to use the ide you have to go to the option menu and put in the path for your tile editor and emulator (i use sgtd tile editor and GENS emulator) after that go to the compiler option and check mark copy output file to project directory and rename so it shows up in the folder, then check mark after compilation run in emulator. After that go to target option and pick a output type (cart,sega cd,32x cart) hit apply then start coding
