I think that the TG-16 core may have similar issues to Genesis Plus GX. When playing games like Soldier Blade, I notice that there is “warping” on objects that scroll horizontally even though the image is supposed to be 1:1 PAR with integer mode enabled. Vertical scrolling seems to be fine.
When the output is set to 1:1 PAR, you actually have to enable “keep aspect” in the core options for it to display correctly. Normally I would expect any aspect ratio correction to be disabled for a proper 1:1 image.
Screenshots were taken at 1x scale, then resized to 200% to make things easier to see.

The emulator doesn’t seem to be switching to the high resolution display mode properly either.
High resolution “arcade” mode enabled in the game, “keep aspect” disabled:

High Res + “Keep Aspect” enabled:

It looks like the high res mode is being scaled down to fit the standard TG-16 resolution.
Even in the best mode (“keep aspect” enabled, and running in low resolution) there is still some of this warping as objects scroll horizontally, so I’m not sure that it’s a true 1:1 - it just seems to be the least bad option.
