I have finally uploaded new version of powersdl to Aminet and to my MorphUp repository (http://www.lehtoranta.net/morphup/index.pmi).

Main changes are:
- MorphOS 2 or MorphOS 1 with Update Pack #1 required
- Fixed corrupted graphics in LGeneral game (and maybe more)
- Fixed gfx problem in UAE
- Fixed other potential gfx problems
- Most SDL sublibraries are now AltiVec accelerated
- Updated powersdl_image.library to sdl_image 1.2.7
- Added smpeg.library

The Update Pack #1 for MorphOS 1 is required because SDL is now using new MorphOS 2 libraries. With those new libraries libraries are about 1MB smaller Enjoy!

Great Work... Thanks for the Update!!

hi!

thx for the new release!
unfortunatley i think i've already found a problem with it:
i wanted to try an sdl game quickly, the first one i started was x-pired - and it has corrputed gfx (ie. no gfx at all) and a bunch of cli errors: it cant load any of the .bmp gfx data. im sure that with psdl 12.1 this x-pired game worked.
other few games i've tried worked fine only this with the .bmp gfx has failed.
thought i let you know:)

Battle for Wesnoth has some GFX errors.

Can you post screenshot from Wesnoth gfx errors?

I am going to try x-pired tomorrow. You dont know any other game with similar problems?

On the right side of the Picture in the Menubar some gfx quircks.

Hi,


Just did a quick check with X-pired (as I think he ment my port).

Getting error messages when trying to load Windows Bitmap gfx.
JPEGs are OK.


Bye HAK

Itix : UAE now can runs on a 32 bit screen... but it's very slow. With a very old version of PowerSDL, we was capable to lunch UAE quite smoothly in 32 bit screen. Can you enabled 8 bit in SDL ? Or enabled 16 bit screen when we launch UAE from a 24/32 bit Ambient screen ?

I dont know if that is possible. Due to a bug in UAE screen handling I am forced to update screen more often than necessary. But maybe I have introduced new bottleneck in PSDL, I check this out later. However are you sure that it is just that old PSDL version which was faster and your config (gfx card, monitor) didnt change?

Quote:

I wrote about this to Drummond years ago but he never added an option to use 8bit screens. E-UAE does not specify bit depth for UAE screen and therefore SDL must choose default setting which is same as Ambient screen depth. If I changed default setting to 8bit then UAE would run at optimal speed but other SDL applications could stop working.

I probably add new setting to SDLPrefs to force 8bit screendepth for applications like UAE. Or maybe even application specific settings.

-> However are you sure that it is just that old PSDL version which was faster and your config (gfx card, monitor) didnt change?

Itix : can you upload somewhere the 11.x or 12.0 version of PSDL ? I will try and see which version is the faster in 32 bit screen with UAE.

Please remember to include updated SDL_gfx in 13.1... ;)

Thanks for update:
dosbox0.72 which crashed badly at start with previous powersdl version now works but is slow
http://brain.umcs.lublin.pl/~rzookol/download/dosbox.lha
(maybe i did something wrong during compilation)

but dosbox from aminet crashed and my game (written long time ago but never crashed until this version) crashes also
http://aminet.net/game/board/sdl_football.lha

There is a bug in sdl_image which is triggered by AltiVec optimisations in MorphOS. And only in MorphOS because PowerSDL aligns SW surfaces for AltiVec.

I uploaded powersdl_image.library V9.4 for testing:
http://www.lehtoranta.net/powersdl_image.lha

Problems with BMP graphics are now gone.

@Daff

I dont have old archives anymore... I will look if I got some backups somewhere but they are probably gone.

@CISC

I wont

@zukow

I tried your game here and it didnt crash. What is your system setup? Any chances to have a log?

Btw I see gfx corruption at bottom when I have won the game (blinking text which I can not read). Looks like another case where AltiVec alignment breaks SDL... (same with Wesnoth).

Pixel gfx sw works better than ever now !

(Have to mention that I have a G3)

I have G4 ad morphos 2.2
With http://www.lehtoranta.net/powersdl_image.lha my game runs ok (except that corupted gfx).

[ Edited by zukow on 2009/2/22 19:44 ]

I wonder if gfx corruption is coming from your game or from SDL. Are you using surface->pitch anywhere in your game? Poking or peeking into SW surfaces using surface->w as modulo?

Since this is 2nd game having problem with AltiVec alignment there is now small chance this problem is in PSDL. I really hope this problem is in SDL...

Quote:

Oh btw... is it slow always or just in fullscreen mode?

And how do you define slowness? It feels "ok" here. But then I dont use it very often.


[ Edited by itix on 2009/2/22 21:06 ]

i don't directly peek/poke into/form surface. Only plain SDL_BlitSurface

struct font load_font(char *name)
{
FILE *tmp;
struct font czcionka;
char nazwa_czcionki[32];

if((tmp=fopen(name, "r")))
{
fscanf(tmp,"%s %d %d %c %c",nazwa_czcionki, &czcionka.szer,&czcionka.wys, &czcionka.start, &czcionka.end);

czcionka.fontmap=SDL_DisplayFormat(IMG_Load(nazwa_czcionki));

SDL_SetColorKey(czcionka.fontmap,SDL_SRCCOLORKEY,czarny);

fclose(tmp);

}
else
puts("Blad z czcionka");

return czcionka;

}

inline void rys_char(SDL_Surface *bitmapa, struct font czcionka, int x, int y, char znak)
{
SDL_Rect from, to;

from.x=czcionka.szer*(znak-czcionka.start);
from.y=0;
from.h=czcionka.wys;
from.w=czcionka.szer;

to.x=x;
to.y=y;
to.h=czcionka.wys;
to.w=czcionka.szer;


SDL_BlitSurface(czcionka.fontmap,&from, bitmapa,&to);
SDL_UpdateRects(bitmapa,1,&to);

}

void napis(SDL_Surface *bitmapa, struct font czcionka, int x, int y, char *znaki)
{
for(; *znaki; *znaki++)
if(*znaki>=czcionka.start && *znaki<=czcionka.end)
{
rys_char(bitmapa,czcionka, x, y , *znaki);
x +=czcionka.szer;
}
else
if(*znaki==' ')
x +=czcionka.szer;

}

This font is small 8x8 (taken form RSI Demomaker), maybe to small for altivec

@zukow

Thanks a lot! I found another bug from BMP loader in sdl_image. It just does not handle surface->pitch correctly and fails if default align is not used.

Please try powersdl_image.lha (v9.5) again. Gfx corruption in SDL Football is gone.

@others

I am also interested to know if gfx corruption in Wesnoth is gone. I dont have it installed atm.


[ Edited by itix on 2009/2/23 8:22 ]

wesnoth is ok for me, but x-pired still cant load the bmp gfx...
havent tried that football game yet.

edit: tried football, it started but stopped coz it was unable to find a server.. menu was ok:)

[ Edited by sadddam on 2009/2/23 2:22 ]

There are still the same GFX coruption in window and fullscreen mode.
Like on the picture i uploaded.

[ Edited by ThePlayer on 2009/2/23 18:53 ]

@ThePlayer & sadddam

That sucks. So some users are getting gfx corruption in Wesnoth and some users not. You both are probably using 32bit screenmode, right?
