I may have found a bug? Like a real bug...

Tried running this on my Gameboy Color.

I am using the EZ Flash Jr ver: FW4 k1.04e. The game loaded fine etc but when it comes to play, holding Right on the d-pad causes the character to run at break neck speed, whereas holding Left he walks normally.

Tried the browser version to see if this was a 'feature' and its clearly not lol

So not sure if it's just happening on my flash cart (I tired a few other roms to be sure its not happening on other games and they play fine) or if this is a bug in the .gb file, but as I'm not a speed runner it makes the game basically impossible for me to play lol

Just happened to me before, got it on tape and I'm rendering it out as we speak. Not the first time as well as I was able to do it on the title screen a couple days back.

I will post the video here once it uploads to youtube. My theory on how to recreate the glitch is pressing right on the first frame of the level, I believe that what I did but I truly don't know.

Calling it the FAF (Fast As F-word) exploit cause it sounds cool.

I do my runs on BGB 1.5.8SR btw.

so many deaths

omg if this was a category I would die trying to run it lol

well it could be if find out how it works

so the person had the glitch on EZ Flash Jr ver: FW4 k1.04e acordding to there post do you it more easy to do on a flash cart?

An EZ Flash Jr is a GameBoy flash cart which just means they did it on original hardware. I did the glitch on BGB which should be near 100% accurate to original hardware. Not sure if its possible on web because I don't know if its a completely different version or some web based GB emu.

Gonna mess around in TAStudio and see if I can recreate it.

did you find a answer to why it happen
