How to improve performance of Mame on the Acer Aspire One
In this post I described the process for installing the Linux version of MAME (XMame) on the Acer Aspire One.
There are a couple of settings which can be changed to significantly improve the performance of XMAME and make the games run at full speed.
To make these changes:
- Load GXMame ( the front end for XMAME) from the advanced menu.
- Go to the option menu.
- Choose Default Options.
- Click the Display tab.
- In the Resolution section – set Height scale and Width scale to 2

- Click the Rendering tab.
- In the Video Mode Menu box select the XVideo option.
- Make sure the full screen option is turned off.

- you won’t to able to see the OK button on screen so press the Alt and o keys to save your settings.
When you play your games now they should run at good speed.
