I haven't kept up with this thread 100%, only peeked in every so often. I've only noticed talk about games, but haven't seen any talk about hardware. So...
Just showing off my collection.
The brick is my original GB from (I'm guessing) 93 or 94. I got the Tetris bundle, like most people. It still works, it just needs a little TLC. I never intend to use a non-lit screen ever again so I don't know if I'll ever get around to fixing it up. I was thinking about doing a back light mod to it, but I don't know since...
I just got a GB Boy Colour. This thing is surprisingly awesome for a Chinese clone console! I know the screen stretches the image, but it's only slightly. Not nearly as drastic as stretching 4:3 to 16:9, I hardly notice with most games. The viewing angles aren't as great as real Nintendo handhelds, but it's not bad. Outside of that, the screen looks amazing. And surprisingly all the buttons feel great, even the D-Pad. And they cloned the hardware close enough that my Everdrive GB works perfectly.
The Indigo GBA has an AGS-101 screen in it. I'm considering putting one in the translucent GBA as well (it has the stock screen still) since the AGS-101 screens are plentiful right now, but they're not cheap.
I don't know how I ended up with four SP's. They're all front lit, which I don't mind so much, but I've been thinking about getting a back lit SP. I kind of want to keep them all because I love all the colors, but realistically I'm gonna part with two of them (or 3 if I get a back lit SP). I just can't decide which colors to keep!
Not pictured...
I have a translucent purple GBC that I don't know where I got it from. Probably a thrift store. It needs some minor repairs (easy fixes) but I never get around to it because of the unlit screen. Back light mods are impossible, but front light mods exist. But I'm not sure why I would want to front light mod it when I have a back lit GBA and GB Boy Colour. So, it just sits in the pile of stuff I need to fix/refurbish one day.
I have a first gen DS but it doesn't get much use. If I'm gonna play a DS game, I'll usually do it on my 3DS XL. And I don't like using a DS for GBA gaming because of the awkward A and B button placement. It's very uncomfortable in my opinion.
