i was practicing 2-1 with pellsson rom, got to the end, but suddenly, the spring despawned as i got close to it (not the small brick part, just the red spring) and when i landed on it, i got stuck in place and couldn't move. I could run or walk, and it'd have the speed of the moving animation, and i could turn around with its animation, but i would never move. The time would tick, so I could either wait and die or restart, and have it happen again.
Yeah, that's a bug present in the original NTSC release of the game, not an issue with the practice ROM. This occurs because springs are allowed to load into the sixth enemy object slot (usually reserved for power-ups and the flag atop the flagpole), so the spring in 2-1 will get overwritten by the flagpole's flag if it loads into this slot. It was fixed in the PAL version, SMB2J, and the All-Stars re-release.
woah, didn't know springs went in slot 6. Does that mean you have to kill the plant before it loads so it doesn't despawn?
Effective immediately, any submissions using the SNES9x emulator will not be verified. The SMB1 mod team has concerns about its integrity due to its ability to overclock and remove lag frames, which may not be easily detectable. Additionally, we request that all BizHawk submissions avoid using the S
