I'm talking with the Randomdude in the Discord about the Boohemoth LevelASM code.

The "Boohemoth" code is an Auto-scroll, but only can be stopped when the player is facing left.
THIS IS WHAT I'M TALKING ABOUT!!

Code

init:
main:
LDA $76
BEQ .end
LDA $1462|!addr
REP #$20
CLC : SEP #$20
ADC #$01
STA $1462|!addr
.end: RTL

Using the code above works, but only reacts 2 screens, afterwards, it can return to the screen 00.

Code

init:
main:
LDA $76
BEQ .end
REP #$20
LDA $1462|!addr
CLC
ADC #$01
STA $1462|!addr
SEP #$20
.end: RTL

Using the code above cause the black screen (freeze the game).

Can anyone help me?

In the second code, change:

Code

ADC #$01

Code

ADC #$0001

My conversation in Discord with randomdude, we have this:

Code

init:
main:
LDA $76
STA $14AF|!addr
BEQ .end
LDA $14
AND #$01
BEQ .end
REP #$20
LDA $1462|!addr
CLC
ADC #$0001
STA $1462|!addr
SEP #$20
.end: RTL

This is the Boohemoth auto-scroll code, this auto-scroll works if the player is facing right, however, when the player faces left, the Auto-scroll stops. These triggers the ON/OFF flag.

But there are two issues...

1) Customization speed, because the auto-scroll code is a little too slow.
2) The Auto-scroll is unstoppable.

Can anyone help me?

In order to customise the speed, you have two options:

-changing

Code

CLC
ADC #$0001

Code

CLC
ADC #$0002

or higher will make the autoscroll quicker.

-changing

Code

LDA $14
AND #$01

Code

LDA $14
AND #$03

or another power of two minus one (#$05, #$07, etc) will make the autoscroll slower.

Try playing with both changes until you find a good speed.

Add a check to $5E. Like:

Code

	LDA $1B
	INC
	CMP $5E
	BCS .end
	; rest of the code

If you're remaking the Boohemoth, don't forget that after looking left for awhile the autoscroll continues at half speed until looking away again.

I found another problem with the code.
When pausing, it cause glitches on the screen.

I used something like...

Code

init:
main:
LDA #$10
TRB $15
TRB $16
LDA $1B
INC
CMP $5E
BCS .end
LDA $76
STA $14AF|!addr
BEQ .end
LDA $14
AND #$03
BEQ .end
REP #$20
LDA $1462|!addr
CLC
ADC #$0001
STA $1462|!addr
SEP #$20
.end: RTL

But this doesn't work.
How can i fix this?

Try looking at the SMW ROM map.

For the record, that... doesn't really help.

Anyway, to fix the pause issue, check $13D4 instead. That indicates whether the game is paused; if non-zero, return.
