To: submit@mamedev.org


Hi

This is the finished work for megadrvb.c:
Merge ssgbl into megadrvb
Moved inputs game from megadriv.c to megadrvb.c
if you use R2 diff i change also the roms names for a better fit the
drive in ending with "mdb" wich means "mega drive bootleg" so the
result is:
aladbl     -> aladmdb
mk3ghw -> mk3mdb
ssf2ghw  -> ssf2mdb
ssgbl       -> srmdb

The R2 diff is the better way but you choose the best for you.

Bye Sonikos
