May have issues running under Windows 10.Saving/loading tilesets in progress for editing.Using RPG Maker XP tilesets in RPG Maker VX Ace mode.Creating/modifying RPG Maker VX Ace tilesets.Creating/modifying RPG Maker MV tilesets.It can also take custom tileset pieces and help integrate them into completed tilesets. The RPG Maker Tileset Builder is designed to help people arrange the tilesets that came with RPG Maker into tilesets that better suit their game. I will need feedback to determine if this issue still exists. Note: The old program had issues running on Windows 10 system that are not used for applications development. New version! Fixes an issue where A3 tilesets could not be saved.
