@PromptSlinger You will be surprised how much any single model out there can understand any Z80 code.
You can ask them to explain complex code directly or just try find old bugs, secret combos, compression techniques, whatever... Or ask them to write new code and debug it using the emulator.

AI slop has arrived on ColecoVision!

I’ve completely revamped Gearcoleco:

- MCP Server for AI-assisted debugging and hacking
- New debugging tools
- New SDL3 app
- Many new features and bug fixes

Use it to develop games or hack existing ones using AI!

@elseniorx1989a Puedes encontrarme en el server de RetroArch en Discord (https://t.co/4fOCKzQZgR).
Si es un juego nuevo posiblemente el autor no haya publicado detalles del mapper o tenga protección de copia. En esa caso no voy a emularlo por respeto al autor.

[Nacho Sánchez Ginés @drhelius]

Now it's time for a completely revamped Gearboy (Game Boy emulator), featuring:

- MCP Server for AI-assisted debugging and hacking
- New and improved debugging tools
- Improved accuracy
- Many new features and bug fixes

@HigenekoTech Have you tried using Geargrafx MCP server connected to GitHub Copilot?
You can ask it to load the game in the emulator and explain you the boot process as it is being executed

[Nacho Sánchez Ginés @drhelius]

@beta_men Fixed in latest dev build

[Nacho Sánchez Ginés @drhelius]

I've completely revamped Gearsystem (Master System / Game Gear emulator) with:
- MCP Server for AI-assisted debugging and hacking
- New and improved debugging tools
- Improved accuracy
- New mappers
- And many new features and bug fixes

@beta_men Thanks for reporting, although it is better if you use GitHub as I may miss it here

[Nacho Sánchez Ginés @drhelius]

@SynabunAI I added an embedded MCP server in 4 of my emulators, Master System / Game Gear, PC Engine / TurboGrafx, Lynx and now Game Boy.
Colecovision will follow next.

@ssh4net Depending on how you see it, there is one for the container and on for the actual window. If you have more than one window in a container it makes sense

[Nacho Sánchez Ginés @drhelius]

@ssh4net I love my close buttons

[Nacho Sánchez Ginés @drhelius]

@djmarco75_ @libretro The other emus are old and they're hard coding the refresh rate which is quite inaccurate. Lynx has variable refresh rate. I improved the way the core reports the current FPS, I hope that solves the issue. You may want to update and try again.

[Nacho Sánchez Ginés @drhelius]

Thanks again to the amazing team @libretro my new Gearlynx Atari Lynx core is now available as part of RetroArch!

[Nacho Sánchez Ginés @drhelius]

@djmarco75_ @libretro Thanks I'll check it out. I'm guessing other emus are just emulating incorrectly at 60 fps no matter what

[Nacho Sánchez Ginés @drhelius]

@djmarco75_ @libretro In this list you have the refresh rates of the different games. Can you confirm that the issue is on the 75hz games (like Klax and California games) and not on the 60hz games (like Blue Lightning)?

[Nacho Sánchez Ginés @drhelius]

@djmarco75_ @libretro Can you confirm if you have vsync enabled and disabling it works for you? Just to understand if this is the problem or there is something else

[Nacho Sánchez Ginés @drhelius]

@beta_men Got it. I was testing another prototype version

[Nacho Sánchez Ginés @drhelius]

Debugger in Gearlynx. Everything can be controlled in Claude Code or GitHub Copilot using the integrated MCP server

[Nacho Sánchez Ginés @drhelius]

@beta_men I can't reproduce it. In what situation did it crash for you?

[Nacho Sánchez Ginés @drhelius]

@djmarco75_ @libretro I can repro it setting Vsync with swap interval 1. Swap interval "auto" works on my system but I recommend disabling vsync on RA because Lynx is variable refresh rate

[Nacho Sánchez Ginés @drhelius]

@djmarco75_ @libretro California Games is 75hz, are you forcing 60 fps, using vsync or something like that?

[Nacho Sánchez Ginés @drhelius]

@beta_men Thanks, will take a look
