Whatup all folks! I sure each game has it’s own rules pertaining to this, but i just want to see the general consensus: is GBi allowed for speedrunning in most scenarios? It’s using nintendo’s hardware, and it’s not emulation, it just looks WAY better and does not require a disk to use. Do most GB, GBC and GBA allow for use with GBi?

all it is is a different interface for the GBP (hence the name), so yes it should be allowed for all GB/GBA games.

I'm from the GB community, and GBi and SGB2 are our hardware standards. 

I can't speak for GBA or GBC, but you'll be accepted with GBi on nearly every GB board if not all of them.

Awesome man, i’m glad. That disk is too expensive and that screen is not 240p enough on GBP haha

Can confirm: GBi (on either the deprecated LL (=low latency) or the more recent speedrun setting) is one of the standards for Game Boy speedrunning. For more information about GB speedrunning you can also visit http://www.gbrunners.com/game-boy-speedrunning-explained .
