Having located a copy of this game on Rapidshare, downloaded it and un-RARed it I am now stuck...

I have a 3+Gbfile called Oppai2 that styles itself an ISO Image file.

I have tried burning it to a DVD but no success.

I would be grateful for any assistance here....

Try using Daemon Tools or similar for mounting the iso on a virtual DVD...
Good luck!

Yes, I have used Daemon Tools for Oppai slider. I am sure there are English menus, etc. available too. I didn't like the game much. Artificial Girl is much better.
