How to bypass Health/Safety w/o flashme
Some flashcards already automatically bypass the health/safety warning, but some don't auto-boot(AK2, RPG, Cyclo(iirc?)) .
My AKRPG does not, and it bugged me. But flashing seemed a little extreme (and pointless nowadays) to me.
Anyhow, I came across this method by fellow GBAtemper
FatD on how to soft-flash your DS.
1.On your DS, configure all settings not done on initial startup (GBA screen, Auto-boot (MUST BE ON), region etc.).
2.Remove your battery for about 15-20 seconds to clear volatile data.
3.Replace battery and go through initial setup, but when it prompts you to press A to turn it off,
use the power switch instead.
4.Insert your flashcard and boot 'er up.
You will lose access to pictochat and download play until you complete initial setup (undoing this softmod), though.
The process is fully reversible by booting into the firmware menu and redoing the settings.
