The perfect GameBoy – The Sequel

Every time I decide what the perfect Game Boy is, something happens and I reconsider. The same can be said for many retro systems, because there seems to be an endless stream of hacks, addons and mods for almost anything from the 80s, 90s and 00s nowadays.

Previously (see here), I had considered the GBA SP 101 with a new shell and fixed shoulder buttons to be the perfect Game Boy, since I love the form factor and the screen was lights ahead the GBA SP 001 and of course the original GBA non lit screen. Since then, I modded the original GBA with a very nice backlit screen that improved things dramatically and made it very playable in all lighting conditions, on par with the SP 101.

Now, it’s time to take my SP 001 and take it to another level by installing the best screen on the market, the Funnyplay v2 IPS Laminated display.

This display is hands down the best one yet. IPS colors, 5 brighness levels (and it gets REALLY bright on the highest one), 4x the pixels of the GBA resolution, resulting in no distance between pixels, very fluid (no tearing like previous Funnyplay displays), infinite viewing angles and the display is laminated to the glass, so no dust between the glass and the screen ever and the screen seems to pop. Oh, and the price is very competitive compared to backlit aftermarket displays.

I am really struggling to find anything bad about this mod, but if I had to I would say that it may use a bit more battery. And that’s about it.

The display came in a nice orange box that kept everything safe. In there you will find the display itself, a ribbon cable with a small circuit board and a very thin wire. Oh, and a square white foam that you have to put behind the screen.

If you plug the display on the ribbon cable and plug the ribbon cable where the old SP 001 (or SP 101, works there too) display was, it just works. So if you don’t care about the different brightness levels, you are done.

I modded my only SP 001.

Modding was relatively easy. The hardest parts was trimming the back cover of the display to allow it to fit and soldering the thin cable to enable the brightess button to switch between the 5 brightess levels.

You have to trim only one side as shown below, and don’t forget to put the foam behind the screen before closing.

For the easy soldering part, which you should do after you pass place the display, connect the ribbon cable and pass it through the opening, the thin cable must be soldered on:

a) the solder point on the ribbon cable itself, as shown here:

b) the solder point marked Q12B on the motherboard of the SP, as shown here:

This is it. Close everything up and you are good to go.

Now all my GBAs have backlit screens. Funnily enough, the original 101 screen is the worst of them now , with the aftermarket backlit taking second place and of course the new Funnyplay IPS taking first place

Here are some close ups of the 3 screens. See if you can spot the new IPS (hint: it has 4x the number of pixels, so it’s super sharp compared to the others with no visible gaps between the pixels).

Micro Gotek replacement on my Amiga 1200

I’ve recently replaced my Gotek which I described in previous posts (http://www.karios.gr/?p=1029 and http://www.karios.gr/?p=1003) with a Micro Gotek (found here: https://www.sellmyretro.com/offer/details/32413). As a reminder, the Gotek and Micro Gotek are floppy emulators that replae the old-school floppy driver on the Amiga and can read and write on virtual floppies stored on USB sticks (called adf files).

The main difference between the two is the size that takes inside the case and convenience with the cabling. In the old Gotek, I needed to solder wires on the switches for example while the Micro has everything on normal headers, for buttons or a rotary encoder. I chose the latter, which is much more convenient for scrolling through lots of ADFs while still using the encoder as a button to load or eject virtual discs. Another big difference is that you can connect the USB outside of the case, which is very convenient if you want to change USB sticks often.

I chose the Micro Gotek version that goes directly on the motherboard to avoid using a floppy cable and the need for yet another 3d printed base to base the Micro Gotek on. I also printed a new version of the control box to accommodate the USB and the encoder. I shared the file here:

This is a work in progress and I do already regret putting the USB and encoder on the same place, which I plan to change in later versions. If you push them enough though, they will fit.

I also printed the encoder cap found here:

Having the Micro Gotek directly on the floppy connector on the motherboard also leaves few choices for getting the cable outside of the case of the A1200. One would be through the ventilation grills and another from the back side (e.g. the expansion port), using cable extensions.

The Micro Gotek uses the same FlashFloppy firmware which I used for my original Gotek and it updates just fine (I have it updated to version 1.0, which is the latest at the time of this writing, with no problems). It also works great.

The final result looks like this:

The perfect GameBoy

I just finished restoring the perfect GameBoy, in my opinion, to the perfect state! But first a little history:

First was the original GameBoy which took the world by storm by being an awesome way to play video games on the go, with the important feature of actually being able to play different games on the same portable console, a new thing at the time. Technical wise, it was not anything spectacular to speak of, it featured a few grey (well, more like puke-green) colors on the screen, which was not even lit, so no playing in the dark for you (at least without any of the numerous silly light-and-magnifying glass after market add-ons). But it was more than good enough, there were some awesome games on it and the 4 AA batteries last for a long time. 

Then we had the GameBoy Pocket, which was the same thing but smaller and only took 2 AA batteries. Other than that, it was the same machine.

Then we had the GameBoy Color. This could play all the original GameBoy games with the option to turn their grey palettes to a color palette with the same number of colors but at least there are colors. There were also games built specifically for it with better colors. But other than that, the screen remained non-lit and the quality of the games was more or less the same as the original.

Here I should mention that in Japan only there was a special version with a lit screen, called the GameBoy Light which was essentially the Pocket with a front lit screen. This never came out anywhere else.

But then we had the GameBoy Advance. Now this was the real deal. The GBA was more or less on-par with the Super Nintendo, power wise and it fit in your pocket. The future was there! It was also backward compatible with original and color GameBoy games, so at launch its software library was already huge. 

The original GameBoy Advance featured the controls on the sides of the color (but STILL not lit) screen and took 2 AA batteries for power.

The next version was the GameBoy Advance SP. Hardware wise it was a GameBoy Advance, so all of the same games played fine (including original GB and GBC games), but it now featured a much more pocket-able clam shell design. And the screen was lit for the first time!

There were two versions of the SP though, the original SP model 001 featured a rather unimpressive front lit screen that looks, well, not so good, but you could play in the dark for the first time and that was important. But the second version was the real deal. Model 101 featured a very bright and beautiful backlit which is on-par with the ones found on the DS which came after that. These are quite rare and expensive to find nowadays, but in my opinion they are the best GameBoys ever made, since they are backward compatible with ALL GameBoy games ever made (GB, GBC, GBA), they have an awesome small foot print clam shell design and they feature the best screen.

The last GameBoy SP released was the SP Micro, which was a super tiny version of the SP and played only GBA games. These are very nice, feature a smaller backlit display but they are a feature less than the SP 101. 

So, since I never had a GBA, I decided to go hunting for the perfect GameBoy. Finding a 101 was not too hard, the price was a bit high though and, since it’s now more than 15 years since it was released, there are always some problems with them.

The most common problem is of course, the state of the plastic chassis of the device. These games were meant to be carried around and played, so scratches and filth was everywhere. Repairing and cleaning was out of the question but thankfully, you can buy a replacement beautiful brand new plastic chassis for less than $10 online, which is exactly what I did.

The second most common problem is the shoulder buttons, which wear out and stop working after a while. On the device I received, both shoulder buttons were not working at all, or worked when they felt like it. Here, I had to open the device and desolder them, order new ones online and replace them and boy did this make a difference. The new shoulder micro switches work perfectly and they also have a very satisfying clicky feel to them, not present in the originals.

Lastly, the battery needed to be replaced, just so it can last for a good few hours more of gameplay. You can also get them brand new online very cheaply.

So there you have it, I am now a happy owner the of the perfect GameBoy!

Update:

Another one, this time a 001 model, is saved and added to the collection. New shell, new shoulder button microswitches, like new!

Welcome!

Update 2:

Another GameBoy Advance joins the collection. This time it’s not an SP but a regular GBA, but with a brand new plastic hell, screen crystal and backlit screen modded. This was a relatively easy mod, there are lots of tutorials on how to change the original non-lit screen to an after market backlit one (e.g. https://www.instructables.com/id/Gameboy-Advance-Backlight-LCD-Screen/).

The only things you need to be careful is the screen connector model you have on the GBA motherboard (40 pin or 32 pin – determined by the first number you see through the battery compartment – 0 for 40 pin or 1 for 32 pin. They are also called type A and type B) and to careful to solder the screen power wire correctly on the GBA motherboard to get power for the backlit screen. Other than that, it looks and plays awesome:)

Welcome old GBA with brand new screen
My GBA collection so far.
