Hacking titles.txt and parental control

[Bosk666]

Hi,
i want to use the parentcontrol option.

here is the structure of my titles.txt
all gameid are taken from the gbatemp titles wiki

for kids:
gameid = name of game = number from 0-3

for adult:
gameid = name of game


result:

all games are shown -> no control .

then i changed this:
for adult
gameid = name of game = 5

now it works , but why. is there an error ? i red in an sample config.txt that mature titles need no rating ?
