Sorry if I seemed rude! I didn't mean you should be the one who fixes it, just that I really need to find a scripter for this project.
Anyway, I made the changes you said. I also changed every other 320/640 I saw with the right numbers, like here:
Code:
    @viewport1 = Viewport.new(0, 0, 800, 600)
    @viewport2 = Viewport.new(0, 0, 800, 600)
    @viewport3 = Viewport.new(0, 0, 800, 600)
and this is the result:
![[Image: Sp4CX6O.png]](http://i.imgur.com/Sp4CX6O.png) 
 
The map renders almost correctly, there's just this huge black bar on the bottom. Probably I missed some other numbers.
The character remains slightly on the left, but since I want to make a side-scrolling game, this is actually a good news!
However, if the character tries to walk to the left, an huge pool of darkness appears:

And I don't really understand what's causing it.
This is the modified version of the script, hope it helps:

# 
# Introduction:
# 
#   This script can display maps in a type of 3D with depth. It has a low lag
#   factor.
# 
# 
# Instructions:
# 
#   In the editor in the lower left corner is the map list of the maps you
#   are using in your game. You have several options: If you want to make a
#   map use Mode 7 you need to ADD one or more of these text commands to the
#   map's name. Those commands should not appear in the map's name if using
#   a location display script. The options you have are the following:
#   
#   [M7]  : to activate Mode7
#   [#XX] : XX is the slant angle (in degree). Default value is 0 (normal maps)
#   [Y]   : Y-map looping
#   [X]   : X-map looping. This option needs resources (lower fps).
#   [A]   : animated autotiles (with 4 patterns). This option increases
#           significantly the loading time, so it may crash for large maps
#           (SystemStackError)
#   [C]   : to center the map on the hero (even for small maps)
#   [P]   : to have a fixed panorama
#   [H]   : to have a white horizon
#   [OV]  : Overworld Sprite Resize (a Mewsterus's script feature)
#   
#   Alternatively you can define prepared settings that will be triggered with
#   every map that has that specific text included in its name. See the
#   "MODE7_SETTINGS" below to prepare your settings.
#   
#   
# Control commands:
#   
#   You can change the settings on the map in-game and use a couple of
#   additional commands. If you want to use one of those commands, use a "Call
#   Script" event command and type one of the following commands into the text
#   input window:
#   
#   1. $scene.spriteset.tilemap.mode7_set(ANGLE)
#   2. $scene.spriteset.tilemap.mode7_set_p(ANGLE)
#   3. $scene.spriteset.tilemap.mode7_redraw
#   4. $game_system.map_opacity = VALUE
#   5. $game_system.map_gradual_opacity = VALUE
#   6. $game_system.map_tone = Color.new(RED, GREEN, BLUE)
#   7. $game_system.map_gradual_tone = Tone.new(RED, GREEN, BLUE, GREY)
#   8. $game_system.horizon = VALUE
#   9. $game_system.reset
#   
#   1. Redraws the map with a new angle which is specified by ANGLE
#   2. Redraws the map progressively with a new angle which is specified by
#      ANGLE
#   3. Redraws the map (can be useful with the following commands)
#   4. Defines the opacity for Mode7 maps (it needs to redraw)
#   5. Defines a gradual opacity for Mode7 maps (it needs to redraw)
#      (it bugs with horizontal looping)
#   6. Defines the tone for Mode7 maps (it needs to redraw)
#   7. Defines a gradual tone for Mode7 maps (it needs to redraw)
#   8. Defines the view's distance (default : 960) (it needs to redraw)
#   9. Re-initialize the previous options
#   
#   
# Additional commands:
#   
#   1) If you wish to obtain flat events, add a comment in the event's code
#      and type in the word "Flat" without the double quotes).
#   2) You can handle the height of vertical events by adding a comment to the
#      event's code with the text "Height X" (without the double quotes).
#      Replace X with the height value. Example: If you use Height 1.5, then
#      the event will appear floating above its position in a height of 1.5 map
#      squares (48 pixels).
#

#---------------------#
# START Configuration #
#---------------------#
# The map is drawn from all the tiles of the three layers. You can define tiles
# which are not being drawn flat, but vertical which creates the impression
# that the objects would be standing upright.
# To define such tiles, add one or more terrain tags to this array and separate
# them with commas. In your tileset database gives those specific tiles one of
# those terrain tags and the tile will be drawn vertically.
VERTICAL_TILE_TERRAIN_TAGS = [1, 2]
#   You can create packages of settings which are automatically triggered if a
#   map name includes the text corresponding to the setting. Use following
#   template to create such settings:
#   
#     MODE7_SETTINGS['CORRESPONDING_TEXT'] = ['SETTING_1', 'SETTING_2', ...]
#   
#   CORRESPONDING_TEXT - text in map name
#   SETTING            - one of the settings from the instructions WITHOUT the
#                        [ and ] brackets (i.e. instead of [H], use just H)
#   
#   You can add as many settings as you want. There are two predefined settings
#   to make you understand easier how it works.
MODE7_SETTINGS['World Map'] = ['#60', 'X', 'Y', 'H', 'P']
MODE7_SETTINGS['Smallslant'] = ['#20', 'A', 'S']
