For anyone wishing a bit of the same. Just download GPM2 from Abandonware (even though I still have the original - no CD player on this laptop..!), download the Wing32.dll on this board and copy it into either System32 or SysWOW64 of your C:\Windows folder (I did both to save time).
Both GPM and GPM2 are still perfectly crafted F1 management games in my eyes even 25 years later on. Grand Prix World was also fantastic but something about these two games keeps me coming back.
Great to see a community still alive for this game - good stuff guys!
