M.A.M.E. 0.61 SDL [DEV] - Beta3.3

[FranceMSR]

Beta3.0 available

Totally changed frameskipping logic with awesome improvement on execution speed on Raspberry Pi v0 and v1. Now when emulator is closed these information are shown:

Display Width: 1920
Display Height: 1080

Nominal FPS: 60.000000
Virtual FPS: 60.331492
Real FPS: 59.889503

Displayed frames: 271
Skipped frames: 2

Total play time: 4.525000 seconds

Real FPS refers to FPS shown, if this value is the same or near Nominal FPS emulation performance will be the same of original hardware. Now pay attention, this is the great news: Virtual FPS refers to cycles per second of game main loop, so input, sound, video and so on. If this value is the same or near Nominal FPS emulation performance that user feels will be the same of original hardware though Real FPS is not the same as Nominal FPS.

As a proof , here a comparison video (in italian but you should see the video!!!) between execution on development laptop and Raspberry Pi v1:

Let me know ;-)

Ok it is clear that nobody here is interested and I don't want to waste my time anymore

@FranceMSR i am pretty sure no one here wants to be discrespectful!
Your project is cool, but it seems that the majority of the Pi-Users here concentrate on Pi3 and Pi4.
I guess the one who creates an optimized MAME-Port, based on a current MAME, for the Pi3/4, which runs all the games that still stutter, or dont run at all, would be the Hero of the Month :)

[dankcushions]

without source code and a corresponding build script it's unlikely to get much traction here, IMO. i think it's a cool idea so i hope you reconsider.

Available Beta3.3.

Framebuffer dimensions, scanlines, HD artworks and more. If you're interested I'm here

Maybe you don't understand that a porting that is very impressive compared to lr-mame2003 from the point of view of speed has its good behaviour and improvements also on Raspberry Pi v3 and v4.

lr-mame2003 doesn't have the possibility to use HD artworks, my porting does

You only have to add the system to es_systems.cfg

<system>
    <name>mamesdl</name>
    <fullname>MAME SDL</fullname>
    <path>/home/pi/RetroPie/roms/mamesdl</path>
    <extension>.zip .ZIP</extension>
    <command>cd /home/pi/MAMESDL; ./mame_rpi4 -rompath /home/pi/RetroPie/roms/mamesdl %ROM%</command>
    <platform>mamesdl</platform>
    <theme>mame</theme>
</system>

Change /home/pi/MAMESDL (contains the binary) and rompath (contains romset) accordingly with whatever you want

I'll likely try to make a scriptmodule for building this soon.

I modified the M.A.M.E. code in order to use high definition artwork. My format is .lyt and basically you have to insert artwork image with .png format in artwork folder with the same name of the romset (i.e. for Final Fight "ffight.png") and a text file with the same name and .lyt extension with a simple code like this inside:

Width="4000" Height="3743"
HoleWidth="2920" HoleHeight="2190"
HoleX="540" HoleY="822"

From a packaging/scriptmodule perspective, this doesn't change anything for me, but that's really cool.

The current SDL Image library available on Raspbian is an old version that use an old libpng version with a bug. In order to use HD artwork you need to compile libpng and SDL Image from source and in sequence.

So, download these archives, libpng-libpng16.zip and SDL2_image-2.0.5.zip, and copy them in

/home/pi

then run these commands from terminal:

LIBPNG

unzip libpng-libpng16.zip
cd libpng-libpng16/
./configure
make
sudo make install
sudo ldconfig

SDL IMAGE

unzip SDL2_image-2.0.5.zip
cd SDL2_image-2.0.5/
mkdir build
cd build
../configure
make -j3
sudo make install
sudo ldconfig
