Could someone please share with us the following information about
GBA. At the very least I would really like to know the top 3.
Thanks.


1. How much Ram the GBA has (compared to the 32k the GBC has)?

2. How many Sprites the GBA can display (compared to the GBC 40)?

3. What sprite modes are available (i.e. 8x8, 8x16, 16x16, ...)?

4. The Attributes Setup (i.e. what is in it, how many bytes each
sprite takes up)?

5. How tiles are stored in memory (i.e. like GBC, but with 4 planes
instead of 2)?

6. The number of "Backgrounds" or "layers" the GBA has (compared to
the background and window the GBC has, and anything fancy about them)?

7. If any special tile modes exist (i.e. 16x16 tiles in the
background
instead of the normal 8x8 or such)?

8. How the Palettes are set up (i.e. how you load them, is it like
the
GBC with 2 registers you work with)?

9. Anything else really cool (such as the priority bit of the
attributes on the GBC, If individual sprites can have an Alpha
Channel
applyed to them, If Sprites can be rotated or scalled, etc...)?

... strange as ... Alrighty. Are you guys sure the 256k is on the Cart? Or is it a possibility that 32k is like a CPU cache or just High RAM and the 256k is...
