Well I think that might just be the case! lol
Actually, the SRA is better than the GPB in most aspects. The video quality, the sound clarity, the way the games fill an entire 4:3 CRT screen without being windowed, or fill a 16:9 HDTV with only a hint of a black border. The clone is great, playing games just like the real hardware to the point you'd never know it's a clone.
The biggest problem with the SRA is lack of GB and GBC support. It still means if you want to play GBC games on a tv without emulation you need a GBP. But for all things GBA, this is my adapter of choice.
