Oh yeah man Metal Slug 5 runing at 100%!!! The rom its correct even the P1 of 8M crc 3f1cf3d2, and without pacht or Ips or anything you only have to get the a new version of Mame but this one its special its seems to be made only to run the rom set of Metal Slug 5 One friend from my contacts of msn gave 2 files: mame_for_ms5[1].part1.rar 405k mame_for_ms5[1].part2.rar 447k when you open the files there are inside this Folder=CFG Folder=memcard Folder=nvram Folder=roms File=ms5mame.bat File=ms5mame.exe Then put the rom of mslug5nd.zip in the folder and double click in the bat file and the game begins exactly like the original of arcades Its really Cool Man thanks for all the people that made this possible.
