Thanks for the great game. I've already loaded it into emu42 at work and have already wasted away too much time playing with it.
Thanks - but the credits should really go to Bob Colbert, I just happened to stumble across his game and thought that the idea might work on the HP-42S... :-)

I've never done any graphical programing on the 42, so I'm looking forward to looking over your code to see how it's done.
The graphics capabilities are very rudimentary on the HP-42S. Essentially, all there is to know can be found in the Owner's Manual, chapter 9: Program Input ann Output, Graphics (in my version pages 135-140) and Programming Examples and Techniques, chapter 7: Graphics and Plotting, Plotting Data from a Complex Matrix (in my version pages 214-215).

Now to transfer it to my Dell Axim PPC and then to key it into an actual 42S - probally one that can do fast speed.
I have entered it into my real HP-42S (rev A) and it is a bit slow in normal speed mode, so running it in double speed helps to make it more playable. On my Jornada 568 (I have actually ordered a Dell X50v but I'm still waiting for it to arrive!) I modified the KEYB42S.KMI so that the navigational pad maps to the keys 4,6,8,2.
Original version:
---
Scancode 38 # Up
Map 38 41
End
Scancode 40 # Down
Map 40 51
End
Modified version:
---
Scancode 38 # Up
Map 38 43
End
Scancode 40 # Down
Map 40 63
End
Scancode 37 # Left
Map 37 52
End
Scancode 39 # Right
Map 39 54
End
Best regards,
Erik
