Why do I turn into super Mario instead of fire Mario when I touch a fire flower AS SMALL Mario in Super Mario Bros 1?

When I was playing Super Mario Bros 1, I - as Super Mario - hit a block containing a fire flower. I then got hit by an enemy, changing me into small Mario, but the fire flower was still on-screen.

When I touched the fire flower as Small Mario, it just turned me into Super Mario instead of Fire Mario.

Why does this happen?

For a technical explanation, if we look at the disassembled code for Super Mario Bros, we can see that the routine for collecting fire flowers and super mushrooms is exactly the same.

HandlePowerUpCollision: jsr EraseEnemyObject ;erase the power-up object lda #$06 jsr SetupFloateyNumber ;award 1000 points to player by default lda #Sfx_PowerUpGrab sta Square2SoundQueue ;play the power-up sound lda PowerUpType ;check power-up type cmp #$02 bcc Shroom_Flower_PUp ;if mushroom or fire flower, branch cmp #$03 beq SetFor1Up ;if 1-up mushroom, branch lda #$23 ;otherwise set star mario invincibility sta StarInvincibleTimer ;timer, and load the star mario music lda #StarPowerMusic ;into the area music queue, then leave sta AreaMusicQueue rts
Shroom_Flower_PUp: lda PlayerStatus ;if player status = small, branch beq UpToSuper cmp #$01 ;if player status not super, leave bne NoPUp ldx ObjectOffset ;get enemy offset, not necessary lda #$02 ;set player status to fiery sta PlayerStatus jsr GetPlayerColors ;run sub to change colors of player ldx ObjectOffset ;get enemy offset again, and again not necessary lda #$0c ;set value to be used by subroutine tree (fiery) jmp UpToFiery ;jump to set values accordingly

I would say this is intended behavior. If you somehow could get a super mushroom onscreen while you were Super Mario, he would turn into Firey Mario. Most likely, the rationale is to save space on the ROM.

Yes as the weakened Mario the game script only allows 1 stage progression from in level items so anything for small Mario(1 hit to kill) go to super mario(2 hit to kill), then only if the item is tir 3 fire flower will grant the special mario(3 hit to kill).

I always saw it as a 3 stages of Mario

Mini - Big - Fire

And the powerups do not just do +1 to the stage counter. They just boost you up to the appropriate stage (if the stage is higher than the current.)

Like if you get a mushroom and already is on the Big stage, you will not go up to fire, you stay big.

So when you touch a fire flower, that you would be Mini or big it boosts you up to Fire stage. Its like if the mushroom is always included in the flower.
