Idea
Create a package of code compiler for the emulator, which took up little space, and will as portable as possible, it will not require installation, and which can be stored on a USB flash drive. Current Status: semi-done (works with almost emulator, except rAthena for reasons inside CMakeList.txt and other broken parts in code)
Download Link: MEGA or Google Drive (189MB)
How to use?
Like on Linux, but on windows (thx to Cygwin)
Download, extract, run start_console.
