Angry birds demo in MegaDriver

[zhengyaxin_8bit]

photobucket and imgur are some free places to put images.

photobucket and imgur can put other data except images？

Avoid RapidShare - it's so bad most folks call it RabidSwear. I have free accounts on both FileDen and MediaFire, and have reasonably good luck with the two.

This is FANTASTIC! Very good work!

Thank you very musch!
The Gen-debuger is writed by you?


I used it to watch some memory unit,and vdp's status etc, it's very usefull. But I think that somewhere will need improved. Can you
append more debuger function, "step into","step out","step over","set breakpoint for cpu address or R/W ram","set breakpoint for R/W vdp vrom,crom,scrollrom",

Now, The debug code is a difficult work for me,Have you a good way?

Yeah, I'm behind Gens KMod while Stef is behind Gens
I won't update it anymore.
We are all waiting for version of Medarin but it seems he doesn't work on it anymore

He does but he want a sort of multi system debugger (and so not only for Gens) so it takes sometime to design it.

The new features you're asking it is exactly what Medarin is working on

[djcouchycouch]

Has he ever given a roadmap as to when he'll release something?

Not really, i believe he does not have many free time but at least he seems really motived

I noticed you have trouble with having to draw too many lines I have wrote a program that draws the lines in real time on the genesis and displays it on the screen this avoids using the full screen bmp buffer and saves ram.

Code: Select all

#include <genesis.h>
//this demo demonstrates what is called a small bmp
//this is useful for if you just want to draw a line some were on the screen
//bmp_size is in tiles
//change bmp_size_x and bmp_size_y to set the size of the mini_bmp buffer

#define bmp_size_x 8
#define bmp_size_row bmp_size_x*4
#define bmp_size_y 8
#define bmp_size_y_pixel bmp_size_y*8
#define bmp_tiles_total bmp_size_x*bmp_size_y
#define bmp_size_bytes_total bmp_tiles_total*32
u8 bmp_buffer[bmp_size_bytes_total];
//bmp_begin_tile is determains were the bmp outputed tiles are stored in the vram
void set_two_pixel(u16 x,u16 y,u8 color)
{
    bmp_buffer[(y*bmp_size_row)+x]=color;
}
s16 abs_gen(s16 val)
{
    if (val < 0) val = -val;
    return val;
}

void draw_line(s16 x0,s16 y0,s16 x1,s16 y1,u8 color)
{
   //dx := abs(x1-x0)
   s16 dx=abs_gen(x1-x0);
   //dy := abs(y1-y0)
   s16 dy=abs_gen(y1-y0);
   s8 sx,sy;
   //if x0 < x1 then sx := 1 else sx := -1
   if (x0 < x1)
   {
     sx=1;
   }
   else
   {
    sx=-1;
   }
  // if y0 < y1 then sy := 1 else sy := -1
  if (y0 < y1)
  {
   sy=1;
  }
  else
  {
   sy=-1;
  }
   //err := dx-dy
   s16 err=dx-dy;
  // loop
  while (1)
  {
    // setPixel(x0,y0)
    set_two_pixel(x0,y0,color);
     //if x0 = x1 and y0 = y1 exit loop
     if (x0 == x1 && y0 == y1)
     {
      break;
     }
     //e2 := 2*err
     s16 e2=2*err;
    // if e2 > -dy then
    //if (e2 > -dy)
    if (e2 > -dy)
    {
      // err := err - dy
      err-=dy;
      // x0 := x0 + sx
      x0+=sx;
    }
     //end if
     //if e2 <  dx then
     if (e2 < dx)
     {
       //err := err + dx
       err+=dx;
       //y0 := y0 + sy
       y0+=sy;
     //end if
     }
  }
   //end loop
}
void bmp_clear()

Indeed!

zhengyaxin_8bit, is it a release or a "pirate" version of your version ?

or, perhaps, it is the first "commercial" release of a game with SGDK ?!
