Unreal Tournament 2004

I think the native version of UT2004 is not for arm systems but it's the job of box86 to launch it. What i'm missing ?

Something like box86 that would translate x86 bytecode to ARM.

Nash

Box86 lets you run x86 Linux programs (such as games) on non-x86 Linux systems, like ARM (host system needs to be 32bit little-endian).

Is my Retropie image for Raspberry 32 or 64bits ? How can I know that ?

Did you use the RetroPie image for installation ? Then it's a 32bit system. The getconf LONG_BIT will tell you if you're running a 32 or 64 bit system.

@mitu
Yes I used Retropie Image. The command confirms I'm on 32bit.

I have reinstalled box86 following this guide https://pimylifeup.com/raspberry-pi-x86/

Same error :
Error: loading needed libs in elf /home/pi/RetroPie/roms/ports/UT2004/System/ut2004-bin

Are you launching the game via box86 ? It doesn't seem like it.

Here is my actual script :

if pgrep xboxdrv; then sudo killall -s SIGKILL xboxdrv > /dev/null; fi
cd
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
--detach-kernel-driver \
--config /home/pi/RetroPie/roms/ports/PiboyXRS_unreal_xboxdrv.cfg \
--ui-axismap X1=KEY_Q:KEY_D,Y1=KEY_S:KEY_Z > /dev/null \
&
cd
/home/pi/box86/build/box86 '/home/pi/RetroPie/roms/ports/UT2004/System/ut2004-bin'
sleep 10

sudo killall -s SIGKILL xboxdrv > /dev/null

Before the elf error there is "Box86 with Dynarec v0.3.7 ..."

mitu

@Nash Ok, so it's not working with box86 either.

EDIT: maybe the 32bit x86 libraries/packages needed by the UT binary need also to be installed. I'm not familiar with box86, but in this kind of cases maybe you need to add a new arch to dpkg in order to be able to install the dependencies. Is the binary even working on a (modern) PC Linux installation ?

@mitu
ut2004-bin runs fine on my Twister OS on the same Pi4. There is an older version of box86 :

Box86 with Dynarec v0.2.1 aa7b620d built on Apr 7 2021 17:38:04

But I don't know how to install the same version on my Retropie.

Edit :

v0.2.1 is missing in the releases lol

https://github.com/ptitSeb/box86/releases

I will try to build some others versions tomorrow.

Nash

@mitu It's working perfectly with box86-0.2.2.

Here is my script that runs UT2004 natively at full speed on Piboy XRS through EmulationStation with mapped controls. We must go into the UT System folder before launching ut2004.bin to avoid "MissingIni" error.

if pgrep xboxdrv; then sudo killall -s SIGKILL xboxdrv > /dev/null; fi
cd
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
--detach-kernel-driver \
--config /home/pi/RetroPie/roms/ports/PiboyXRS_unreal_xboxdrv.cfg > /dev/null \
&
cd
cd '/home/pi/RetroPie/roms/ports/UT2004/System/'
xinit /home/pi/box86-0.2.2/build/box86 'ut2004-bin' > /dev/null 2>&1 
sleep 1

sudo killall -s SIGKILL xboxdrv > /dev/null

The PiboyXRS_unreal_xboxdrv.cfg file :
(Should be working with any gamepad with adjustments)

You can adjust some keys in UT controls parameters in game instead modify this .cfg that can be used for ohters FPS games.

Thanks for your help.
