I just made my own Gameboy Test Cartridge ROM!

I used GB Studio to make it, and it took me a few hours of messing around to get it working, with zero prior knowledge of how to use GB Studio beyond making a splash screen, lol.

v1.0 - Initial release, has Button Test.
v1.1 - Now has a main menu. It contains button test, and a screen test. You can now easily identify any screen-tearing on IPS screens, dead pixels, vertical lines, or ghosting.
v1.2 - Now has a Sound Test on the main menu. After playing the sound, it returns back to the main menu.

DOWNLOAD: HERE

I know, but I hate that one. With mine, you can test the same buttons repeatedly. Endlessly.

@The Real Jdbye it's for detecting hardware failure, testing pad continuity, controller configuration in emulators, etc. No promises, but if I can add a menu with different option, I'll add in a screen-tearing test, dead pixel test, and a grid pattern for vertical line checking.

New version just released, v1.1 has been uploaded. I added in a menu and a scrolling screen test pattern I made. It scrolls in 8 directions, about 3 seconds in each direction in an endless loop. Good for testing to see if IPS screens are having screen tearing issues, if your screen has missing lines, or stuck/dead pixels. Updated the first post with the new version and screenshots I recorded from mGBA.

@Crazynoob458 I just read on their twitter that they have a new version coming with 3-layer parallax scrolling, large sprite support, .wav sound effects, and a new sound engine that even allows you to sync the music to scripts! And best of all, it still keeps the .mod support, so now we'll finally have more music options.

No problem. I release this ROM as public domain.
It uses the MBC5 mapper. So feel free to flash it to a bootleg cartridge and sell it if you want, I really don't care! :grog:

  • 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.
  • 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)

  • 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

  • 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.

    FNF was born from Game Jams
