I'm sure there are plenty of calculators out there for the PSP, but this is an EBOOT, not a LUA script.
The forums wouldn't let me upload my zip; it keeps saying that it exceeds the maximum space even though it is only about 274 KB and the zip limit is 9.4 MB. (Maybe because the archive contains .png graphics?) So the link: http://s15.quicksharing.com/v/989507...eCalc.zip.html
This app is nothing but a simple calculator for doing math operations (+,-,/,*) on floating point numbers. I have tried to make the input system as similar to a real basic calculator as possible. Btw, this is my first release of a homebrew. I'm working on a simple little pong-like game but it's not quite ready yet.
I would release the source but it is too messy and there is no point in doing that yet. I would like to help the PSP homebrew community in whatever small ways I can.
