Incorrect rendering of loading/intro image in some games

[polpettedorso]

Some of these games (e.g. Banshee, Hollywood Poker Pro, Bloody Money...) don't display correctely: please take a look at the attached picture.
This happen when installing via code, but it is ok via binary installation

@polpettedorso
Thanks for the report.

This is related to the latest updates I made in the dev version, where I merged in some code from WinUAE. It included blitter and drawing functions, and those I suspect caused this effect.

I'll look into it and fix it.

Hi! I do confirm this behaviour also with Alien Breed2, Dungeon Master 2, Roadkill/CD32, Robocop2, Uridium2.

@polpettedorso
Did you test this in the dev branch version or the master one?

I can't recreate it with the current dev which has the latest updates from WinUAE.

[polpettedorso]

I just updated form source and the bug is still there... :-(

Same bug i had on the iPad. But i never fixed it.
It has to do with the color rendering of the HAM Mode.

Pelare note that in the stable version the bug does not occur

@polpettedorso
OK, so does this happen only on HAM screens? How about HAM screens from Workbench, showing images?
In my version of Banshee, I didn't see the problem - unless there's another version that you tested with (e.g. CD32?)

Maybe I can recreate it with another title then, we'll see.

[polpettedorso]

I Think it's only with ham screens.
I tried also with "links" (the golf game) whose menu are ham and it is all buggy

[CypherXG]

I tried many Games like Blood Money or Demos.
It make no difference if they start from WHDLoad or direct from ADF File.
Also it make no difference if you are changing between OCS, ECS or AGA or changing the Chipset.
Best is to find out if you use a Paint Programm like Dpaint which can select a HAM Screenmode.
Here a Screenshot from Stryx:

Here from Bloodmoney

Or from Hollywood Poker Slideshow
Mmhhh in the Slideshow it look like that the Red color is missing or incorrect shown:

I hope i can help you with this informations...

Pelare note that in the stable version the bug does not occur

In the stable Version the GFX Render Code was not changed.
After that the Statusbar was incorrect shown in 16bit RTG mode or in some Amiga Screenmodes.
The Scanlinebug is there and the wrong color mode.
I think something is wrong with the drawing or amiberrygfx code.
The picasso code seems to be ok, because RTG Render works and the errors are also shown if you don't usw WHD Load mit RTG in the backround.

@CypherXG
Thanks, I think I know what caused this then.
I'll work on fixing it these days and update the dev branch accordingly, after testing it.

[midwan]

This is now fixed, at least according to the tests I made with the samples mentioned above.
If you find another issue with HAM modes, please let me know.

[polpettedorso]

Hi! I tested after updating form source, bug nothing changed. Am I doping something wrong?

[midwan]

@polpettedorso
Are you sure you got the dev branch?

[CypherXG]

Dev branch is fixed. Working perfectly.
You have to replace only your drawing.cpp. That's all.

Nice work. Midwan.

[polpettedorso]

Sorry to bother you again: I'm a newbie and not a programmer, but I'd like to contribute at least testing.
Via putty I gave the following instructions:

cd ~
git clone -b dev https://github.com/midwan/amiberry.git  
cd amiberry

then

make all
I come back to retropie, but there was still the old version of amiberry. Then I tried to update from source, but I think it installed the master version.

I'm sure I'm doing something wrong, but I couldn't figure out what.
Could you please help me?

thanks

[polpettedorso]

Nevermind my request, i found this: https://github.com/midwan/amiberry/wiki/Compiling-Development-Branch and I did it.
Amiberry works great. I will keep on testing the new developments.
Thanks for the great work
