Need clear vram on startup about devkitsms HOT 3 CLOSED

Hello!
Yes, VRAM doesn't get cleared on startup for the simple reason that it's useless to do it.
When the library startup code is completed, screen is left turned off. So that's when you can load the tiles you need and load/generate the tilemap in VRAM, and also load/set the palette(s) you need, and after that you can turn on the screen.

Also I forgot to mention that should you anyway for any reason need to write zeroes to VRAM, there's the handy function
SMS_VRAMmemset (unsigned int dst, unsigned char value, unsigned int size);
so for instance you could clear the whole VRAM using
SMS_VRAMmemset (0x0000, 0x00, 16384);
(0x0000 is the VRAM start address, 0x00 is the zero byte you want to write all over and 16384 is how many bytes you want to write)
As said this is likely going to be useless anyway ;)
