Hey there and welcome to PC!
I'm glad you found your passion for Hacks again, and there is definitely a lot of them around here, so make sure to try out a few!
About your questions, It would be best if you posted them *here*, which is dedicated to Questions about Emulation. This way, you can be sure someone who actually knows a solution is going to help you out
If you need anything else, contact a Mod, they always help out and are very nice people.
Other than Hacks, PC has a lot of stuff to offer, so make sure you explore every forum :D
Glad to have you with us, and again, welcome to pc!!
