The ORE Video Driver uses the same 8x8 2bpp type of graphics also used by the Gameboy, so adapting the output from this program is pretty straightforward. (Thanks to Alex Schafer)Double click on GBTD and open the file. (You can accomplish the same thing by simply dragging the OREFont.grb icon onto the GBTD icon.)Take a look at "image1" Notice the numbernear the character I've scrolled GBTD to? This would be the same "character numer" used at the end of thecommand.To display an A, we would have used:TEXT.POKECHAR(10,3,WHITE,BLUE,RED,Also notice the numbered colors at the bottom of the window. These colors are the four colors we select in our program. While the colors used in Gameboy Tile Designer are actually selected by our POKECHAR command, you can see their relationships in the characters while in the editor. We are limited to the colors provided by the program while in the editor, but when we call them in our program we can use any color we please.Let’s make some changes to our HELLO program.Scroll down to character 69, the uppercase E and make some changes to it with GBTD.Select your working color by click on it at the bottom of the window, clicking each of the cells to change its color.Now, click on File, and Save recording these changes to the OREFont.grb file.Now minimize the GBTD program and double click on a file called:(Makefont is a simple batch file which calls on the Graphicconvert program to create a new OREFont.spin from your changes. You should see a small, black window appear for a moment, and then disappear. At this point, you have created a new ORE compatible font based on your changes.)Ready to see your work of art?Close any other files you have open in Propeller Tool and open theprogram again. Use F11 to send the program to the Propeller once again. This time you should see HELLO with your glorious new E character on the screen!The GBTD has several handy features for editing your graphics. You can shift, or flip your character with the small buttons on the left. You can also change your view to edit more than one character at a time. By clicking on View and Tile Size, you create largercharacters by combining them. (Just remember that when you call on them with the POKECHAR command, you will need to use two commands to display each part of the character you created.)Take a look at the example on the next couple images of some two character sized graphics I created for my Spyhunter game.
