I have finished super wonderboy in monsterland yesterday on an opk version of dingux-SMS, as I know really well this game here's what can be ameliorated on Dingux-sms
needs a V-sync
the music is laggy
the strech modes looks very bad (everything is deformed and everytime there's movement you can see the pixels stretching^^)
need to run at 60 fps wich is clearly not the case today.
But for all the rest it works good, it just need optimisation
