Hello,
I dumped the nand twice through the lpt port - nands are the same.
Then I dumped the nand twice through the USB port (matrix nand reader) - nands are the same.
When I compared the two nands usb and lpt - 66 non-matching block (s) found
I dump only 64mb.

Code: 
4096 block(s) in nand image
66 non-matching block(s) found

Why does this difference occur?

Both nands open normally with jrunner and autogg.

indeed, I think at the end of the nand iirc. the first fifty blocks are for xell, which can be good for flashing the nand in case it gets corrupted. I've done that with debian disc and just normal xell. I think in either case, xell must be bootable. anyway, my wii's nand has bad blocks from the factory too, so it's normal, but it's only like five or six bad blocks. that's when I backed it up. it will show a black square for every bad block.

  • Xdqwerty @ Xdqwerty:
    Also somebody is remaking it
  • SylverReZ @ SylverReZ:
    @Xdqwerty, Reason how I found Newgrounds: https://www.newgrounds.com/portal/view/249365
  • Xdqwerty @ Xdqwerty:
    @SylverReZ, the other game where I found newgrounds is new york shark

  • SylverReZ @ SylverReZ:
    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 @ SylverReZ:
    So far no response, but he did say that he'll find them. Wayback Machine doesn't have em.
  • Xdqwerty @ Xdqwerty:
    @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 @ SylverReZ:
    @Xdqwerty, Another being Pico VS Bear, the original 1999 version before Jim Henson filed a DMCA takedown.

  • Xdqwerty @ Xdqwerty:
    The 2006 versión was made when the flash portal was made
  • SylverReZ @ SylverReZ:
    Many people thought it was lost, but was discovered that he hid it on the same page.
  • SylverReZ @ SylverReZ:
    https://tcrf.net/Pico_VS_Bear
  • Xdqwerty @ Xdqwerty:
    @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
  • SylverReZ @ SylverReZ:
    @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.
  • SylverReZ @ SylverReZ:
    @Xdqwerty, That's been there for a long time, too. People who search for lost media don't look hard enough lmao.

  • Xdqwerty @ Xdqwerty:
    @SylverReZ, also the pico 2 demos used to be only for the newgrounds patrons but they are on internet archive too (https://archive.org/download/picos_school_2)
     +1
  • Xdqwerty @ Xdqwerty:
    Iirc the demos were removed from newgrounds in 2022
  • Xdqwerty @ Xdqwerty:
    @SylverReZ, or well only the demo with mindchamber's style was on newgrounds
     +1
  • Xdqwerty @ Xdqwerty:
    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
  • SylverReZ @ SylverReZ:
    @Xdqwerty, FNF sucks, their community is toxic as hell.
  • The Real Jdbye @ The Real Jdbye:
    @SylverReZ its a single player game
  • Xdqwerty @ Xdqwerty:
    @The Real Jdbye, Yea but it has a shitton of mods with their own songs and stuff
  • Xdqwerty @ Xdqwerty:
    @The Real Jdbye, and quite a lot of people involved in those mods get cancelled
  • SylverReZ @ SylverReZ:
    Newgrounds wasn't the birth of FNF; rather, it was games where you beat up celebrities and parodies.
