@Phantomz your remapped controls are awesome. @40Crisis the emulator is brilliant. Having loved Space Invaders since a kid I always longed for an arcade perfect port and now in 2016 I have it.

@CraigsBar

You're welcome, glad you like them, I take it you got it to work ok then.  ;D

I've added the following to the instructions.

Change the following too if you don't want the console pause button to move right!

3A 22 55 E6 04   TO   3A 22 55 E6 80
3A 21 55 E6 08   TO   3A 21 55 E6 80
3A 26 55 E6 08   TO   3A 26 55 E6 80

This will change the following;

O = Left     TO  <
P = Right   TO  >
Q = Fire     TO  Z

If you do the above, it will free up P Console Pause Button, so you could use this to insert coins if you wish instead of joystick up or down, if so don't change the following from the above list.

3A 25 55 E6 01   TO   3A 27 55 E6 01      
3A 24 55 E6 02   TO   3A 27 55 E6 02   

Change the following instead;

3A 25 55 E6 01   TO   3A 21 55 E6 08      
3A 24 55 E6 02   TO   3A 21 55 E6 08

Thank's for the videos! The emulation seems to be really well done.  :)

I've found how to change the default dip switch options for those interested.  ;)

You could change these to a default that you like so you don't need to keep changing them.  ;D

Using the uncompressed version of the emulator.

Use a HEX Editor and change the default dip switch options from

B0 D1 E1 C1 F1 C9 00 00

To

SWITCH OPTIONS

COIN ON AND EXTRA LIFE @ 1500 + PLAYER SHIPS   
B0 D1 E1 C1 F1 C9 00 00 = 3 SHIPS      
B0 D1 E1 C1 F1 C9 01 01 = 4 SHIPS
B0 D1 E1 C1 F1 C9 02 02 = 5 SHIPS
B0 D1 E1 C1 F1 C9 03 03 = 6 SHIPS

COIN OFF AND EXTRA LIFE @ 1500 + PLAYER SHIPS
B0 D1 E1 C1 F1 C9 80 00 = 3 SHIPS
B0 D1 E1 C1 F1 C9 81 01 = 4 SHIPS
B0 D1 E1 C1 F1 C9 82 02 = 5 SHIPS
B0 D1 E1 C1 F1 C9 83 03 = 6 SHIPS

COIN ON AND EXTRA LIFE @ 1000 + PLAYER SHIPS
B0 D1 E1 C1 F1 C9 08 00 = 3 SHIPS
B0 D1 E1 C1 F1 C9 09 01 = 4 SHIPS
B0 D1 E1 C1 F1 C9 0A 02 = 5 SHIPS
B0 D1 E1 C1 F1 C9 0B 03 = 6 SHIPS

COIN OFF AND EXTRA LIFE @ 1000 + PLAYER SHIPS
B0 D1 E1 C1 F1 C9 88 00 = 3 SHIPS
B0 D1 E1 C1 F1 C9 89 01 = 4 SHIPS
B0 D1 E1 C1 F1 C9 8A 02 = 5 SHIPS
B0 D1 E1 C1 F1 C9 8B 03 = 6 SHIPS


You can also have some credits by default if you wish.  ;D

Change

3A 6D FA FA 6D 3A 19 00 00 00 00 00 00 00 00 00 00 01 00 00 01 74 1F

TO   
                                                                                     
3A 6D FA FA 6D 3A 19 00 00 00 00 00 00 00 00 00 00 01 00 99 01 74 1F

The 99 is the max amount of credits you can have, change that number to what you want.  ;)

Hope some of you find them useful.  ;D

Just test it on real CPC old; very nice and so close from the original one :)

So much geekiness it makes my heart cry with joy =)

I just read that Scramble (Konami) was based on Z80 CPU.
Would it be possible for an emulator just like the Space Invaders (just saying) ?

I can't stand watching almost every 8-bit machine has its own version and not the CPC.
I still believe that i got my myopia from the green GT-65 monitor, but i can't prove it! :)

Dual z80 CPU's and dual ay soundchips... OK we have the playcity but not sure about the 'missing' CPU

This is my holy grail!!! Wish I could play it on my favorite machine.
Yes, it has 2xZ80 but the second is clocked lower so it might be a sound controller in disguise.
I really don't care if it had no sound, vector or ASCII style , I just want to play it on my CPC  ;D

Following the release of the Space Invaders Arcade Emulator for Sinclair ZX Spectrum available here:

https://www.worldofspectrum.org/forums/discussion/54108/space-invaders-emulator-for-the-spectrum-128-2-2a-2b-3

I updated the Space Invaders Arcade Emulator for Amstrad CPC with a few fixes:

V1.02:    fixes coming from zx spectrum version (18/03/2017)
      bonus sound at 1000/1500 points now works
      reset sound when using tilt   
      updated shields display
      changes in builder
      fixed a nasty bug causing emulator to hang at startup (black screen)

I tried to run the disk creation tool and it also complains that appack.exe contains a Trojan.
Anyone know if this is true?

I will try...

I didn't get any such warnings. I believe that appack.exe is the aPLib compressor.

If you're still worried about running the creation tool, compiled disc images are available from CPC-POWER.
