@dragu The crash at boot is only because of the presence of a *.pc folder into another subfolder (instead of plain /recalbox/share/roms/dos) it doesn't crash as soon as i remove the *.pc folder from the subfolder and leave it at /recalbox/share/roms/dos

Now with original dosbox.conf file of the game, even without the autoexec part, yes it crashes and I had to use your file (the lba one you gave me a while ago wihtout the autoexec part off course), i don't know why but comparing them there are several differences
yours : https://pastebin.com/NFM7uX51
mine : https://pastebin.com/2sGm8u6X

at least output=overlay instead of texture raises a warning in dosbox when launched from command line

"And CD Wacky ? Should it not be CD Wacky.pc ?"
No because when in dosbox.bat . is already setted into the game folder, just like πŸ˜„ , here WackyWhe.pc
so imgmount d .\cd\wackywheels.iso -t cdrom directly mount the iso located there /recalbox/share/roms/dos/WackyWe.pc/cd/wackywheels.iso
And there is a message regarding the mounting at the beginning (after the dosbox orange green) which show that the path is indeed the good one like "Mounted d on /recalbox/share/roms/dos/WackyWe.pc/cd/wackywheels.iso"
and cd WACKY goes from /recalbox/share/roms/dos/WackyWe.pc to /recalbox/share/roms/dos/WackyWe.pc/WACKY folder where ww.exe is located
at the root of my game folder i only have the cfg file and the bat file

Now for ratio comparison we can clearly see the difference especially on the Apogee Moon in the logo which is clearly not round but elliptic on Recalbox : (up real 4/3 dosbox on windows, down something between 4/3 and 16/9 dosbox on recalbox)

This is again with your dosbox.cfg (but i have a same result on another game without any dosbox.cfg in game folder), the vertical black bars on both side should be twice as wide

OK your file had just aspect=false with aspect=true I get the correct 4/3
I assumed you got your file from the dosbox root folder and this is more or less the one used by default so this might be a bug for 4.1
