I am new to the whole arcade world,  but I am building a 2-player arcade with 8 buttons for each player.  
Not completely sure what the best button scheme is,  but it seems the common button layouts have the following button/letters:   Y, X, L, B, A, R, Start, Select ?   
Do you offer a set with simple black letters.   If so,  I am interested to order 2 sets.
Thank you!
