[Box86] [Wine] Realm Grinder

[Kiiro-Yakumo]

Hello.

I have a bit of a problem with a game and out of ideas what could be the cause. I have tried both RPI4 and RPI5 as hardware, Twister OS on RPI4 and Raspbian Bookworm on RPI5. From what I understand Twister OS has Wine 5.13 so I took into the account that maybe for some reason it's "not enough" for this game. On Raspbian on the other hand thanks to recently found instructions on this github I was able to put Wine 7.1 and 9.22 back and forth after misreading the cause of certain things but both versions were tested separately. The game should work on "just Wine" on x86 PC I believe, however I haven't tested it heavily.

As for the problem, the game technically starts and works from its own point of view but there are serious problems preventing player from doing proper actions. The list of buildings on the right side is most of the time almost empty with only last building visible, upgrades probably don't work properly, Mana bar is not visible at all and so on. From the Terminal I couldn't determine any entry that would openly scream "I don't have this thing" to pinpoint the problem. There seems to be some entry with problems about sound but honestly that part is a low priority as the game basically has only few music tracks looped without sound effects.

I have tried installing DX9 and vcrun2005 I think through Winetricks, the first as the game probably rides on it if anything, the second actually not sure, back in the day it was somewhat "classic" one to try if something does't work. I have tried DXVK as well but it seems that box86 can't utilize it currently if I understand correctly.

If there is some information or screens needed, I will try to provide them as well.

Thank you in advance and have a good day!

EDIT 1 - Ah I forgot, the game itself is available here:
https://store.steampowered.com/app/610080/Realm_Grinder/
It's free to play and it can be used without Steam for sure.

Box86 support DXVK, but the RPI4/RPI5 probably not.
You might need to use MESA_GL_DRIVER_OVERRIDE=3.2 to force OpenGL to 3.2 for Dx9 game to work.

I have re-checked the statement, you are right, Box86 can do it, RPI4 seems to be not supporting it at least in current state (assuming it can be achieved one day that is).

I have tried both these parameters separately and both at once:
MESA_GLSL_DRIVER_OVERRIDE=3.2
MESA_GL_DRIVER_OVERRIDE=320
as well as similar one you made me remember as a trick to a Linux game or two on x86_64 PC, again used separately and both in ongoing tests, I think I have exhausted at least most if not all combinations of above two and these:
MESA_GLSL_VERSION_OVERRIDE=3.2
MESA_GL_VERSION_OVERRIDE=320

There was one time when bottom bar with buttons and "basic info" was kinda visible but I couldn't replicate it a second time currently so for now I think of it as a fluke of sort. Unfortunately Steam Store page doesn't specify DX version required for it. I can only guess that since it requires - according to Steam Store page - Windows 7 as minimum, then DX9 would be bare minimum for this as DX 8.1 ceased to exist with Vista I believe?
