattern changed, although we aren't there yet

Mmmm; the issue is: I don't reproduce your issue now on my side. It works on my test machine. Can you try to build the v1.1.4 and see if it worked for you (you might have to alter first line CMakeList.txt to set minimum version to 3.5...)

[mtojek]

It won't work due to bad assertions, already tried that as my starting point before diving deeper. This PR is essential.

BTW I'm not the only one facing this issue, saw this thread on reddit, same behavior observed.

[ptitSeb]

Ah I see. Well, without me being able to reproduce, that will be tricky anyway. I have a couple of Ambernick device, I'll have to try see if I can reproduce there...

(side note: I see that 32bits is not available on the "Brick": did you know that you can build box64 with box32 option, and get 32bits x86 binary support for box64 then, without needed any 32bits arm support)

[mtojek]

Let me know if you need any libs from the handheld or game libs. I can email them to you 👍

did you know that you can build box64 with box32 option, and get 32bits x86 binary support for box64 then, without needed any 32bits arm support

frankly speaking I'll leave it as a last resort. I hope this is just a simple/stupid bug somewhere in the GL implementation, nothing fancy :)

EDIT:

if there any switches or additional debugs that can shed some light, feel free to share, and I'll rerun the game.

[mtojek]

A few observations:

box64 with -DBOX32=ON fails with X11 errors?

LIBGL: Shutting down

I haven't seen this in 64-bit. I assumed that they work similarly (using wrapper around device native SDL2, see below).

I skipped one modification I applied for Shovel Knights 64bit - I deleted libSDL2-2.0* from deps, otherwise it complains about missing X11 deps. So, in Trimui Smart Pro, the default SDL2 is 0.3000.8. See listings:
