Hello.

I'm using Retropie on my Raspberry PI 2 for Retrogaming. It works, exept for 2 Games..... Gunship 2000 (i posted already) and GTA.
With GTA i can only use the 8-Bit (GTA8) Version, the 24 Bit crashes. Thats no deal, the 8Bit is ok for me.
But that Version runs quite slow. I know GTA as a fun and quite fast game, but it runs pretty slow, but playable.
If you steal a car, in looks like in slowmotion, and the cars dont go fast 😉.

If GTA can't be faster on the Raspberry Pi, it would be a pitty ;(

Can someone tell me which conf for Dosbox works best?
I tried around a bit with the cycles and the core (fixed cycles / auto / dynamic etc.)
I'm pretty unsure what grafik card i should use.... I tried oldvbe now....

I enclosed my config file....

best regards

I suggest you, use Dosbox-x sdl1 + opengl, and GTA 3DFX that works very fine for me

Cycles = 16384
Core = Dynamic
Machine = svga_s3
Scaler = None

I recommend manual compilation of latest dosbox-x version , optimizing for that hardware with commands like :

export {C,CXX}FLAGS='-O2 -fPIC -march=native -mtune=native -pipe' ; \
export OPTFLAGS='-O2 -fPIC -march=native -mtune=native -pipe ; \
CFLAGS='-O2 -fPIC -march=native -mtune=native -pipe' ; \
CXXFLAGS='-O2 -fPIC -march=native -mtune=native -pipe' ; \
OPTFLAGS='-O2 -fPIC -march=native -mtune=native -pipe
