MastermindDS - Update! v1.20

Gusec has updated Mastermind his game for the DS, heres the full release info:

It's Mastermind, a codebreaking boardgame!

I've finally completed my first game to the DS, with PAlib.
It may still host a bug or two, so report if you find any!

Rules
The rules are simple;
You should in eight attempts , try to guess the order and colour of four marbles, to your help you get stars each turn.
Silver tells you that one of your marbles has the right colour but not the right position,
and gold tells you that one of your marbles both has the right colour and the right place.
It's up to you to find the right code with the hints you get!

Information about this version
I've tried to make it as stable as possible, though it's my first attempt!
I'm going to improve the flow of the game, and maybe add a couple of functions, like a better HighScore-list or some unlockables.
This is still an early version. So if you find anything weird, please let me know and I'll try and fix it!
Secrets are none so far, besides one little easter egg that may occur if you lose...
It contains three different levels of difficulty, from easy to almost impossible, so it should contain enough challenge.
Level-setting reachable via Start, and HighScore-list (new game here to), Select.
* 1.02 - Fixed memory flaws and slow graphics.
* 1.03 - Improved sprite management. Version number added to description.
* 1.20 - Fixed, brighter graphics, faster flow. Highscorelist added!
