Could someone tell me why memcpy and DMA 3 transfer should result in different processor behaviors, other than speed? When I replace my DMA copies with memcpy...
Maybe you could get away with just changing the height and width fields for the bitmap header data before you load it into the editor. If you set the width to...
I've got problem with SWI 2. I want my program to wait for vblank in energy-efficent way. I've set up interrupts: *((function**)0x03007FFC) = handler; ...

Well, I don't have an answer for you, but I did notice that the tile data for BG1 overlaps with the map data when you switch it to the first tile block - just...
Thanks for the reply, though this app doesn't currently have the functionality I'm after. I'm looking for something that doesn't require a char set/tile set to...
... I dont understand it fully either, perhaps that is right. I just thought the screen is 'dark' by default which implies it needs power to make it light. Tom...

In a SNES->GBA conversion we're doing, I need to rearrange the data in a bunch of 32 x 32 character (pointer) maps, but to keep the original game's character...
... You can do the following to draw less power: * turn sound off (cuts off power to the audio circuitry) * turn off ROM prefetch (reduces power to the game...
... Maybe I'm being dense. Wouldn't it be darker colors which would draw extra, since LCD draws power to become opaque, and thus to prevent reflection? I...
games run synchronized to LCD refresh and usually require less time for processing one frame than available (1/60 sec.) you can halt the CPU until screen...
Hi, As far as I know every action the GBA does costs battery-power. The screen, sound, processor etc all take a small part, and if you look closely you'll see...
... There are two power saving modes which can be enacted by BIOS calls: stop and halt. Stop turns pretty much everything off; halt turns off the CPU. Both...
... Having 'louder' (including many frequencies simultaneously) sound will increase battery usage. Heavy CPU usage will also do this. Possibly even brighter...
