Oh nooo, I'm sorry. D: Yeah, Emulation is a very busy section so sometimes the mods miss things or can't catch issues right away. I recommend asking in either the
Emulation Simple Questions or
ROM Hacking Simple Questions thread depending on what you want to ask about. Emulation is for emulating games in general, while ROM hacking is for questions regarding to hacks. But either way, welcome to PC!
I don't believe there are any places here where you can see 100% completed hacks. The Hacks Showcase subforum is as close as you'll get; all of the high-quality hacks are housed there. There used to be a thread managed by a member that listed all completed hacks, but it hasn't been updated for a year and a half now and was locked. Honestly, your best bet is probably just to look through said thread or check out the Hacks Showcase. :( Good luck! From what I remember, it has been suggested before to have a place for completed hacks, but I don't fully remember what happened with that idea.
Hope you have a good time on PC though, and you can always private message me if you need further help. I'll get back to you ASAP, so no worries! May not be the best when it comes to hacks but I do know the ins-and-outs of the section so I'd be more than happy to assist. Would be the better choice since your intro's for welcoming you to the forum. ^^
