hi, by any chance is there a SMB1 hack ROM with Mario who, instead of going to the right, goes to the left? Everything else the same as the original! can I do it myself? what should I change in the code? THANK YOU

Where I can find an autosplitter for BizHawk?

thanks.

why does the NTSC version have two different demos? does it have to do with colliding with enemies? and why does the PAL version only have one demo? Thank you.

I discovered a strange behavior in my FCEUX. in version 2.1.0 if I run to the right and then ALSO press left, mario will stop. Instead if I press right and then left in version 2.6.4, mario stops... and goes back to the left!!!! it also happens in jumps! I use keyboard. I use same ROM (it's super ok), and I disabled L+R of course. Can anyone explain why this happens? Am I doing something wrong in the settings? thanks.

Technically, WHY the plant are invisible??? Thanks.

specifically the 3 parakoopas part. how many patterns are there? I know framerules, and I know kosmic's method of slowing down 2 frames and then going under the first guy and over the rest, but are there any techniques to know if i were to slow down for example 3, or 4, or 5 frames? is there a spreadsheet about it? purely for scientific interest. thank you.

and more: what is bbbb technique? thanks!!!

Hi everybody! I cannot find a complete technical explanation of how to cause the flagpole glitch! (I don't wanna an explanation how to do the glitch i.e. inputs, thanks)
