A long time ago i found this code that allowed to give a x2 zoom on bitmaps with a filter like the ones from the 16bits emulators
the result is great but since ruby get pixel and set pixel is slow as hell, it's not something usable.
I know that it's possible to make a dll to use winapi to do this work faster, but since my C/C++ knowlegde is near nil i can't seem to make this work.
Code:
#==============================================================================
# ** Bitmap
#------------------------------------------------------------------------------
# This class handles and draws the bitmaps
#==============================================================================
class Bitmap
#--------------------------------------------------------------------------
# * New method: x2
#--------------------------------------------------------------------------
def x2
bitmap = Bitmap.allocate
bitmap.send(:initialize, width * 2, height * 2)
width.times do |x|
height.times do |y|
px = get_pixel(x, y)
x2 = x * 2
y2 = y * 2
p1 = x == 0 ? px : get_pixel(x - 1, y)
p2 = x == width - 1 ? px : get_pixel(x + 1, y)
p3 = y == 0 ? px : get_pixel(x, y - 1)
p4 = y == height - 1 ? px : get_pixel(x, y + 1)
if p3 != p4 && p1 != p2
bitmap.set_pixel(x2 , y2, p1 == p3 ? p1 : px)
bitmap.set_pixel(x2 + 1, y2, p3 == p2 ? p2 : px)
bitmap.set_pixel(x2 , y2 + 1, p1 == p4 ? p1 : px)
bitmap.set_pixel(x2 + 1, y2 + 1, p4 == p2 ? p2 : px)
else
bitmap.fill_rect(x2, y2, 2, 2, px)
end
end
end
bitmap
end
endthe result is great but since ruby get pixel and set pixel is slow as hell, it's not something usable.

That is ok. I know the rest of the Actor 3 Set...
so hopefully tomorrow i get to go home from the hospital i've been here for 5 days already and it's driving me mad. I miss my family like crazy but at least I get to use my own toiletries and my own clothes. My mom is coming to visit soon i can't wait to see her cause i miss her the most. 
Holy stink, where have I been? Well, I started my temporary job this week. So less time to spend on game design...
Cartoonier cloud cover that better fits the art style, as well as (slightly) improved blending/fading... fading clouds when there are larger patterns is still somewhat abrupt for some reason.
