|

*
|

* The GR page is similar to the 40-col screen
|

*
|
||||
* There are two pixels per byte:
|
||||
* - four high bits for the first pixel
|
||||
* - four low bits for the second pixel
|
||||
* - and so on...
|
||||
* So, we have 40x48 pixels and 16 colors
|

|

* The routines are not optimized!

4play source code (c) 2016, Brutal Deluxe Software
____________________________________________________________________
Hello and Happy new year 2017!
This diskette contains some Apple IIgs source code that will help you understand how to handle the 4play joystick controller card.
This demo was made in 2016 to test and support the 4play card by Alex Lucazi. Get yours at lukazi.blogspot.fr/2016/04/apple-ii-4play-joystick-card.html
The card is supported by Ninjaforce's Kaboom. We also did a conversion of Broderbund's Lode Runner to support it.
The diskette can be cold-booted or run from GS/OS.
