Well I have MAMEWAH and all but how do I get GAMES?!?!?! Do I use other emulators like Nesticle and modify the ini file???
How much have you actually used emulators / front ends? From this comment it sounds like you have limited experience. I think that's why brophog responded the way he did.
There are at least 3 pieces to the equation
1. An emulator
2. ROM(s)
3. Front End
There are several emulators out there MAME being the most well known and capable.
ROMS are a touchy subject... which should be avoided in this forum... you will have to read and understand the legalities of using them for yourself.
Front Ends... Mamewah is an EXCELLENT front end but does require some research and patience... many of the same Mamewah questions get asked over and over again... "how do I generate lists..." "how come I cant see my roms...." "how do I do custom layouts..." yada yada yada... Mamewah is my favorite front end... but there are several others out there you may want to try first if you don't feel up to the research...
Please forgive me if I sound condescending... that is not my intent... I just want to figure out where you are technically...
Have Fun
