Rayman Pirate-Community

Was the camera culling fixed yet? The sides have disappearing objects & geometry with the widescreen changes sadly... I've tried investigating the game myself and found the code for HFOV and VFOV, but couldn't find anything for the culling issue.

Have you tried loading either the EXE or the DLL-file you were talking about into a disassembler/decompiler (e.g. Ghidra) and looked if there exists a function "GLI_xAdjustCameraToViewport"? If so, it should be very easy to find the relevant FOV value and maybe even patch it directly in the EXE ...

Hey everyone!

Here's a new EXPERIMENTAL version of the Alex widescreen patch. Based on my work on Rayman 2, I was able to fix the following things:

Un-stretched (almost) every HUD + menu item and placed them within a centered 4:3 rectangle.
Un-stretched the loading screens and menu ...

Maybe check various wrappers for the renderer. E.g. DX6 has broken ddraw support since Windows 8.
dgVoodoo (DX, Glide), nGlide (Glide, optionally with Vulkan support), dxwrapper (DX, e.g. the specific version linked on PCGamingWiki's for Rayman 2).
E.g. for dgVoodoo, also fiddle with various ...

Also I noticed when increasing the memory limit to run either Alex or Laura at 1920x1080, the game quite often runs below 60 FPS with constant FPS drops in certain areas of the map, and that's just really odd, not sure if it's the engine's issue or my computer.

Maybe try out this Dege's patch ...

So here are new versions of the patched EXE files for Alex and Laura. They are all for the English/French/German releases of the game and I cannot guarantee that they work with other versions. If you have an incompatible version, please let me know. I also attached the Python scripts I used for ...

Great work! I was always wondering if it was just easier to patch the function in the EXE that handles the FOV calculations, and you did exactly that. Would it be possible to remove the CD check in your exe as well? For me, the noCD exes at GameCopyWorld for the English/German version don't even ...

Managed to find the instruction that accesses horizontal FOV and redirected it to another offset address using OllyDbg, HxD and Cheat Engine. However, widening it to accomodate for 16:9 introduces a little clipping issues at the sides. Will try to resolve it soon.

I found something that I don't know if it's an issue of the game, but when the FOV is high (like in 48:9), the heads of characters get squished instead of stretched as they should at the sides, it's a small thing but just wanted to point it out. Happens with both your new and old solutions, it's ...

Now I remember, why I didn't try to patch the EXE in order to change the FOV before :lol: :facepalm:

Recall that in order to scale the FOV, we use the following formula: NewFOV = 2 * atan(tan( OldFOV / 2) * (3 / 4) * AspectRatio ).

Here is a decompilation of the relevant part of the function ...

Also could something be done about the missing geometry in the main menu?

The problem is that the main menu is actually its own map ("Marelle_4"), which is simply missing these objects. So unless we have a working map editor for this game (I don't know if RayMap is capable of this) and someone ...

Although I found the inventory menu seems to have its own FOV for the 3D objects that are selectable (including the backpack, which seems to be 3D as well):


... aaand you have found out where the FOV value 1.5 is used :D I've updated the fix once more :)

I made another interesting discovery ...

Well, seems like this area of the game still has the same FOV, so the image is cut off at wider resolutions. Maybe it happens in other parts of the map too, haven't tested all yet.

Thanks for the bug report!

I took another look at the fix.sna and there are, indeed, three references to the ...

Btw: If anyone is wondering how I figured out the standard FOV values for each game, here's what I did:

We know that the game stores the horizontal FOV (let's call it H) somewhere in fix.sna. From this, it somehow has to compute the vertical FOV (let's call it V). According to Wikipedia (https ...

dgVoodoo2 does not alter the internal aspect ratio, it just keeps the current one or stretches it, hence why a dedicated hex edit for the FOV is needed.

So this game uses the CPA engine (OpenSpace), and only has 3 supported resolutions: 640x480, 800x600 and 1024x768. For the 3D rendering API, it uses Direct3D 8.

It's possible to change the resolution through the file osr_dx8_vf.dll , then searching for the following values with a hex editor ...

- You must copy the files present in "Alex Builds His Farm\Gamedata\World\Sound" and that you paste them in the folder "tonictac"
- Once you have pasted them, launch the Windows command prompt by typing "cmd" in the search bar of Windows
