Scramble - New game for Amstrad CPC
« on: 02:37, 06 March 19 »

Hi,
After about ten months of learning and coding it's finally here, my first game in ASM.

I would like to thank everyone who contributed here to CPCwiki source codes and tutorials.
Most of all, Thargan for his sfx, music and all the help that makes the game better than it would be otherwise!

Here are some instructions for Scramble on AMSTRAD CPC 64kb:

Menu                - ESC
Start the game  - FIRE1 for Joystick, A for Keyboard
Credits              - FIRE2 or S (They do not have any meaning except that you start a new game with one click.)

Joystick controls:

Move  - Joystick
Shoot - Joystick FIRE1
Bomb  - Joystick FIRE2 or SPACE

Keyboard controls:

Move   - Cursors keys
Shoot  - A
Bomb  - S
For redefine keys go to the Menu and also more lives can be found there.


And do not forget to show your best score to see who is the best Scramble player here. 8) 



Added CPR for GX4000!
Added CDT for CPC464!

This is absolutely fantastic.
Great job!

It's fast, responsive and very playable.
Shooting ground-based installations is as satisfying as it is in the arcade.

I'm wondering about the scroll...
It looks like a very clever technique.
Are you simply changing the top of the ground, instead of scrolling the whole screen?

WONDERFUL GAME!!! Incredible that is your first production - smooth scrolling, great gameplay, very reactive and so close to the original! Absolutely awesome. Thanks a lot!!

I didn't work on the 464 though - resets after the "grid". Tried with and without mem expansion. Works on the 6128.

Great work!!

Hey!

I have tried "left right" to pass the spec screen and to press "5" to add credits and "1" for 1P start, but that not work!  ;D
Really great port, and I'm not so bad as the game well designed, as I have reached the begin of the 4th stage at the first run.

Congratulations, I love how the display and the sound does! (really close to the arcade and Vectrex version)
You made my day. Here my game for the next 3 months!!!  :-*

300% perfect arcade emulation. A very wonderful game! Great work! But surely not your first Z80 code.  ;) :)

Thank you all!

I'm also surprised at what the CPC is capable of. :o


ervin :
About the scrolling.
Everything is fake. No scrolling at all. :D
All are sprites 8x12 px for ground and 16x20 for ground enemy.
Right side tiles draw bottom of the ground and left side tiles clear tiles with last four px.
And of course they need to be drawn from left to right every 8px. And also very fast! 8)


TotO :
For that you need a MAME emulator! ;D
The CPC can do this with one button! 8)
But, I think CPC owners do not need a MAME emulator for Scramble anymore. :laugh:


GUNHED:
Yes, it is! :P :)

A great port that is played very well, it is a pleasure to have these classics so well implemented on the CPC. And one more proof that well executed, mode 1 games are very nice to watch too.
I hope you continue making great games for CPC!
Congrats!

Just thinking that 64K (best) game should made the days of real 464 stock players.

Well today my GPU died so no plans for a longplay video.
Oh well tomorrow I will run it on my real machine.


I thought I would never see this game on my cpc.
You proved me wrong and I'm thankful for that.


Thanks again Sir.

Hi,
Okay, I'll try to do something. It will only probably take a little time.
I must first check everything about a tape loader. ;D
