- fixed the broken multiplayer camera
- fixed some softlock scenarios with daisy
- tweaked behavior/appearance of collapsing platforms

If you get bad performance, make sure you have hardware acceleration enabled on your browser. In chrome, go to chrome://settings/appearance, click advanced, scroll to the bottom and make sure that "use hardware acceleration when available" is turned on. Alternately, you can just download the desktop version.

The game window is misaligned. There's a lot of black space. I have a 1440p monitor.
Badspot2017-06-16 15:37:44
Take a screenshot. I also have a 1440p monitor.

Are the sprites taken from somewhere?
It seems like there's these lines that are visible in the default graphics mode.

There's an issue with getting hit while having a powerup- it'll just revert you back to small mario instead of going to big mario
Badspot2017-06-19 12:12:46
>Are the sprites taken from somewhere?

It's based on Super Mario Land for the original gameboy.


>It seems like there's these lines that are visible in the default graphics mode

If you're talking about artifacts near each sprite, that's from texture sampling which I don't have full control over in webGL. It doesn't appear on every computer (not on mine). I have a plan to fix it but it's kind of complicated.


> it'll just revert you back to small mario instead of going to big mario

This is how it is in the original. The extra hit was only added for the US/Europe versions of Super Mario Bros 3 to make the game easier, in other early Mario games you only get one hit.

He abandons blockland for this, hes saying blockland is outdated but he went back 15 years lol.
Rednakin2017-06-29 13:36:33
the thing i complained about is now fixed.

Impressive work! You would make a great programmer!

Thanks, bro. I know I'll make it someday.
Niklassi2017-08-05 10:23:35
Is it possible to add a frameskip option? I have a Low-End PC and it would really help me. Thank you <3
Badspot2017-08-06 01:21:19
If you have a low end PC, I'd recommend downloading the binary version of the game. If it still won't run full speed (you must have a reaaally low-end machine), you can go into the options, change "vsync" from "hardware" to "high timer" or "ms timer" then select 30 fps.

Loved playing this for GB back in the day
John Doe2017-12-01 18:08:34

Anon2018-01-13 02:33:22
The game is good but the shit falling from the roof is so quick it's like a thwomp with x2 speed. Any sequel coming soon?

Isaiah Austin2018-10-13 17:00:39
This is awesome!!! I wanted to play Super Mario Land without downloading an emulator, and this is the best online version of the game I've ever played. Great work!!!
Isaiah Austin2018-10-26 17:27:49
At the end of World 2-3, I keep getting stuck in the ground!
Isaiah Austin2018-10-26 17:28:41
I can't even finish the game!
PixelCrunch2018-10-28 14:08:53
Super Mehrio Lande!
Isaiah Austin2018-10-31 21:55:30
Never mind. Finished it!
Mason2019-01-06 03:51:39
Needs work. Thanks for the automatic Mayflash SNES detection, though. Only persistent nags are the exits, end-level bonus rooms and sound looping. Overall fun and very much worth playing. Did die in the Daisy room twice though, btw. After second boss I loaded to the left of an invisible barrier and after the first boss I got killed by Daisy herself.
Badspot2019-01-06 04:42:25
Running through the exits, and the interactive bonus and Daisy rooms are design decisions and I think they're fun. I would rather interact with something than watch a canned animation. A lot of people get a laugh when they discover that they can preemptively kill daisy with super balls.

Music looping is tricky because they're midi remixes I found online rendered into .ogg files. Also some sound functions are broken in the browser, which is why coin collection sounds stack up instead of repeating - so looping seamlessly might not even be possible.

>After second boss I loaded to the left of an invisible barrier

From dying to Daisy or just from spawning in? Do you have an ultra-wide monitor?

daniel2019-06-03 15:20:51

Oofio2019-07-24 20:40:13
Oh wait nevermind I figured it out now.
daniel2019-07-26 19:43:13
seriously the Wii remote still does not work
Badspot2019-07-26 22:56:50
>seriously the Wii remote still does not work
The browser version uses a magical subset of direct input, I don't know how it works. If you have a problem you're on your own. Plug in an xbox controller.

The downloaded version uses real direct input via sdl, it should display the name of the controller and everything. If you're using some ghetto hacked wiimote driver that doesn't support direct input correctly, you're on your own. Plug in an xbox controller.
Oofio2019-07-26 23:18:06
But what if you dont have an Xbox controller?
