Screen artifact on Legend of Hero Tonma, normal?

[505turbo]

Hi all,

I recently acquired Legend of Hero Tonma for TG16, and when I play it on my console with TurboBooster connected to a 16:9 LCD TV, it has a white line on the right as seen in this image:

I do not get the line with Tonma on the Everdrive.

Anyone seen this before? I would have assumed it means there's a problem with the HuCard, but when I play it on my TurboExpress it displays fine! I don't have a CRT to test it on at the moment.

I just tested with my Everdrive on a CRT and the line is not there.

I'm no expert, but all vintage games/consoles have some sort of overscan to deal with variable tv sizes: https://en.wikipedia.org/wiki/Overscan
what you're seeing is 95% likely to be something that is supposed to be cut off by a regular CRT border. As you can see from jperryss' photo, you're getting the same amount of active game pixels on screen, and the white line is extra data that goes beyond where the actual game display ends. this overscan stuff can vary by game depending on how they coded them.

So you're just paying the price of a white line for using an output method the console wasn't designed for!

My CRT is showing the overscan area and there is no line. There's actually about 1/4" of blank space between the right edge of the image and the bezel of my CRT in that picture.

What you said about overscan is true, but that is not the case here. He's not missing any of the image, but it kinda looks like the TurboBooster is introducing that artifact.

weird! at least it doesn't affect the game, but it'd be annoying to look at.

Thanks for the replies. I tried a different Turbobooster and different console with the same results. I will try to find my RF adapter to try that as well. Hm, might be a good excuse to try to find a nice CRT too ;-)

some of the old uk TV's did that when connecting via RGB euro SCART.  The image is slightly aligned to the left.


you probably have to get into your TV's hidden system menu and play around but you could bork your TV doing this.
