can you use the same setup to do fpg on pal as it is on north american version?

Yes but in PAL you get ffpg

ok thanks

what is ffpg lol

But it doesn't save time technically cuz 50 fps compared to NTSC's 60 fps

Nah that's not how it works. I don't know if you can use the same setup, but you won't get ffpg out of it. The PAL ffpg is not viabe for humans. @SzukiX_ FFPG is Full FPG which is basically a BBG without a bullet.

Oooh my apologies then, I dont play on PAL nor do I ever think to play on it so my knowledge is minimal

The Sockfolder setup for doing FPG on the NTSC version will not work on PAL SMB1, because of the different physics. There is, however, an RTA setup for doing FPG (the normal FPG, not full FPG) on the PAL version which (to my knowledge) involves landing before the flagpole with walking speed and then jumping on a particular frame. I don't know the specific details of the setup, though.

Watch the FPGs in this and you can see the inputs on the right. Just land on the correct spot before the flag while not holding B and jump very close to the block.

How did you get into the block at the end of phase 1-2?

Jump from a specific spot on the elevator, for an exact number of frames (don't remember how many, but you can check the video) and you'll fall right through the floor.
