This section contains 3DS-related programs for the computer. That is to say, they are not running on the 3DS, but on your PC. Tools, file formats and techniques for editing commercial games are also discussed in GBAtemp's 3DS hacking section which will have additional information. Many tools are useful across systems (a hex editor works much the same regardless of the system you are working on) so do also check out the Filetrip's general programming tools section.
Spoke to Tom Fulp the other day, if he can find his old Newgrounds site content like the mini Flash animations from the 2000's that played on the portal.
@SylverReZ, atleast the 1999 versión of pico's school is avaliable (the difference between it, the 2006 versión and the 2016 versión is that the speed of the game depends of the speed of your computer and that it had the og soundtrack)
@SylverReZ, although the "secrets" system where the game was has been removed. Also pico vs uberkids had a netplay versión that was shutdown, although the swf file has been found
@Xdqwerty, Nope. There are two download buttons on the same page, where you can download the original under a file called "bear.exe". "bear2.exe", however, is the updated game in a Flash projector. P.s. this was on the archived Pico page from 2000.
Fun fact @SylverReZ: iirc one of the goals on the fnf Kickstarter stated that pico 2 would be finished but the Kickstarter didnt get enough money for that goal to be fullfiled
