Odd chips

hi, just opened up my games to give them a clean and i am now a bit worried that my kof games are boots, i noticed my 3 other games all have toshiba roms, the kof games have some roms that have exposed cores and some of them are just no-name roms.... they do look machine soldered though :/

EDIT:
ok saw in another post that you said that some other carts were legit (and they had the visible core thingy :P) so im guessing thats not a prob... then it just leaves me to wonder about the "noname" chips :/

if you post a piccy you will get confirmation one way or the other
