Dear Abandonia visitors: We are a small team that runs one of the largest DOS Games websites in the world. We have only 3 members of staff, but serve 450,000 users and have outgoing costs like any other top site for example: our servers, power, rent, programs, and staff. Abandonia is something special. It is a library of old games for you to download. It is like an old gaming arcade with all the old games in their original format. Abandonia is a place where you can find great old games and have fun four hours and years. To protect our independence, we are dependent of our friends using the site. We run on donations averaging around 6 USD (5 Euro). If everyone reading this gave the price of a cup of coffee, our fundraiser would be made easier. If Abandonia is useful to you, take one minute to keep it online for another year. Please help us forget fundraising and get back to Abandonia.

When Abandonia was founded it was to collect and present all old games where the copyright protection had been abandoned, hence the term ’abandonware’ and the site name Abandonia.com. We are still doing our best to keep the site open and free and will appreciate your support to help it stay that way.

‐ Thank you from the Abandonia Team

We are trying to make it easy for people in every country to donate. Please let us know how we could make it easier for you.

Please give whatever you can to help us.

Optimizing Performance

Submitted by admin on 28. March 2008 - 13:06.

Some games will run too slow, so you will have to adjust cycle count and frameskip. Do this by using next key combination:

CTRL-F7 = Decreases frameskip
CTRL-F8 = Increases frameskip
CTRL-F11 = Slows down the game
CTRL-F12 = Speeds up the game

You can see current cycle and frameskip at the top of DOSBox window. (Only in windowed more, so if you are in Full Screen, change back to windowed mode by pressing ALT + Enter)

Cycles and Frameskip

By default cycles are set to 3000 and frameskip is set to 0.

NOTE: Default values for cycles and frameskip can be changed, as well the rate by which they change. This will be included in advanced topics.

If you speeding up the game, you have to watch over your CPU usage (Press "ctrl + alt + del" on your computer and select "Performance" tab on WindowsXP) as if CPU usage reaches 100% game will again slow down

CPU Usage

Some games on the other hand will run too fast on the new machines, and then you must slow your computer down until you can play the game normally.

This will cover basic installation and use of DOSBox. Next tutorials will be on use of DOSBox front end "DFend" and advanced configuration set-up. (and use of predefined shortcuts)
