I made this little app a while ago to play a sprite strip, it's pretty limited (bmp only, single strip) though and doesn't export, when you click open file the top textbox is the sprite strip name and the bottom is the number of frames (which it works out the width of each frame from, it's not width because it's easier to just count the number of frames by eye). Also textbox caret controls: u,d,l,r,home,end,tab,del & backspace (because a friend didn't even realize you could edit the text
)
