So you're probably wondering, what is a GBA-2 Go. Well good question, I hope you can already guess GBA stands for GameBoy Advance. The 2 stands for second version, doesn't really have a meaning. and Go because it's a handheld and you can take it on the Go. get it? on the Go? nevermind..
Anyway, so you're reading this and you're wondering what this project is about. Well first let me warn you, I'm just a student and electronics enthusiast. So don't go getting your hopes up.
Let me get back to business, the GBA-2 Go. Mainly it's just an custom GBA PCB but with as many mods integrated as possible. Mod list will be near the end.
You went to look for the list didn't you, well not much has happened since you were gone. Lets continue, I started doing this project to learn more about electronics. Because what teaches better then learning from your own mistakes, especially if it costed you an arm and leg to build it.
Now you're wondering, that sounds great and all. But how did you emulate the AGB-CPU? Well to be honest. I didn't, I'm a hardware engineer not a software programmer. I just used the original CPU and SRAM. I decided to harvest the SRAM because a new one would be close to €10 a piece. And yeah, you already have to sacrifice a GBA when you want to make it.
- Variable clock
- Tact switches
- Button backlight
- Multiple improvements: LiPo battery charger, new power button, USB, audio amp and possibility for 32 and 34 pin screens(GBA and GBA SP)+backlight control for the GBA SP and IPS kit ~Not in the trimmed version.
- UDLR can also be swapped with an Joystick if you're not happy about it. ~Not in the trimmed version
- Digital volume control
The trimmed version was brought to life to get an actual working prototype, instead of smacking together so much stuff you cant test properly. But mainly just to save time, I mean.. time is money..
It all is being controlled by an AtMega32u4
If that doesn't impress you, then come with another mod that I could add to the list or to the GBA-3 (/DMGBA)
About GBA-2 Go, I named it Plus Ultra because.. yeah I am pushing the limit, kind off. But okey, GBA-2 Go Plus Ultra does sound nice
