Most "bugs" on the M3/G6 and even R4 are caused by the "Soft Reset" feature. If you leave it OFF, 100% of the games will run flawlessly. About 95% of the games will run with the Soft Reset feature. TWEWY is one that is buggy with it on. When you have to press select for a battle to start (begining of each week), it will glitch and WhiteScreenOfDeath if you have the Soft Reset.
For those of you who don't know what the Soft Reset feature is, if you hold LeftRightYAB or LeftRightXAB it will take you back to the Firmware menu to select a ROM... you don't really need the feature, just turn off/on your DS and it'll do about the same thing... just takes 2-3 seconds longer.
