tilp_and_gfm VS tilp_and_gfm

There are various cross-platform ways, I'm surprised you haven't found them (although ticalc.org probably doesn't have updated info so I guess that could explain it): TiLP (see my fork herefor Mac binaries directly) has a rom-dumping feature which produces a *full rom dump, and CEmu's dumper (which dumps less things but enough to emulate the calc, on which you can transfer missing things if needed, like apps). Since you're I retested in emulation you might want to go with CEmu (take the nightly build not the release) and follow the steps.

Google "tilp" and open the first non-ad result (it should take you to http://lpg.ticalc.org/prj_tilp/)

Try using http://lpg.ticalc.org/prj_tilp/ Tilp - I used that when I didn't have access to the student software. I was able to install apps and stuff.

Try tilp instead. It may give you a useful error if something goes wrong http://lpg.ticalc.org/prj_tilp/

Now that you've installed both TILP and TINCLS side by side, performing the extra steps described in the TILP README ( https://github.com/debrouxl/tilp_and_gfm/blob/master/tilp/trunk/README.win32 ), namely installing the filter driver and using Zadig, may help straightening up the connectivity between your computer and your calculator. The other computer OS don't need drivers for TI graphing calculators, which saves a lot of hassle for users.
