Bulovitz: it's working for me. I use eXtragry.pl version. Copy everythink from dos game folder to ./Olympic Challenge/SUMMER in gog galaxy games folder and change ./Olympic Challenge/dosbox_games_single.conf file with notepad line from
:summer
cd summer
cls
summer.exe
goto exit
to
:summer
cd summer
cls
s.bat
goto exit
Game start from shortcut or from gog galaxy but when you start game first enter the setup and back without changes.
I am Polish and I was talk with support workers about this. They are gives me stupid advices non helping with anything. I am shame the gog is related with cd project red from my country. GOG support sucks. Zwykłe tumany, które przy każdym problemie zostawiają Mnie samego z poszukiwaniem rozwiązania problemu. Żeby was skarbówka i Uokik zgnębiły.
I actually sent another support ticket referring to this game / thread when I made my previous post on 9th June. I haven't had any response to this support ticket to this date. To say I'm highly disappointed in GOG is a massive understatement.
You may have found a solution to fix this issue but at the end of the day, the issue shouldn't be there in the first place and we should not be the ones to have to work around issues they created.
I love GOG for the old games and DRM free approach, but if they refuse / can't fix a clear and obvious issue with their release, then I am less likely to recommend them to anyone else.
