[UPDATE]
I've just figured out, you only can scroll throughout the dimensions you set in the LoadMap function, as I had this space filled I can't scroll the image.

Right now I'm wondering if a map that has the screen size or less can be scrolled...which is totally absurd, but now I think this is the actual problem

[UPDATE2]
WTH? I don't know why, but in 0.6 the maps are correctly processed and displayed, also seems that the scroll problem really was due to map's width and height, but in 0.7, with the correct dldi patch they have lots of graphic errors. I think that the errors weren't there when I tried the program on the DS before, so why do they appear now?
For 0.6 I'm packing the files and for 0.7 I have them in a directory on my card.

Hi all, I've written this little function as to load maps an easy way to use them as backgrounds but I'm having some trouble:
note: the function is in another file than the main program.
function LoadBG( map, screen, width, height, text )
map_raw = map .. ".raw"
map_pal = map .. ".pal"
map = map .. ".map"
if screen == 1 then
BGTop = Screen.LoadTileBG()
BGTop:LoadPalette( map_pal )
BGTop:LoadTiles( map_raw, 256 ) -- 256 colours
if width == 0 and height == 0 then
BGTop:LoadMap( map, (256/8), (192/8) )
else
BGTop:LoadMap( map, width, height )
end
if text == 1 then
BGTopText = Screen.LoadTextBG()
Screen.Initialize( screen, BGTopText, BGTop )
else
Screen.Initialize( screen, BGTop )
end
else
BGBot = Screen.LoadTileBG()
BGBot:LoadPalette( map_pal )
BGBot:LoadTiles( map_raw, 256 ) -- 256 colours
if width == 0 and height == 0 then
BGBot:LoadMap( map, (256/8), (192/8) )
else
BGBot:LoadMap( map, width, height )
end
if text == 1 then
BGBotText = Screen.LoadTextBG()
Screen.Initialize( screen, BGBotText, BGBot )
else
Screen.Initialize( screen, BGBot )
end
end
end
LoadBG( map, screen, width, height, text )
map estands for the file name, then the function adds the extensions to the string and stores it in different variables.
screen is 0 or 1, 0 for bottom and 1 for top
width and height are the size of the map, if 0 is put in there, then the functions falls to default 256/8 and 192/8.
text is also a number. If it is 1 (enabled) the function loads the background after loading a text background, so we have a background capable of being printed text over.
All works fine (background displaying and printing text over it) but for some reason I can't scroll the images (256x192 both top and bottom images).
If everything is right, top map should be in BGTop and bottom one in BGBot, so to scroll the top one i'll use BGTop:ScrollXY( x, y ), but for some reason this don't seem to be working.
