Converted GX4000 .cpr - The topic (repository link in first post)

This time a game I discovered completely fortuitously while it seems to be more famous on C64 and Speccy :

NODES OF YESOD from Odin Computer Graphics

Of course, many thanks to @Urusergi for patching this one, I have to tell that it's a good suprise and I begin to try to complete on GX4000 last week. I hope I'm not too rusty with this kind of game as it's really playable but a bit difficult too. Sadly, it's a sequel of "The Arc Of Yesod "that isn't available on CPC.

Controls:
J1B1 = Jump
J1B2 = Pause game (any button to unpause)
Pause button = Quit game

Modifications for the GX4000 version:
    - Wait for fire on title screen,
    - All game keys patched,
    - Poke : Unlimited lives.

Rock Star Ate My Hamster
Rock Star Ate My Hamster Bizarre Edition
Rock Star Ate My Hamster Millennium Edition

Thanks @Nich for the new disc versions on cpc-power. 

Controls:
Use Joypad 1 to navigate the in game menus.

The game can be controlled by Joypad 1 using the menu's, however, if you press to name the group or a single  by accident, or make a album then you would be stuck as you need a keyboard to type.

However I've remapped Enter to the Dpad and Button 1, and Button 2 can be used to delete, so you can press the pause button for P or use Joypad 2 for RT56GF if required.
I didn't change any keys as wanted to leave them alone so it will work properly on PLUS machines.

There are both clean versions and  new Trainer versions to make them GX4000 friendly.

A very personal one that I played a lot as a child. Many thank, as usual, to @Urusergi for that. Not the best "pre-SF2" versus fighting game, for sure, but it's always interesting to offer 2 player games on G4000

We were keeping this one for the next week, but as it seems it's beginning to make turmoil on CPC Wiki, I prefer to reveal it now in order to avoid any problem of distorted version which could be released now on GX4000. So here it is :

PROHIBITION from Infogrames

The game already benefits of a GX4000 conversion, thanks to @Phantomz , but this one is really different.

After I talked to him in PM of our desire to offer a new Prohibition patch including the 128K version, Nich hardly worked on a new crack of the game that will be fully compatible on Amstrad "Plus" systems, of course including GX4000 (technically speaking).

In addition to this already fantastic work, Nich prepared a special image destined to be patch on GX4000, automatically recognizing if you have 64K or 128K RAM. So if you play it on a standard GX4000, the 64K version will be launched, as usual (nothing new for the standard GX4000, I'm afraid). But if you are the proud holder of a modded GX4000 which benefits from 128K RAM, it's the full version that will be launched. Full screen display, hide screen, high score table and most of all the boss sections, will be yours.

Many thanks as usual to @Urusergi that permitted to this version to be fully controled on GX4000

Controls:
J1B1 = Fire
J1B2 = Hide
Pause button = Pause game

Nich's work on this version:
    - "Plus" range of systems compatibility patch,
    - 64K/128K releases merged,
    - Automatic selection of the release to launch depending on the RAM available.

Modifications for the GX4000 version:
    - Wait for fire on title screen,
    - All game keys patched,
    - Poke: Unlimited time.

It remains impossible to make the 128K version working on a 64K GX4000 without the source code. But at least, there is an opportunity to enjoy it on the few GX4000s that has been 128K modded

How about Extreme with weapon select on Fire 2?

How about Frontline?
Fire 2 to throw grenades, Fire 1 + Fire 2 to set up mines.
