That's awfully close to asking for a crack. ;p

Such topics are not particularly well tolerated here. The admins here are pretty strict on respecting copyrights and use restriction measures.

I don't know but does the game track the time played in a file or registry? Or if you could turn back the Windows time clock?

Oh i didn't intend to crack It, i'm just curious yo study it..well i wish also to see if with that time limit you could be able to reach demo limits or not..however i hate those countdown demo, i mean i prefer shorter content, but relaxing, rather these anxiety trigger things 😂

Need some kind of tool that looks in ram and find the place in ram where the countdown is stored and then maybe you can lock it. I think Cheat Engine does this but I have no idea if this is available for windows 98 but there is likely an equivalent.

You might want to look into the functions SetTimer, KillTimer and the WM_TIMER message. That would be one way to implement it.
