Sonic The Hedgehog Genesis (GBA) - Lives Underflow Glitch -

If only I found this glitch exactly one month ago!
The Labyrinth 2 Skip found by Werster is needed for this glitch:

Not particularly interesting considering how bad this port is but it's always worth documenting I guess.

The “Sonic has passed” line has never been more fitting

[@IvanFranco120]

LOL. 😅

[@stevenpavelish6017]

Morbid...

[@Sbb911]

Sonic has passed "away" 🤣

[@ryanr27]

SONIC HAS PASSED *GAME OVER*

535 lives in Sonic the Hedgehog Genesis GBA? Wow!

[@jeffycheerios]

Yea but in the OG game ITS 255

[@IvanFranco120]

Maybe the GBA memory RAM changed the overflow limit.

[@Useott]

It's most likely 65535 (16-bit integer limit), but the developers never expected you to go past 999 so it only show the 3 last digits.

YOOOOOOOOOOO this is a great find! I'm using this the next time I play through the game. ...if I can ever bring myself to play through this trash again.

[@IvanFranco120]

Yeah, LOL. 😅

[@FunkyStudios]

Finally, I can beat the boss battle at the end of act 3.

“ you did it you beat the level or not spike

[@Pals-ri3ig]

SONIC Has Passed Game Over

[@fg87sonic]

Oh my God you got 535 lives best glitch ever

[@sackerlacker5399]

I’ve never seen the goalpost under water

[@oosha2000]

What if the game over music ended before act clear ? Would it be counted as loss ?

[@oosha2000]

1 Does it work on the original version ? 2 What about the 255 live glitch ? I mean that one when sonic is about to drown hanging the column and approaching the spikes causing that overflow.

[@IvanFranco120]

The wall clip in Act 2 dosen't work in the original, due different engine physics used... The slowdown in the GBA is what caused Sonic to be pushed inside the wall. As for the lives overflow bug, needs some testing...🤔

[@ChristheBroken]

Also, the Genesis was more reliant on hexadecimal for its programming. The highest number in hex is 255, therefore the highest life count it could jump to was 255

[@Sessho_Setsuna.]

I can't believe this...

[@Sonic2903]

Ahahah magnifique trouvaille que voilà

[@IvanFranco120]

LOL, this didn't happened in the original game...😂 Also, how does the counter now overflow to 535, instead of 256 lifes? 🤔

[@MilsTailsPrower]

They changed it in this port for some reason.

[@IvanFranco120]

@@MilsTailsPrower Yeah, it seems to be an GBA byte loader working differently, than in the original game...🤔

[@ChristheBroken]

The original game uses a hexadecimal system for things like life count. As far as numeric values, hex can only go to 255. Obviously you could manually increase your lives, but because 255 was the highest hexadecimal number, thats where it goes when it can't handle-1

[@s_rewr1991fanbro]

hmmm... this glitch familiar

[@markofthewolvessucks8930]

How do you this ?

[@MilsTailsPrower]

First of all , I used the glitch found by Werster to skip the entire stage. (I will now add it into the video description.) - kzbin.info/www/bejne/b6GbmKWGa7GZhNU Then it's very simple , you need to have 1 life left and beat the stage while Sonic is drowning. You will respawn on Labyrinth 3 with 0 life , dying once more will bring the lives counter to 535.
