Since I'm not sure if i am allowed to post links to my website here, I'm posting it simply here. I decided to write this How-To... or... well... whatever this is *ugh*, because I searched the net all day and nite long (for two weeks? ._.) for such a instruction. I was tired of playing GHOT with the ABXY-Hack or with the Guitar Grip, that hurts my hand as hell, so... this was created :q here you go: HOW TO: Make your own Huitar Gero DS Add-On thingy. What you'll need: 4× 270 ? Resistors 2× 2,7 k? Resistors 1× 0 ? Resistor 4× Push-Buttons Old GBA cartdridge or the NDS Lite dust cover drilled board or old PCB from something or simply etch it yourself wire (?) Plexiglas (2 mm thickness) Solderiron (15W max) Solder (0,3 mm to 1,00 mm) Various tools Warning: Spoilers inside! That's basically eveything you need to make a working Add-On for GH On Tour... SH-..., WHERES THE SOLDER IRON?! Just kidding, it wouldnt have fitted on the screen. How to Build! The preperations: The GBA-Slot thing: You simply get an old GBA-Game or your NDS-Lite dust-cover. For GBA-Gamecarts: Since I doesnt wanted to destroy my dust-cover, i just took some shitty roller-scooter-blahfu game and took it apart. I had now the PCB of the cart and the casing. I took the PCB and a x-acto knife and started to cut my way through the copper circuts near the connector-pins. I thought that it would be enough and I took the bloody bastard and broke my way through it's innards with my bare hands. No, seriously, break it with your hands, after you worked with the x-acto on it. That's the easiest way to tear the pin-bar from the other half of the PCB. Warning: Spoilers inside! That's the part we'll need later :q The following part isn't needed if you own a DS Phat After you got the pin-bar, the cartdridge itself has to make its time. I held the dust-cover against the GBA-cart and looked where I have to draw lines, so I will later know where to cut it. So, simply try to make it the size of the dust-cover. And don't forget the notches at the back, otherwise it won't get in the GBA Slot of your DS Lite. Warning: Spoilers inside! Yo, wuts going on here. In the end I've cut the top of the cart off, because I knew there would be some wire looking out, later... ?_?" Warning: Spoilers inside! I fit flush in thy ds. :3 For the ones who would like to destroy their dustcover: Open it, cut off the top and leave anything at it is The "Motherboard": So at this point we'll build the part with the most wires and resistors and.... .... I simply call it "Motherboard" for now, because here is happening the whole magic (blablah you need the Guitargrip in order to play blahblah protection, etc.) Warning: Spoilers inside! The PCB.... Now you know where to solder the different parts. Warning: Spoilers inside! Pin-bar-assignment Warning: Spoilers inside! Okay... and thats how my realization is looking like. Not as fine soldered as it could be done, but it does it's Job: It's working. At this part, there isn't much explaining. The "Fretboard": Okay, the Motherboard was the more difficult part, now we make the fretboard. If you are using a drilled board, please solder the Buttons at one point first and look if it fit to your fingers needs. If it doesn't: De-solder and try it again, a bit more together or more apart. As speaking for myself: I setted up the buttons in "3-dot" gaps on a drilled board with a raster of 2,5mm and it is just fine. Warning: Spoilers inside! It is just fine. After you've soldered the buttons on... whatever you solder on.... look on which pins it does "press the fret" Simply try it with a battery and a LED. I made the mistake and instead of pressing the fret ingame i was releasing it. *facepalm* I had a great Idea for the GND-Wire: So i won't have 4 wires late, I took one and soldered it on one of the Buttons, then I layed it down and looked where i would have to solder the other three and marked it with my water-proof pen. i took the wire again and scratched little holes out of it.. idk how to explain this part.... hm... just look: Warning: Spoilers inside! Not phenomenal, but I like it. Oh, and look at that, the buttons are already soldered! Since here isn't too much about reading too, heres the circut for the fretboard Warning: Spoilers inside! wat. Warning: Spoilers inside! That's mine. Again. ?_?": This would be the assembly or wiring I think. You solder the GndBYRG Parts from the Fretboard with the GndBYRG Parts from the Motherboard. When done, you simply glue the Pin-bar in place in the GBA-cart housing or dust-cover. And guess what? SOLDER D: When you've soldered the Cables from the Motherboard to the pins described above, simply screw the gba cart or dust cover together and stick it into your DS/Lite. If you've worked well enough, you can play now GHOT with your own Grip-Like add-on. ... at least it should feel better than with the ABXY-Hack Arm7hack. Warning: Spoilers inside! The glory of an assembled, selfmade GHOT add-on D: Housing for the selfmade add-on: Follows when my plexiglass arrives here. ©2008 This how-to is property of darkangel5000/darkangel5855/darkangel/darki or whatever I'm nicknamed on any website.
