FastDOSBox

[hacha-dorada]

I become aware of the problems related to x86 emulation on the Pi when planning to test DOSBox with GUS emulation on my RetroPie. Looking around I found that some people tried to improve DOSBox funcionality for the Pi.

According to reports and the developers:
“FastDosbox is an enhanced fork of Dosbox, highly optimised for Raspberry Pi.”

Key Features
Speed of a 386DX @ 25Mhz thanks to dynrec x86 emulation
1080p native resolution,splendid upscaling using dispmanx (GPU aided)
Based on the sources Dosbox SVN and Dosbox 0.74
Between 200% to 250% the speed of Raspbian dosbox v 0.74
Console only, no support for X11
Can Run Microsoft Windows 3.x

While getting it from the Pi Store costs around $2.50, the source files can be got for free at the website.
I don’t know how to compile it and make it into ES, but I guess there are many gus around here who could help with this, and who knows maybe finally get it into the script.

I am having a look into this right now …

Great! Thanks for having a look at it. We’ll see how well it works as compared to the current emulator.

It compiled fine and it also started. I did not do more testing, so please feel free to give feedback!

You can install FastDosbox by updating your installation with the RetroPie-Setup Script.

Excellent job. I will give it a try.
Should I then update the script and install it from the sources?

[petrockblog]

You can either use the function of the RetroPie-Setup Script for updating the binaries or you can use the source-based installation to compile FastDosbox on your own. The binaries-based update should be faster, though.

I went into the Retropi_setup.sh and updated the retropi setup script but i do not see an option in the source based installation options. any thoughts?

[petrockblog]

fastdosbox is removed and replaced with dosbox (which is actually faster than our previously compiled fastdosbox)

with standard dosbox , retroarch dosbox.sh changes the following

sed -i ‘s/C_TARGETCPU.*/C_TARGETCPU ARMV4LE/g’ config.h

For raspberry pi 2 compiles ARMV7LE should give a significant performance boost

just FYI it was updated a few days ago to include armv7 optimisation.

Please use the github bugtracker for stuff like this, or even better a pull request ;-)

Yep long overdue i started using github properly. Anyways thanks for implementing my forum-based suggestions this week! DOSBOX running really nicely on pi2 now
