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:
