Advanced Editing Tools

These are the advanced editing tools that can be run from the SMILE tool. Each tool goes into file mode when the Y button is pressed, and closes when the X button is pressed.

PAINT (Character creation)

This tool is used for creating character data for BG images and sprites. Choose colors and select tools as you draw characters in the EDIT area. Press the Y button to go into file mode, then input L and press ENTER to load the character data. Input S and press ENTER to save the data. The saved data can be used from your programs.
(Example) LOAD"GRP5:MYBG"

MAP (BG screen creation)

This tool is used for arranging BG characters to create BG screen data, for example a cityscape. Select characters from the character chart to paste them into the EDIT area. The saved data can be used from your programs by loading it into an array.

ANIM. (Animation creation)

This tool is used for making adjustments to SPDEF definition contents and registering animation data for SPANIM. If you start an animation playback test, the program data in SLOT1 will be overwritten.

WAVE (Sampling and waveform editing)

This tool is used for sampling from the microphone and using waveforms you have created as instrument sounds. A saved file can be used as an instrument sound for BEEP or BGMPLAY in the WAVSET instruction by loading it as an array.
