We’re trying to figure out how many different versions of groovie games (particularly t7g) there are, and the differences between them. If you want to help out, you’ll need a copy of t7g (or other Groovie game), the ability to create an iso file from it (e.g. one of these pieces of software: http://en.wikipedia.org/wiki/List_of_ISO_image_software), and the ability to generate md5 hashes from the resulting files. Then post the relevant information as a comment on the checksums page. We will also need the executable version number: this can be found by running the executable (v.exe for t7g, v32.exe for 11h) in a command window (or in Dosbox).
