Q: Are there any hardware differences?
A: The GBA SP has exactly the same technical specifications as the GBA.
The packaging and form factor are different, as well as the LCD screen
and batteries. There are no hidden registers nor new coprocessors, nor
extra buttons. From a developer's point of view, the SP is the same as
the GBA.
So now that Nintendo has announced the GBA SP, and thus making the rumor of the GBA + come true, what about the CPU upgrade? Haven't seen anything supporting...

Am I the only one that's worried about how uncomfortable it looks like it'll be to play. the bit you hold is pretty much square and the d-pad and a/b buttons...
I heard that the flash cards won't be working on the SP. I don't know how much of this is true, but maybe someone else can confirm this ? ... Van: Aaron...

... If that's actually true, then how will a publisher be able to QA test games on the SP? -- Damian p.s. the SP should have had select and start next to B and...
... Without wanting to stray too far off topic, I doubt that Nintendo are concerned about publishers using flash cards, they probably worry more about the...
Theoretically the only real change needed would be to add some kind of hardware test that wrote to a ROM address with a known value and then read back the...
Any system that you came up with would be patched out within the first week of it's release -- if not sooner. The problem is that the code you are trying to...
I don't entirely agree. I know plenty of game pirates (despite my attempts to turn them). And if they really want a game, and it's taking too long to crack,...
Just figured I'd point out that doing this would defeat most legitimate usage (3rd party devel who want their games to run on GBA & SP) and limit Flash Advance...
Where did you hear that one from? A rom is a rom, is a rom! They'd have to start making new roms, with a key section, or something similiar, to block out a...

Where did you get the specs from? I remember reading that the GBA + (GBA SP) would get a hardware upgrade (possibly) but I really thought that was a rumor....

Hi I have written stuff to display hardware sprites in MODE 2 fine, however I have read that you can display hardware sprites in MODE 4 aswell (with less space...
I've not looked at the source yet but I would suggest checking that you are only using characters 512-1023 in the OAM ram as the first 0-511 characters are not...
Ditto to previous reply. Plus the mistake I made when I was trying this was when I was working out the memory offsets for the correct address of character...
I've looked in the source quickly. It's probably because in mode 4 there's only half the memory for the object char data. And this half is in the higher...

I have tried setting the charname to 512 (ie the setting of attribute2); but it still does it. I also tried changing the OAM position 512 onto what it is now,...
You also have to put your sprite data in the right memory adress !!!! In : for(index = 0; index < 256*8; index++) { OAMData[index] = sprite1Data[index]; }//end...

... The right address would be 0x2000, not 0x4000. In combination with a 'char_number' of 512 this does actually make your little sprite program work correctly...

damn c programmers :) frame buffer size is 0xa000 double buffered = 0x14000 this is the start of sprite memory that is usable. so the actual vram address is...
