I have nearly modded and upgraded all the main Game Boys. I don't want to do a Micro, and I just have a DMG left to do. For that I'll be using a Retromodding Neptune, and I cannot wait. It looks amazing.
I've never played an SP before. It's a surprisingly nice size and shape for my hands. I don't think I prefer it to the AGB but I definitely prefer it to the Micro. I just love handhelds. Any handheld.
