goldstar.cpp: decrypted chryangl and chryangla (nw)

Browse Source 
chryangl gets in game but gets stuck when betting or after some time in attract mode; chryangla shows a black screen but can enter various test screens. I'm decently confident these aren't decryption issues but maybe extra protection
