There are two files in the download folder for ping pong. The one is an image background and the other is the main game and intro.
I have been able to increase the speed enough that it is fast enough to be tolerable for a 30mhz machine. However for faster true MS-DOS hardwares the game speed increases accordingly.
This can be played in DOSBox 0.74 or compatible with varying cycles depending on your preferences. Just please keep in mind that higher DOSBox 0.74 and compatibles are not true hardwares but merely indicates the potential of a faster hardware. So if you have a 133mhz hardware the game plays faster.
You also need both files for the game to run successfully!
Thank you.
