Wow. That is the single worst barrage of advertising I've seen in the history of the internet. I can't imagine what it would be like for those poor shmucks running 5 year old copies of IE with no pop-up blocker.

Anyway, hosting aside...

I'm running TGEmu right now, not the best emulator ever made, and I see a static image of fire. Is it supposed to move? Not that I'm complaining. I can't even code "Hello World" on a PCE.

For emulator, i don't know tgemu, but try with mednafen  :wink:

It works in Magic Engine, looks pretty cool as well. You could probably use a similar routine to simulate water I imagine.

(And for the love of god, please upload to somewhere like rapidshare next time!)

Yes i have used a tom's hsync routine used for a sgx demo (in colaboration with xavier).

The demo have a wavy hsync deformation of background.
I have used that with my fire background, without wave data, the deformation is randomised,and very fast.  8)
This give you an illusion of fire  :mrgreen:

Thanks tom for your hsync routine  :clap:

OK, I tried it in Magic Engine. Looks great!

Looks pretty nice.  It'd look great in the background of the first level of Dracula X.

 Wow, that's old. This one's faster, slimmer, but no SGX support. http://75.126.152.9/~pcengine//huc_stuff/hsync.zip


 Dude, that fire demo is awesome! Hahaha :D Nice

Thanks tom for latest version  :mrgreen: ..

Eh tom the huc function to set bgnd color to 0 is ..

set_color(0,0); 

nothing is more easy  :mrgreen:

Tom ,if i use your hsync routine ,in first time for make a background x_scroll, the scrolling is flicking !!  :shock:

But a background y_scroll is normal ..


Bug removed, it turn more faster in C LOOL , :-"

this

Code: [Select]

    temp=map_x+scroll_x1;

#asm
lda _temp+1 ;// This is over a hunderd times faster
ldy _temp
lsr a
say
ror a
cly
sta _hs_x_l,y
sta _hs_x_h,y
#endasm

replaced by

Code: [Select]

temp=map_x+scroll_x1;
    hs_x_l[0]=temp>>1; /* A little fixed/float point variable */
    hs_x_h[0]=temp>>9;
    temp=map_y+scroll_y1;
    hs_y_l[0]=temp>>1;
    hs_y_h[0]=temp>>9;

finaly i have replaced by

Code: [Select]

#asm
    cly
    lda _temp
    sta _hs_x_l,y
    lda _temp+1
    sta _hs_x_h,y   
#endasm
it seems that your code is a 2 divider .
For exemple, if i have 10 in temp,both hs_x_h and hs_x_l have 5 ..
probably not the best way, but it works.

Heh, I must have messed with the source example a few times. That one part is a 15bit:1bit fixed point number. That's why there's a 16bit shift there (A:Y).

Strange, because it works fine with your exemple, but very bad with a classic bgnd ..

And re strange, y_scroll works good with same code ..

BTW, is it possible to use your hsync routine like huc scroll function ???
I have tried to make it, but all my bcgnd is duplicated in x_scroll, not a part of it.
