ONScripter play online

ONScripter (O-N-Scripter) is a program that interprets a script written for NScripter in its own way.

You need to prepare game data separately.
Then, you need to create folders for each game under /sdcard/ons and place game data (nscript.dat, etc.) under those folders.
You also need to place a truetype font file named as default.ttf in the same location as game data.
If you want to play video, install an appropriate video player such as MX Player.
