I've got a project that was written in BASIC. I'm not sure of the exact reason, but the app will not function except when being run from a FAT-16 file system.
I'd rather try to set up an environment that will support this app in a modern OS (Vista/XP) instead of rewriting it.
Does anyone know how to get an app like this running in XP/Vista through some kind of code change (to the BASIC code) or FAT-16 "emulator" (if such a thing exists)?
You may try running it via a DOSBOX:
DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, joystick, modem, etc., necessary for running many old MS-DOS applications that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows XP, Windows Vista, Linux and FreeBSD
(from their Wiki)
I use it for several years now. It is good, stable and quite robust. It has several third-party GUIs as well, to make your life easier.
