[Tutorial] How to extend Sonic 1 Debug Mode (Macro AS)

So if you want to extend Debug Mode for Sonic 1 Macro AS, you should go to _inc/DebugList.asm on your disassembly.

For this, you will see this single monitor code:

Code:

        dbug    Map_Monitor,    id_Monitor,    0,    0,    make_art_tile(ArtTile_Monitor,0,0)

If you want make sure that the monitor does not do anything like, you want to extend it like in RSDK version? Here it is:

Code:

    dbug    Map_Monitor,    id_Monitor,    7,    9,    make_art_tile(ArtTile_Monitor,0,0) ; S Monitor
    dbug    Map_Monitor,    id_Monitor,    4,    6,    make_art_tile(ArtTile_Monitor,0,0) ; Shield
    dbug    Map_Monitor,    id_Monitor,    3,    5,    make_art_tile(ArtTile_Monitor,0,0) ; Speed Shoes
    dbug    Map_Monitor,    id_Monitor,    5,    7,    make_art_tile(ArtTile_Monitor,0,0) ; Invincibility
    dbug    Map_Monitor,    id_Monitor,    6,    8,    make_art_tile(ArtTile_Monitor,0,0) ; 10 rings
    dbug    Map_Monitor,    id_Monitor,    2,    4,    make_art_tile(ArtTile_Monitor,0,0) ; Sonic 1UP
    dbug    Map_Monitor,    id_Monitor,    1,    3,    make_art_tile(ArtTile_Monitor,0,0) ; Eggman
    dbug    Map_Monitor,    id_Monitor,    8,    10,    make_art_tile(ArtTile_Monitor,0,0) ; Goggles

For other items, you should replace the one

Code:

        dbug    Map_Bonus,    id_HiddenBonus,    1,    1,    make_art_tile(ArtTile_Hidden_Points,0,1)

With

Code:

    dbug    Map_Bonus,    id_HiddenBonus,    1,    1,    make_art_tile(ArtTile_Hidden_Points,0,1)
    dbug    Map_Bonus,    id_HiddenBonus,    2,    2,    make_art_tile(ArtTile_Hidden_Points,0,1)
    dbug    Map_Bonus,    id_HiddenBonus,    3,    3,    make_art_tile(ArtTile_Hidden_Points,0,1)

And okay, if you want one more objects like Signpost or bosses. Here it is.

For Signpost

Code:

    dbug    Map_Sign,    id_Signpost,    1,    0,    make_art_tile(ArtTile_Signpost,0,1)

For Eggman Prison

Code:

    dbug    Map_Pri,    id_Prison,    2,    2,    make_art_tile(ArtTile_Prison_Capsule,0,1)
    dbug    Map_Pri,    id_Prison,    1,    1,    make_art_tile(ArtTile_Prison_Capsule,0,1)

For Spring

Code:

    dbug    Map_Spring,    id_Springs,    0,    0,    make_art_tile(ArtTile_Spring_Horizontal,0,0)
    dbug    Map_Spring,    id_Springs,    2,    0,    make_art_tile(ArtTile_Spring_Horizontal,1,0)
    dbug    Map_Spring,    id_Springs,    $10,    3,    make_art_tile(ArtTile_Spring_Vertical,0,0)
    dbug    Map_Spring,    id_Springs,    $12,    3,    make_art_tile(ArtTile_Spring_Vertical,1,0)

Here it is, now you got the extended debug mode for Sonic 1. You can do the same process but for the zones, one bonus is the Spring thing.

Happy hacking!
