Alex Builds His Farm & Laura's Happy Adventures Widescreen

Post by AlphaYellow »

So, both of these games also use the OpenSpace engine, Laura's Happy Adventures came out in early 1998 and Alex Builds His Farm in 1999. I have no idea what addresses to change in the game's .exe or the SNA files to get the right resolution values, aspect ratio and FOVs. I'd be glad to have some feedback, thanks.

I have no idea, but would love to know how as well. I grew up with Alex and Laura too :D . Maybe someone on this forums can help.

Making some progress, seems like the ScreenSize variable set in ubi.ini works for Alex, and adjusting the FOV like in Hype's fix really works. But sadly, this solution is glitchy in the sides beyond the 4:3 safe area, objects disappear in the sides. And this fix doesn't work for Laura. Still work in progress!

Another update, I managed to bring widescreen to Laura's Happy Adventures as well, by altering the 00 00 80 3F (4:3) to 00 00 10 3F (16:9), it's glitchy in the sides just like Alex's fix above, but it is what I got so far.

Good job! I'm very bad at hex editing so this is very impressive! I'm very curious how you found these values? It may help me in the future lol.

Well, I mostly based on the same hex values of the widescreen fix for Hype: The Time Quest (viewtopic.php?t=31049), since they use the same engine (OpenSpace), but still getting objects appearing and disappearing outside the 4:3 area whenever moving the camera around. Wondering if anyone here knows the original FOV values that the games use, they're stored in Fix.sna inside GameData/World/Levels (and probably other .sna files too). That way a non-glitchy FOV would be possible, because it really breaks immersion this way. I released a widescreen fix on PCGamingwiki for Laura and a FOV fix for Alex, but they are NOT ideal. Here are the links:

- Alex: https://community.pcgamingwiki.com/file ... m-fov-fix/

Sorry but I have no clue. I tried to also fix the FOV for Tonic Trouble but I never could find anything. But I'm not very experienced with a hex editor so someone with the right skills might be able to achieve this.

The most reliable FOV fix without the objects disappearing on the sides would be through editing a decoded Fix.sna file, I've done for both files of Alex and Laura, but I have no idea what's the default FOV value they use (tried searching for 1.2, 1.3 and 1.4 and changed to 1.786, but nothing worked), so will be waiting for someone here that has more knowledge about this :D And also changing the 00 00 80 3F part changes both the aspect ratio and FOV at the same time, which makes the sides glitchy, hence why I wanted to do through Fix.sna.
