Asteroids (Allan Turvey)

Post by pser1 »

Hello,
some time ago I converted for the CoCo and Dragon a game created by Allan Turvey (not an AGD game, of course)
Lately I have seen that game published in the CoCo archive, but it is not my last vesion, the last one supports the CPU HD6309 and in case it was present, the game will enter native mode to help speed up a bit..
I am uploading here that last version for CoCo/Dragon with the std BEEP commands
If you happen to have the SuperSprite-FM+ (John Whitworth), then executing the game with it will enable FX effects because detecting the chip
AY-3-891x the sounds would be produced by that chip (FX)
To play the game just do:
- on a CoCo: LOADM"AST38T9M":EXEC
- on a Tano: RUN"AST38T9M.BIN"
EDIT: I forgot to tell the accepted keys:
- 'O' moves the player (triangle) clockwise
- 'P' moves counterclockwise
- 'Q' acelerates by moving the player in the direction pointed by the triangle
- 'A' moves to another position (Hyperspace mode) or sets a protector shield (shield mode)
- 'Enter' changes palette Black/White or Black/Green
- at the game beginning, 'P' switches between Hyperspace and Shield
- 'R' allows the player to redefine the working keys
Enjoy -thumbup

Hi Pere,

Very nice work!

In which address is the AY chip mapped? Would it work with the JCB Sound Extension Module?

Cheers,
Rob
