TRAMPOLINE
Another sportsim in 1K hires for the ZX81.

You jump on the trampoline and do tricks.
You can perform 1 trick per bounce.
You can perform a screw left and right or a forward or backward summersault.

Controls are

Code: Select all

Z = Jump			1 point
A = Screw left turn		20 points
L = Screw right turn		20 points
Q = Forward summersault		30 points
P = Backward summersault	50 points

Newline will start a new game

When you don't press Z when landing on the trampoline you will jump less high.

While in flight you can do more moves.
In flight you must do each move the number indicated on the left of the title.
When you have done all moves the multiplier will increase.
The completed moves are indicated directly after the score.
The order is :
Forward summersault
Backward summersault
Left screw
Right screw
Your score is multiplied (except single jumps) with the number on screen.
Doing all moves will therefore give a higher score.

Landing on the trampoline must be done while facing the left. When your turn
is not finished in time you wiil not land as needed and it is gameover.
How many points can you score in 2 minutes?

I tried to run it on my Zeddy, which has a "zx81x2.rom". But the program remains in the initial screen.
Same on EO, when using also the "zx81x2.rom".
But it works on EO, when using the "zx81x2m.rom", which has the original NMI-routine (necessary to use it on ZxMore), which is slightly slower than the patched NMI-routine of "zx81x2.rom".
Is that the easter egg?

no, but by heart the program might use address #7d, the JP (HL) with a CALL to to a CALL (HL)

[dr beep]

check: no use of #7D
