Which source file increases the actual size of an emulator.

I tried my hand at the Handy (Lynx emulator) and boy that thing is small. It's hard to even play the emu with both eyes open.

If by "actual size" you mean the screen size, as you seem to, then click the options menu and select "4x screen zoom" or one of the full-screen modes. Press alt-enter to exit full-screen. I don't know what you mean about source files.

Oh silly me. I didn't even think of that.

By source files, I'm talking about the c++ files. I've done a little work in it before but not with emulators.
