from MrX256:

This is the second version of my IPv4 calculator app for PSP. The new version now uses Intrafont for the fonts instead of the default LUA font. Converts Internet Protocol version 4 addresses and subnets to binary form and back to IPv4 form.

This app is coded in LUA for LUAPLAYER HM 8.1, and comes bundled with it for easy installation.

Installation:

Copy "IP_CALC" folder to your GAME folder.
Example: ms0:/PSP/GAME/

Run the application from the XMB.
