Is it possible to make civs trainable with just tblpad?
No. You need a button editor to make them trainable. Using just TBLPad will only change the strings. That is all it can do, and all that it will do.
yes DoA's right~! Tbl is just showed word that what a name,explain word of units and allow hotkey settings
Is memgraft the only thing that can edit the buttons?
yes that is work with Mem/Stargraft for the present
Ok what files show the buttons?
showed button image is cmdicons.grp if want custom button images for that unit, then just edit extracted bmp files and recompile grp then show changed button's image
