I dont know if it is useful, but for the sake of completeness, I have reversed the hash algorithms for debug NPD headers. Interestingly, the devklic can be retreived from debug files which are not type=1 (most EDATs are not type=1, only USRDIR/EBOOT.BIN are type=1).

Pseudocode:

function byte[] nameHash(byte[] digest) {
	byte[] nameHash=new byte[16];
	for (int i = 0; i < 16; i++)
		nameHash[i] = digest[i] ^ 0xFF;
	return nameHash;
}

function byte[] headerHash(byte[] digest, int type, byte[] devklic){
	byte[] headerHash;
	if (type == 1){
		headerHash={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1};
	}else{
		headerHash=devklic;
	}
	for (int i = 0; i < 16; i++)
		headerHash[i] = headerHash[i] ^ digest[i] ^ 0x55;
	return headerHash;	
}
