You can use the Gateway with a system ranging from over 4.5 and less than 9.2 (included) only if you have a Wifi connection with internet. Then you connect to the Gateway website with the internet browser of the console and then the exploits goes on and you are in Gateway mode. But the problem I solved here is: when you don’t have internet wifi available, when you are outside your home, in a train, a car or anywhere with no wifi connection? Then you can’t use your Gateway. So I thought about a solution... I named this solution the Gateway 3DS Traveler, version 2.0 is current one. I designed it as a DIY work electronic project. Some asked me if a version to sell could be possible. So I designed a clean PCB, a 3D model design and bought a 3D printed (this was planned since long, but usefull for this project). And then I realized a complete version prototype ready to reproduce to sell to those not willing to buold themselves. My project and the way to do it all yourself is explained, and the ready to sell version prototype now ready are all on the same website: http://pascelectric.wordpress.com/ Short presentation of the lithium ion battery powert pack with Gateway 3DS traveler: Longest presentation of the 3XAAA battery pack and Gateway 3DS traveler: The Gateway Traveker works for 3Ds with system ranging from 4.0 to 9.2. It works for Gateway 3.0 and 3.1.1 exploit . It worked with Gateway 3.0 launcher file (tested), then with gateway 3.1.1 launcher file (tested). It works only if your 3DS can laucnh the Gateway exploit with internet connection. Then you can use my traveler with no internet connection. If you can't manage to launch Gateway mode on your 3Ds the normal way (without my traveler), then don't considere to use the Traveler: it won't work as a magic trick. It allows you not to have wifi internet access to use your Gateway mode everywhere (with the Traveler inserted in the casing of your 3DS). I computed prices for the selling versions (including electronic items, plastic printed casings): 24€ ($26.10) for Gateway 3DS traveler 2.0 with USB output 600mA (only for emergency and not long recharging of 3DS) + 3XAAA battery pack connector (no battery included) + 3DS recharging cable for USB. This solution fits right is a 3Ds classic casing with a 3DS classic inside and you can close the casing (obviously it fits too in a 3DS XL casing) 16€ ($17.40) for Lithium ion power module (with electronic protection against undercharge, overcharge and overcurrent consumption with LEDs) + micro USB cable to recharge lithium module + digital display of battery voltage + lithium ion battery 2200mAh included + USB output 1Ampere (1000mA) able to recharge a 3DS totally discharged. You can moreover use it to recharge your smartphone, tablet or something else, so this lithium battery pack has other uses than only 3Ds (it is pluged on the Traveler module and can be unpluged easily for other use): money not wasted only for 3DS! This solution fits only in a 3Ds XL casing, not a classic 3DS casing. I ordered the electronic components to build 10 Gateway traveler 2.0; 10 AAA battery pack modules, 10 lithium ion modules. All prototypes are achieved and operational. I just have to wait a missing component set and a missing cable set from my furnishers to come (ordered since 1month and 3 weeeks from china, to have good prices on those devices). If you are interested ina pre-order (no payment, only booking of a unit) then send email with email on the website previously indicated. If you want to builf it yourself from scratch, I gave all programing and electronic informations so that you can do it. My purpose is not to make money since for now I bought many electronic components (200€), filaments for 3D printer and spent more than 200 hours on this project with no money entry; and the price for selling compensates the price of buying components and a little benefit paid at least 1/4 of legal time salary for the assembly of a unit. It is a hobby activity. I began it for my son and he is happy to have now the firts prototype I presented on those pictures for him. If this develops because more than 10 persons are interested, one of my friend and neighbourg will do the job of mass assembly all day, he is voluntary for it (and I can loan my material to him to make production). For now I have only one pre-order, and he told me to inform you on the forum of the existence of the product; so I did it.
