This file is a modified version of 1.25-103 as all others on the internet have corrupt *.bas and gwbasic.exe files. They have been removed in this version. The floppy image will boot in dosbox and virtual box (haven't tried others, but is not readable using Winimage as it uses a very early dos floppy format.
