Fastest way to update linear screenbuffer.   Message List  
Reply | Forward Message #1254 of 15019 |
Multiplayer without more carts

Hi,

Just read somewhere that MarioKart Advance will feature a 4 player mode
without the need for more than one cart (pocket.ign.com today)

I'm not 100% familiar with the specifics of the GBA, but I do know we used a
lot of DMA-streaming of tiles in our GBC game.. I also gather that you won't
be able to do this via the cable for 3 other GBA's. So does this mean that
the mulitplayer mode of MarioKart Advance doesn't use streaming of
graphical/sound data?

Greetz,

Collin van Ginkel
