DOSBox Port

From NikiWiki

This page will help to organize the port of DOSBox to OS/2. Initially, Martin Klingenfuss offered to pay the first person that ported DOSBox to OS/2 500 EUR. He also invited other people to join in and donate some money. To organize and coordinate all activities arround the port, this page was created.

Porting DOSBox to OS/2 is currently NOT a netlabs.org project! (no project homepage, no CVS,...) However, since netlabs.org offers this great WIKI, we decided to host the page here, so everybody can contribute to the content of the page easily.

This whole thing was started here (german!): http://www.os2.de/forum/diskussion/index.php3?all=87595

What is DOSBox?

Homepage of DOSBox


Why port DOSBox to OS/2, don't we have a Virtual DOS Machine?

" DOSBox is a DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X...

DOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem/XMS/EMS, Tandy/Hercules/CGA/EGA/VGA/VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games...

You can "re-live" the good old days with the help of DOSBox, it can run plenty of the old classics that don't run on your new computer!

DOSBox is totally free of charge and OpenSource."


Addon from Martin Klingenfuss:

As a DOS-games-player I think it would be great to have the virtualised DOS-box under OS/2 for usage of seamless SVGA-graphics under PM and sound via MMPM so modern PCI-audiocard will play DOS-games sounds.

Maybe its nesecery to work on the multimedia/graphicinterfaces under OS/2 to make the DOS-Box run with same quality as under Win32. Because I am no programmer, I do not know what is exactly needed for this portation.

About the Money

What needs to be done to receive the money

The money will be payed to the first person or group that successfully ports DOSBox to OS/2. A full OS/2 port has to satisfy the following requirements:

  • Version 0.63 or above of DOSBox must be ported
  • Exactly the same features as on Windows
  • Quality of gameplay is exactly the same as on Windows, yes, you can port the bugs too! ;)
  • ODIN must not be used
  • Source code, compile requirements and compile instructions have to be available from a public place
  • if changes to the DOSBox source are required, they must be documented

The money will be paid AFTER the port is done and tested by a few people.

How much money will be paid

Since the first large amount of money was donated in EUR, we use EUR as the currency here. If you need to convert your currency into EUR, you can use the Bloomberg Currency Calculator.

If you want to donate some money, please add yourself to the list above and contact Martin Klingenfuss (info AT expert-services DOT de)! Martin will tell you when and how to transfer the money. If you want to contribute anonymously, that can be arranged as well.

People who want to sponsor the project should donate at least EUR 20 to make it worthwhile. Martin guarantees a refund in case the project should fail.
