maybe you could help me out about creating/editing .img files
i do have a dosbox daun running win95 ... in the mounting section as follows :

lgdfxrom 86c764x1.bin
imgmount 2 250.img -size 512,63,16,520 -t hdd -fs none
imgmount 3 1875.img -size 512,63,64,952 -t hdd -fs none
boot -l c

in the 2nd IMG file theres a ISO (cd image) file inside .... can you somehow replace that ISO w/ another random .iso cd image? or do you need create a whole new .img file ?
anybody know which tool to use best and how to get it to work under dosbox daun ?
