dont listen to anyone. Nothing on a computer is impossible provide you have the drive to make it happen. Lucky for you this is so simple.
install virtual box. then install the windows 98 iso file in Vbox(if you have issues with this im sure there are instructionals online, but you should have no issues). then use your legally purchased product key(and not just a product key that someone posted in a forum found off of google.)
only allocate 512mb Ram to the virtual machine or you will get errors that says "insufficient memory" 512mb worked great.
FYI windows 98 has no firewall or antivirus. so learn about the network setting in Vbox, and maybe isolate your laptop on a vlan. but you can also get the game you want and place them in a share folder with your virtual machine. then you never need to allow windows 98 to touch the internet.
