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.
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.
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
