V1.5: Now reads engine.ini and ers.ini to check for torque curve name (if different than torque.lut and kers_torque.lut), additional icons available when creating a child car, handbrake editing, error check button (in testing, for now only checks automatic_gearbox profile, will add more later if requested)
New update, now allows to create a "child" from an existing car to avoid editing existing cars, some code update.
Open to suggestions and bug reports!
Edit: next upgrade will get icon selection and ui.json editing
V1.2: Allow decompressing data.acd (thanks to quickbms). Quickbms is distributed with the file and must be left in the same directory as the excel workbook (distribution is allowed by his creator, readme included!)
Fixed a small bug with the tweaker, added ability to manually edit data files.
To do: allow reading of compressed data files (probably in next release)
