Is it possible to modify the screen of a GBA SP to SP+?

    Does anyone know if there's any hardware/software difference the GBA SP and SP+ besides the screen. I'm wondering if I can just replace the old screen with a backlit screen, or would I also need a firmware replacement? Thanks.

    They kept the ribbon the same and all the same button config so it should be as simple as drop in

    and while your at it may as well replace the shell the hinge is a pain in the ass to get apart so its best to start fresh

    Done! Now my SP looks better than ever. Thanks for the reply!

    The hinge on the SP is built really well and hard to take apart, but I didn't have to disassemble the hinge so it didn't matter. The ribbon cable... gah, that was a real pain inserting it back into the circuit board because it was so short and you can barely see what you're doing. Got it in after a couple tries.

    I found some interesting stuff when I took it apart, like how there's like a switch beside the game pak slot and it changes booting from GBA to GB/GBC. lol.

    That switch also changes the voltage from the GBA's 3.3 volts to the GB/GBC's 5 volts (it might be the other way around). A rumor states that Nintendo first tried to switch between GBA and GBC mode entirely in software (as evidenced by the fact that we can write to a specific address to crash the GBA into the GBC BIOS screen) but they couldn't get the voltage to switch over properly this way, so they had to use a hardware switch instead.

    Oh. Well that's a cool fact haha. Now I know why the DS can't play Game Boy games.

    Well, the reason for that is mostly because the Z80 processor that ran the GB/GBC is missing entirely on the DS. The GBA contained both its own ARM7 processor and the Z80 processor to run GB/GBC games, while the Game Boy Micro and DS have this second processor removed, probably to save space.

    Well, the DS is equipped with ARM9 and 3 processors isn't really necessary. Yeah, they're just make the DS bigger, more costly to make and people would have to pay more to get a feature they may never use. There are really nice GB emulators so it's not a real problem.

    I learned a lot about Nintendo handhelds by joining GBATemp and I have people like you to thank.

    I was being stupid today and decided to take that old frontlit screen apart. I got fingerprints and dust on the back of the frontlight and they just won't come off. Cleaning it only makes it worse and now the screen light is all "cloudy".

    I managed to find a really beat-up GBA SP+ when I was looking around at a flea market, the thing must have been tossed around.

    You'll just have to look around and hope you're lucky.

    You can tell the difference between frontlit and backlit by brightness. Also the frontlit screeen you can't see it very well from the side, the backlit screen has no problem if you look from the side.
