[Request] gpSP GameBoy Advance Emulator - Page 20 - maemo.org

luiscesjr | # 191 | 2010-12-14, 15:24 | Report

So, now my triple posting =)
got it to work, was doing something REALLY stupid.
Anyway, it seems to be slower than vgba, you will see on my screenshot.
Needs some tweeking, but about this, as I said before, I can only start next week.

I will try to upload a video, but I don't have an extra camera with me now, but my webcam from the notebook may do the work.
Oh, and most important, was forgetting, that half fullspeed I got at
600 mhz. At 950 mhz I get 45-55 fps. ( At the same screen I uploaded the image )
At the end Javis was right! We didn't get that much improvement at speed.
Althought we need some little big work on this, I guess it will be a good emu...
Cheers
Edit.: Without sound and frameskip 5 I get a great and nice fullspeed ( 950 mhz )

You doubted that? I was running it when I was posting that

On the positive side ignore the fact that it does not fill the screen. As it is using HAA you can do any scaling you want without losing performance (because there's a constant performance hit that the game is already assuming).

Never! how could I doubt Javispedro! Haha
Anyway, I vomited again some wrong stuff, HAA is not the SDL_haa right? I found that part around some code from some file in this project. ( don't remember which one )
Edit.:

If anyone is interested in trying the emulator, it's quite simple to get it to work, anyone doesn't know how to use it, just ask
and I will explain, but it won't be much good right now.
As savegame and savestate doesn't seem to be working properly...

luiscesjr, I don't know if this helps or not, but summeli has done a gpsp port for symbian with Qt. Maybe he can help somehow?

Thanks Acidspunk, I will try contacting him and see what we can get together.
Oh, and could you tell me how " unplayable " was mario kart on vgba?
I never tried this rom there.
I was giving a look on the past comments, people were concerned about sound, if someone didn't use the emu yet, sound is choppy,
not as much as in N64 emu so it's " listenable ".

So well, another EDIT.:

Got the save to work.: ( Some more screenshots)

I Asked for a long time how to install the gba.rar posted on page "i-don't-remember-the-numb"
So pleaaase if you could explain how to install and test this it would be very cool from you.

Or maybe you can wait to release a descent version.

EditV4, Updated

I guess no one will have trouble with that, it's not really that hard.
I will explain then, as save worked now for me.
My main problem was that I was only doing chmod on the executable itself, dumb from me.
So what you will do is download Figa's release, and take his gba folder only, forget about the rest, it's only code.
Before everything, you MUST put a gba bios file on the gba
folder.
Transfer it to MyDocs
( If you are using Filebox, or ssh just copy the folder to home/user/
as well as copying the libsprig.a to /usr/lib/, so
you can skip the first code, still must chmod after)

Open xterminal and do.:

Code:

mv /home/user/MyDocs/gba/libsprig.a /usr/lib/
mv /home/user/MyDocs/gba /home/user/

Then : ( Make sure to have devel repo enable )

Code:

root 
apt-get install libsdl-haa1.2-dev 
cp /home/user/gba/gp bin/
chmod a+x /home/user/gba

( Also Javispedro pointed out that installing DrNokSnes
from extras-devel should install also the libsdl-haa1.2-dev,
so if you have his Snes emulator already installed from
devel repository, you may skip apt-get libsdl-haa1.2-dev )

Close xterminal, or restart it, whatever, just no need to open
gpsp as root.

Code:

cd /home/user/gba 
gp

You will enter the initial gui of gpsp.

Before using it, you must know the keys.:

Z = A button
A = B button
S and X = L and R buttons ( not sure which )
Q = Select button
W = Start button

To go to your rom directory you will notice two small white dots
on the initial gui, just go with the directional keys to it, probably
only click right on the directional, and you will highlight it.
Click with the Z button, and you will be able to " surf " around your
directories.
Select the rom and while playing it, you can enter the Gui again
and do whatever you wish by pressing backspace ( if I am not
mistaken ).
Some games work better on some configs, like DBZ Buu's fury work better with manual frameskipping 5, but pokemon
work better with auto frameskip and set to 1.
Hope I did not forget anything!
See if it works for you...

Remeber this is Figa's work! If then I make some optmizations to
gui and/or speed, doesn't matter it's still his project and credits to him!

Well, it can actually be played. No graphical glitches or anything, but it's too slow and choppy to be enjoyable, in my opinion.

HAA is SDL_haa, was there any problem?

For now none. I just found other HAA libraries, and then it made me wonder

but no confusion now.

I didn't play it before on vgba, but on gpsp is enjoyable I think...
Sound isn't much of a improvement maybe, but can't really compare!

Some of you may still encounter permission denied while trying to
execute gp, just

Code:

chmod 777 /bin/gp

Guess the permission denied is because you can only copy them as root...
I may be wrong though.

Now, about button config, you should edit the conf.gpsp
file, you will notice some numbers there meaning the keyboard buttons,
you must change those.

Cheers
