From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What it is

From duckduckgo:

"DOSBox Pure Unleashed is a standalone, free, and open-source emulator for desktop platforms (Windows, macOS, and Linux) designed to simplify the experience of playing classic MS-DOS games. Developed by Psyraven and released under the GNU General Public License, it serves as a user-friendly fork of the original DOSBox, originally evolving from a core used in RetroArch."

Due to significant performance improvements over X11, a more aggressive CPU/GPU usage compared to its "vanilla" version. Note: You'll have to lower CPU cycles and overall performance if you are on a beefy PC -- this has been made with the "potato PC" (read: raspberry pizero) in mind. Which means, it'll crank both CPU and GPU usage all the way (possible) to the top.

The required dependencies are: "sudo apt install
build-essential
g++
make
libsdl2-dev
libgl1-mesa-dev
libasound2-dev
libpulse-dev
libwayland-dev
libxkbcommon-dev
libegl1-mesa-dev
libgles2-mesa-dev" if you are on debian.

One-time config after extract:

cp ZillaLib/Linux/ZillaAppLocalConfig.mk.example
ZillaLib/Linux/ZillaAppLocalConfig.mk

Then edit "ZillaAppLocalConfig.mk" accordingly (should be self-explanatory):

EXTERNAL_SDL2_INCLUDE = /usr/include/SDL2

EXTERNAL_SDL2_SO = /usr/lib/x86_64-linux-gnu/libSDL2.so

(use aarch64-linux-gnu on ARM64)

How to compile:

Extract the tarball. Then,

cd dosbox-pure-unleashed

make linux-release -j$(nproc)

After the compilation is complete,

export SDL_VIDEODRIVER=wayland ./Release-linux/DOSBoxPure_*

How to install

Simply copy the built binary to /usr/local/bin/. or to any directory you'd like.

Notes

I've tested this on a orange pi 5 max and everything works as intended. The results may differ on your PC, so keep that in mind.
