Yes, of course emulation is less developed on Raspberry Pi. It's ok for standard emulation but you you may run into problems with  the most technical games.
If you encounter problems with a game on your Raspberry Pi, maybe you should test it on PC with one of the emulators I adviced you to verify if the problems persist  ;)
From the news on a patreon posting recently. That could be about to change. One of the more modern emulators that has previously only been X86 Mac/Windows/Linux is making a leap ahead with an Apple M1 Native release, and as an aside of this a Linux ARM64 version too. So coming to Pi4 / 400 near you soon... and I cannot wait!

Honestly, not sure that something nice can be done just by patching colours of a game which has been so cleverly thought out for mode 1 with 4 particularly well-chosen colors. But it's only my own opinion of course. But succeeding in making the floppy version requiring 128K work on the GX4000 by compensating the lack of memory by a good use of the ROM standard, it would be really interesting since this 128K version offers additional content :P .

And here is a new 'tour de force' from @Urusergi that offers us a new patched version of :

CYBERNOID from Hewson

d-pad = control Cybernoid craft
J1B1 = Fire
J1B2 = Cycle weapons (Bombs, Mines, Shield, Bounce, Seeker)
Pause button = Pause game (Fire 1 = Continue, fire 2 = abort game)

Features :
    - Two versions: Original title screen (McSpe signature removed) and new title screen from C64.
    - Wait for any key to skip title screen.
    - Original YXES cheat remapped on Left, Right, Up, Fire
    - Fire 2 on joypad 1 to cycle weapons.
    - Corrected score bug display and x10 bug (inherited from the original Spectrum version).
    - Corrected word 'RETREIVE' to 'RETRIEVE' in bad end level message.
    - Press fire to skip the highscore table (if no entry, PLAYER1 is used as default name).
    - Pause game with pause button (resume or abort game options).
    - Corrections of McSpe version > MCSPE to original SANDRA entry in high score table, original credits restored

This new version is fully playable with joypad 1 only, with a smart cycling system to choose a weapon, just like on the NES version of the game. It corrects historical bugs of the score display and a problem of the bonus score that was x10 by mistake. Pause button permits to resume game or quit as well and for GX4000 users, PLAYER1 will be used as default name in the highscore table just pressing fire 1 to skip it.

Small additional luxury, this version offers a new title screen based on that of the C64 version, therefore colourful in mode 0. For purists, a version with the original title screen is also available 8) .

The archive includes the first patched version from @Phantomz, and DSK files of the @Urusergi version for CPC users as well as CPR files.

Enjoy one of the most famous CPC games in this ultimate version, bug free, with a new title screen and 100% joypad 1 gameplay ;D .

Agree with you, iXien,  about well chosen 4 colors. For me it's one of my favorite CPC games. Now on gx4000 thanks to this amazing scene.
CPC version is same as Atari ST with better music on CPC.

But I'm great fan of Ayor61 CPC+/gx4000 works and recoloring versions. New life for CPC+ system. Thanks Cyrille !!! (Konami's Ping Pong... simple but so nice palette change, yeahhhhh)

back to Prohibition: Red blood as at arcade Empire City??

CPCEC is the emulator I launch daily, to play from the oldest CPC games to the latest homebrews and GX4000 conversions before transferring them on my real console ;)
Ah, I should have been clearer - I meant available for my Raspberry Pi.

David Skywalker is working on retroarch/libretro/retropie CPC+ core from Colin Pitrat/caprice32 research

And you would check SugarPi , a Rasp baremetal emulator... it's my GX4128 system  8) (thanks Lone)

Ok guys, as you can easily suppose, @Urusergi made the same work on Cybernoid 2, once again with some bonuses :

CYBERNOID II from HEWSON

d-pad = control Cybernoid craft
J1B1 = Fire
J1B2 = Cycle weapons (Bombs, Mines, Shield, Bounce, Seeker)
Pause button = Pause game (Fire 1 = Continue, fire 2 = abort game)

Features :
    - Wait for any key to skip title screen.
    - Original ORGY cheat remapped on Left, Right, Up, Fire
    - Fire 2 on joypad 1 to cycle weapons.
    - Center screen.
    - Colour correction on standard version (INK 1 for dominant blue, INK 2 bright blue replaces INK 15 pink).
    - Corrected word 'RETREIVE' to 'RETRIEVE' in bad end level message.
    - Press fire to skip the highscore table (if no entry, PLAYER1 is used as default name).
    - Pause game with pause button (resume or abort game options).
    - Original copyright restored on (modified in the Crackponx and Aragorn cracked versions)
    - Original highscore table entries restored (modified in the Aragorn cracked version)

Archive includes patched version from @Phantomz too. DSK files for CPC users are available as well as CPR files (Urusergi version only).

The 'Plus' version offers of course new colours choosen in the 4096 colour palette, but standard version offers its own optimization. Pink colour was originally used in the tileset, resulting in a weird effect in the details of the blue elements in the background. Using a darker blue as dominant tint in the tileset, sky blue replaces pink for a more homogeneous aspect.

The version from @Urusergi offers a real console control, making the game fully playable with joypad 1. So many thanks to him  8)

I know I'll be a little off-topic (but not completely), but I just discovered a nice remix of the Cybernoid CPC/Spectrum music on Youtube and I wanted to share it with you as it seems that not a lot of people found it. Icing on the cake, a comment from Dave Rogers himself  8)

So satisfying and above all so regressive  ;D

A very long work of master @Urusergi to overcome all the obstacles and find all the necessary space in memory 8) , thwarting excessive use of the firmware, here is a new patched version of:

SPINDIZZY from Electric Dreams

Controls on title screen:
J1B1 = Start game
J1UP = Statistics (J1B2 to leave)
J1DOWN = Help (any key to leave)
J1B2 = Credits (any key to leave)

Ingame controls:
d-pad = move GERALD
J1B1 = Extra speed
J1B1 + J1B2 = Stop GERALD on any frictional surface
J1B2 + UP = Map (J1B2 to leave)
J1B2 + DOWN = Alter GERALD shape
J1B2 + J1LEFT = Change viewpoint 90° to the left
J1B2 + J1RIGHT = Change viewpoint 90° to the right
Pause button = Statistics, pause the game (J1B2 to leave)
Pause button while displaying statistics = Colours/monochrome display

The @Phantomz version is already nice, offering a gameplay using the second joypad as a mini keyboard. But I was always puzzling if it would be possible to create a full joypad 1 gameplay, just as if it would have been an official release of the game on GX4000. So many thanks to @Urusergi for making this dream come true  :D

Changing a rule of the game was necessary to make this patch possible. Now stop GERALD doesn't drain time anymore.
Another sacrifice concerns the hidden program STIX that had to be removed to free some memory space. If you want to discover this little feature hidden in the game, please use the @Phantomz version.

In short :D :
    - STIX hidden program removed to free memory
    - Main screen keys patched
    - Ingame functions map/rotate/shape patched to d-pad pressing J1B2 simultaneously.
    - Brake patched on J1B1+J1B2
    - Statistics on Pause button, pressing again pause button while on this screen switch colours/monochrome aspect.
    - Endpart modified to no longer mention the STIX program and don't call it  (@Urusergi , thank you for your patience and tenacity).
    - Brake doesn't drain time anymore.
    - Unlimited time cheat

RAR file includes DSK and CPR files for all Amstrad players, with and without unlimited time, versions from @Urusergi and @Phantomz .

After hard work on complex patches, here is something more traditional (but not less smart) to enjoy a real classic on our beloved GX4000. Once again, many thanks to @Urusergi for his talent:

SIGMA 7 from Durell

J1 UP = Forward
J1 DOWN = Backward
J1 LEFT = Left
J1 RIGHT = Right
J1 B1 =  Fire

What have been done:
    - Wait for fire to skip title screen
    - Joypad control by default
    - Control choice menu removed
    - Highscore table: 'PLAYER 1' as default name if no input.
    - Screen one character moved to the right
    - Several texts improved ('best previous score'....., 'press any key to play', all the high scores)
    - The screen was compressed so I improved the decompressor at the same time I added the &bb18 sub-routine
    - Cheats for unlimited lives and time

Have a nice day, GX4000 lovers  ;)

And here is a new conversion from @Urusergi to feed your hungry GX4000  :P :

SHARK from Players Premier

D-pad = Control the ship
J1B1 = Fire
J1B2 = Change weapons
Pause button = Pause/unpause (J1B2 to abort current game)

J1 DOWN + J1B2 = Level up cheat.

Cycle weapons using J1B2 is a very nice improvement to the original down on d-pad that clearly made the game near to unplayable at the time.

Have a nice week-end everyone  8)

A great adventure for the most motivated among us  :P But for once a CPC game needs more than a quarter of an hour to be completed, we're not going to complain  8)
