Maybe we shouldn’t pollute the thread with WIPs and failed efforts? One can always open a new thread…
I agree. Final versions with comments about the games available and GX4000 conversions in general. @dragon, don’t hesitate in creating a topic about WTSS, I’ll be the first interested

Ok, it’s tuesday evening, what we’ll add to our lovely GX4000 ? Another great work from @Urusergi that worked hard with all his skill to patch and even enhanced controls on :
RASTAN
from Ocean
Controls:
- J1UP = Normal jump
- J1UP+J1LEFT/RIGHT = Normal jump left/right
- J1B1 = Thrust sword
- J1B1+J1UP = Thrust sword up high jumping
- J1B1+J1UP (while normal jumping) = Thrust sword up
- J1B1+J1UP+J1LEFT/RIGHT = Thrust sword up normal jumping left/right
- J1B1+J1DOWN (while normal jumping) = Thrust sword down
- J1B2+J1UP = High jump
- J1B2+J1UP+J1LEFT/RIGHT = High jump left/right
- J1B2+J1DOWN = Thrust sword up without jumping
- Pause button = Pause (any button to resume)
Note that this version now permits all these movements while the original game using a standard 1-button joystick required to use keys in addition for high jumps left/right, high jump up without thrusting the sword and thrust the sword down without jumping.
Modifications for this GX4000 version:
- Alternative title screen by Musicman3512, based on the one on C64;
- All keys patched;
- Main screen text modified
- Poke : Unlimited lives and energy.
Have a nice weekend everybody

Alright, let’s dive in—I’m sharing a little project of my own, tucked between two fantastic releases from our friend @Urusergi. I’ve put together a new patch for:
PIPE MANIA
from Empire / Lucasfilm Games
- J1B1 = Action
- Pause button = Pause (J1B1 = Resume, Pause button = Quit game)
I absolutely love this American puzzle game; it’s incredibly clever and features exceptionally polished level design. However, the existing GX4000 version was frustrating because it felt incomplete, beyond the usual workaround needed to bypass the high-score table, it was impossible to enter a password without a physical keyboard. Having spent the last month training an AI which I’ve been applying to increasingly ambitious projects, I’m now ready to share the fruits of my labor. Contrary to what some might assume, given the flood of projects (of varying quality) currently saturating the retrogaming scene, it’s actually quite difficult to leverage artificial intelligence effectively, ensuring it’s used judiciously to create something truly coherent rather than just a chaotic mess.
For my part, I’m focusing exclusively on patching CPC games to ensure the most comfortable experience possible on the GX4000, which has been the core mission of this project since it began in 2015.
I hope you’ll trust in my ability not just to patch these games but to upgrade them, offering an enhanced experience whenever it’s both possible and appropriate.
We’re kicking things off with Pipe Mania, for which I’ve whipped up some delightful little additions:
- All keys patched (of course);
- No more key configuration screens at launch (at laaaast
) - I added the title theme based on the musical score for the Amiga version. It didn’t exist on AY or YM sound chip, but hey, music is my core expertise
- A joypad controlled carrousel for passwords and high-score table input, the main deal with AI to play the game on your GX4000 like on any other console system.
- Some text while game is in pause just to list the options available (continue or quit)
- Nothing else… because anything more would have been superfluous
Just remember: when it comes to AI, the question isn’t whether you can do something, but whether you should!

Hello!
I’ve noticed that the Roland Ahoy! in the mega archive has not been updated with the one where I integrated the gorgeous TITAN screen. (I know that it’s about 5 years ago, but better late than never?)
The one listed in the array is the right one though.

Ok, thank you for this report. After al these yeas, I think I’ll make a new mega archive from scratch when I’ll make the 2026 update. I noticed various differences with the list, not really surprising after more than 10 years adding new failes in the same mega archive

Well, it wasn’t at the top of my release list, but since it’s ready, I can’t resist sharing it with you . We’ve had enough fun with various attempts that, in my view, are somewhat questionable.
In my opinion (and do let me know if I’m wrong), this is the only version that players would actually want to enjoy on their GX4000 with a friend:
DOUBLE DRAGON (Richard Aplin)
from Virgin Mastertronic
Controls :
- J1B1/J2B1 = Action
- J1B2/J2B2 = Grab something on the ground
- Pause button = Pause game (twice to quit game)
Modifications for this GX4000 version :
- All controls keys patched;
- Fully functional on 64 KB;
- Automatic detection of available memory with corresponding audio system adjustments:
- 64KB: in-game sound effects only (no background music, to maintain performance);
- 128KB: in-game music and sound effects;
- Music synchronization via ASIC interrupt (no more slowdowns while playing);
- Various fixes for graphic glitches and visual corruptions occurring during screen transitions;
- Fixed unintended J1B1 button inputs;
- Fixes on level 4 for progression blockers related to scaling the wall and enemies falling;
- recolored version utilizing the extended color palette;
- Player 2 now wears a red outfit in the recolored version, more matching the arcade;
- Corrected certain character shadows and outlines;
- Modified and added on-screen informational text (PAUSE, PUSH F1, countdown);
- Ten-second continue countdown, with a speed-up feature triggered by pressing J1DOWN;
- Special version featuring a cracktro by the TB Crackers. French players will know
- Pokes: Unlimited credits and time, level selector.
For me what I wanted on my GX4000 playing again this game which was a staple of my childhood and the only one to be released as a standalone title in France, an original copy of which I now cherish as part of my personal collection. I hope you’ll enjoy my little tweaks, and that they inspire you to go out and bash some mohawked punks with a baseball bat, just like in the good old days

Well, after watching @XeNoMoRPH struggle to pick up a weapon in Double Dragon, I figured it would be a good idea to allow the use of button 2 
, in addition to the standard command (FIRE1+DOWN).
