The language BasiEgaXorz uses is not like Visual Basic, and it certianly wasn't derived from it. Today, when most programmers think of the BASIC language, they think about Visual Basic. The compiler will also compile CD ISOs for the Sega CD attachment, ROMs that can use the features of the 32x extension, and not to mention, creating ROMs for the regular console without attachements. That means, by using this compiler, you can program in a form of BASIC language to create awesome programs, or games for your old Sega Genesis game console.
Simple, BasiEgaXorz is a BASIC compiler for the Sega Genesis consoles.
