extra half brite mode
|
|
=====================
|
|
|
|
[Extra half brite mode](http://amigadev.elowar.com/read/ADCD_2.1/Hardware_Manual_guide/node0098.html) allows us to use 32 colors as well as 32 "half brite" versions of those colors.
|
|
|
|
I added basic supprt to [imagecon](../tools/imagecon) to output EHB mode data. It doesn't really do a great job of taking advantage of the EHB mode.
|
|
|
|
The only changes I made to the asm code to allow EHB mode was to add the 6th bitplane and make sure the copper reset the extra bitplane pointer.
|
|
|
|
We can see from the output that it's not earth shatteringly different.
