For newbies who want to play this game, is there an installation instruction? I downloaded everything but I do not know what to do next. thanks
Yes. In the readme.
But if you need it simplified.
1. Download the original Chinese FF7 ROM (Google the filename, is all we can say)
2. Download LunarIPS
3. Run it once and close to it associate it with IPS files
4. Double-click "Final Fantasy VII Advent Children (Finished Version).ips"
5. Find the FF7 ROM and click it.
