Play in 999 more than 3 hours. No freezes or graphic gliches. What I use: M3iZero 999 rom by RobotKillers + this AP fix (Thanks to herooftimedark!) Just put all files in one folder and run 999.bat. You get 999-fix.nds. Works flawlessly! Also there is issue with fonts, when using latest YSM3. Hope, that helps someone. Sorry for my engrish.
