Started building up my own cabinet (a youth dream) with MameWah..
Then, being an IT professional, together with a friend, I moved to designing and developing my own FE to have something nearer to our needs.
When I found it mature and (hopefully) consistent, I published it, and started implementing others' needs.
Now I almost only develop: my cab's room has become my little daughter's bedroom (sigh :-) ), and my "beast" is switched on almost only to receive last FEEL updates.. When I can :-)
But even if I play very rarely, I always "need" to have my oldie-goldies with me.. So I have setup emus on almost anything: PC, smartphones, raspi, old consoles.. Anything capable to run them which comes handy.
In these days I'm on holidays, so I am playing around with the oldest PS2 I left years ago in our mountains flat :-)
