I noticed that too with some high res games. I don’t know why, though. The only explanation I have is that maybe Tempest is a vertical game? At least I think the core is passing Rotation uniforms of vertical game.
BTW, I’ll release a new version with some bug fixes and a new base preset called vector based on glow-trails. It works well with vector games.
Is it that the auto rotation algorithm is no longer detecting the game as being vertical when hi-res mode is enabled?
It doesn’t detect. The core pass a uniform to the shader “informing” it’s running a vertical game.
And, in fact, Tempest is considered Vertical by Mame and FBneo.
New update,
Few changes to base presets (playing around with guest’s new features 
)
added few new systems for Uborder with Duimon’s potato overlays: Virtual Boy, Vertrex, some atari systems, 3do and few more…
vetrex’s presets use wildcard so if games are named correctly it should detect them.
I can’t begin to describe how much joy it brings me that people finally realized they can install my packs and use my graphics “in place” without violating my license or even asking permission.
That you all feel they are worthy also fills me with pride. 
Your graphics are simply pro level graphic design stuff!
you should be proud and we (users) should feel very lucky to have the option to use them!
hope it was “without”
LOL! Yes it was. I edited the post.

hi,
Does it fail with every presets or just a specific one? witch preset did try you load?
I know this error is related to you using an old crt-guest-advanced. Just update it to the latest in his thread and it’ll fix it.
There was a small change in the ‘intres’ pragma limit values in the latest update. So you need uborder AND crt-guest-advanced updated to latest for them to no conflict with those limits.
Most presets failed, Super Famicom for example. While some Arcade presets worked fine (I didn’t test thoroughly).
I’m on the latest Online Updater shaders, except Uborder which is one version above (0.3.4). I’ll just wait for it to catch up then.
Guest shaders may take some time to update the official libretro repo (some times it takes months). If you don’t update manually from his link, you’ll be stuck with that conflict until it’s updated.
You can get the latest from guest here:
