perform a basic blit
|
|
=====================
|
|
|
|
We make some changes to [001.simple_image](../001.simple_image):
|
|
1. The bitplane pointers are now reset using the copper.
|
|
2. The palette is now installed once and removed from the copper list.
|
|
2. Interrupt processing is disabled.
|
|
3. A6 is now used as the global base register for CUSTOM.
|
|
|
|
Next we use some new features in [imagecon](../tools/imagecon) that allow us to generate a shared palette based on two PNG images.
|
|
|
|
This means a sprite and background can share the single palette.
|
|
|
|
We then blit the sprite to the background.
