Keen goes Pi: Play Commander Keen mods on a Gameboy

[Nisaba]

Yep, there are tones of solutions out there for semi handheld devices. but I do love the fact that you can case mod an origin console from back in the day and tweak things to the limit.

What the fucl? 45% import fee. And I've always thought Denmark was member of the European Union?! What's wrong with you guys It would be even cheaper to get on a plain and pick up the package at Kites door...

About the soldering: YOU CANNOT DO ANYTHING WRONG! at least you cannot break or brick the circuit board itself. the board comes with JST-connection-wires which only need to be soldered to some extra buttons/a 3€ speaker. on the other side you simply plug it in. it's easy as that. skill level: rookie, I'd say.
If you wanna know how to solder eitherway the forums feature a beautiful step-by-step beginners guide called: Soldering School - AKA Don't wreck your new AIO board!

About the glue: it's only the screen bracket plus the on/off switch you'll have to glue in place. for everything else you'll use screws like you would assemble a regular un-modded case.
concerning the 3D prints: normally every town should have some kind of a "hacker-space" with 3D-Printing devices. but I could be wrong about that.

Getting to work now. Bips and bobs delivered in the mail. Case modifications coming along. Stay on target. Attempting to drill holes for X & Y buttons. Decided I do want L & R buttons. Must make holes for the status LEDs. Not sure how to proceed beyond this point. Must buy glue, tape and soldering tools.

The motherboard is a real beauty, isn't she?!

about the case mod: I'd recommend to not drill the x&y holes unless you have the screen bracket printed/bought. This is because you need to make sure to line things up. (Of course you can come up with your very own design ideas, but things are so much easier when using some given templates. At least when doing such things for the first time.)

You can use whatever tools you want, but here is my little recommendation list:

• 3D print your own screen bracket (or buy one over here: https://www.sudomod.com/forum/viewtopic.php?f=27&t=2553
  

• use a step drill for the x & y holes (~3$)
  

• when done things should look something like this:
  

After that point you are done with the hardest part and you can start assembling all pieces and bits. The wiki is always a good place to consult when having issues while assembling. https://github.com/kiteretro/Circuit-Sword/wiki

Thanks, Nisaba! I shall be flinging questions your way as I progress further.



My main trouble now is getting hold of the proper battery.

Was this Kite package supposed to come with a fan? Or was that an optional add-on?

[Nisaba]

Yeah, green buttons on a black build. I added black ones this time around but I think I'm gonna exchange them for bordeaux coloured buttons...

You could use nearly any smartphone battery as long as you can manage to fit it inside the case. Anyhow, I'd go with this battery over here which is the perfect solution for this project in terms of size and power: https://sudomod.com/forum/viewtopic.php ... 320#p24389 you might want to check the shipping conditions though...

The fan is optional and so is the volume wheel. I have added a fan but in my experience it's not really needed unless you are about to play a whole lot of PlayStation/Dreamcast games. The volume wheel on the other hand is a neat extra as it gives the GameBoy a more classic kind of look and feel. You can still purchase one of these until February the 27th. But remember that it's either the HDMI out or the volume wheel. Link: https://sudomod.com/forum/viewtopic.php?f=38&t=5212

I updated the first post with fresh information and a little how to guide. check it!

Thanks! I'll give it a read. This helped a lot in terms of putting it all together:
https://sudomod.com/forum/viewtopic.php?t=5268

I think I totally botched the back board, whatever it's called. The board with L1, L2, GND, R1, R2, GND. The power switch does fit nor does it respond properly. The gluing process didn't go so well either. The case doesn't fit together properly. But the first boot was a success! And my battery provides power, which means I soldered the wires correctly and got the voltage (minus/positive) right! I want to try some synthesizer DIY stuff, so maybe it's not a total loss, having all these new tools around.

[Nisaba]

yeah, that's a pretty decent picture based tutorial. seeing is believing...

IIRC there is an issue with the responses of the power switch, but that is due to the different production lines of those after market cases. when you close the case the switch feels a bit wobbly, right? what you wanna do is hot-glue it to the actual switch pin. this gives you the needed millimeter to power things on and off smoothly. just make sure to stick it to the inner right corner (when looking at it from the front case). and I'd recommend using hot glue since you can heat it up later on, if things got messed up.

what's with the backboard L1-R2? does it fit in place?
what about the rest. you spoke about tight-fitting things in order to close the case. but "normally" you should have enough room for every bits and pieces. if you post some pics I can guide you along the process. I did a lot of mistakes in my previous builds and feel real confident by now. so I might know some dirty tricks to fix things...

don't give up just yet. I can promises you, it feels real good when finally everything comes together. and building such thing gets quite addicting after some time. also my soldering skill level evolved rapidly, which is a nice side effect.
