I am very interested in getting this to work, but the engine gives me problems with the "str_for_int" it says undeclared identifier. There isn't anything in the manual.
The "SHOW" and "WWRAP" flags apparently don't work also (when I commented out the str line. I changed show to visible and it worked, but I don't know what to do with the wwrap so commenting it out seemed to work. (using a7)
Any ideas?
