Ah good, I was about to post to ask the question. Li-ions have a stated voltage (under load) eg 3.7v; but a voltage which is higher when not under load, or little load; yes, the NDS Lite cells can get to 4.2v after recharge. I was going to ask if 4.2v would fry the GP2x, the fact Squidge says...

Sure, will let you know if this is good to go or not. Will probably test tomorrow or following day, to see. With one of these batteries, it could be made to fit into the existing 2 x AA cavity, so the back plate can be shut as per normal. Trick is the battery life, which is the important thing...

1 battery 1800mA, two in parallel 3600mA. Might be a lame duck, only by testing until the GP2x dies will a definitive answer be gained. Might give this a go in a week's time or less, to find out. Just need to solder the battery wires to the GP2x connectors and let it run. Point is that if the...

Not even turned on my GP2x for ages now, I recently tried some NDS Lite Li-ion batteries to power a PSone screen and some plug'n'plays; didn't prove a great choice as I only got 50 mins from them whatever I did (2 of them in series as each cell is 3.7v), even when two sets of series cells were...

Look in his video, action game. Be impressed!

I was referring to hobbyists rather than people who have the ability to manufacture their own boards, commercially! A mill, or CNC equipment, or whatever is not practical and I have no access to anyone who has either, I only make for me (although I may make something in the future to sell...

Yes, people should look at the abilities not just looks. My system is unique, one of a kind; who else MAKES systems into cartridges and then makes them work into a universal cart slot?? Didn't use any paper on the console itself, only the carts. Needed to stick my artwork onto the case, paper...

No, your video is still there!

YouTube video Project step-by-step guide on my website (see sig). TV plug'n'play systems have great games on them, but the controls are pretty bad; the systems are also not portable as they need to plug into a television to play a game. With my system, a plug'n'play system is ripped apart and...

Indeed, works great. Nice to see you like it. BTW - have a look on my website - built an awesome new portable!!

Firstly EVERYONE - someone who finally did my (crude) mod and gave feedback about it - "Yeah, I don't know why people knocked this mod. It actually works pretty well.....it's worlds better than the joystick." I doubt I will get any apologies from the numerous idiots who slated my work a couple...

At last - someone tried my "ugly d-pad mod". I was getting pissed off when people at the time were slating it without trying it. I kept telling them that it worked fine and better than the stock joystick. Downside with it was that it worked for quite a while but wasn't permanent as I didn't use...

Use a dremel or similar tool: Circular cutter to slice through mobo. Sanding drum to GENTLY rub off the covering to get to the copper traces. Drill bits to cut the holes. Look on my site if you like, as part of my project (eg current Mini-Multi Platform Console system) shows how to do it.

The way buttons register is actually rather simple. You have a (common) ground one on connection and one for the button itself (eg "up" or whatever). When you press that button the two contacts connect completing the circuit. Ground is common as it is used for all connections, and ground is...

With thousands of games via emulation available, many of them quality, why buy any??

At some point I am going to modify my main GP2x with a pair of NDS Lite batteries in parallel, each one is rated 3.7v, although they register 4.2v; a pair of them in parallel will rate at 3600mA and being Li-ions, will have more oomph! I will also put in a sleek d-pad; however I have other...

Battery terminals - open up any remote control or whatever that uses batteries and desolder the terminal tabs; you can then desolder the ones on the GP2x and solder on the new ones. D-pad mod - plenty of guides on this forum for doing that. Then, your issues are resolved, good as new.

Fourth generation. Some excellent games with real gameplay, and still relevant today.

You can easily find the contact points by using a multimeter - one terminal on ground connection, one on a direction pin, press d-pad, then you can work out what is what.

Ok, got your PM mate. Been ages since I looked at this old mod of mine, it was my first modding experience and my skills were totally shite in comparison to now. The joystick is the same for MK1 as MK2, however it was rotated a bit on MK2. The orange and red wires must be grounding...
