[Graphics] Glitched tiles in bottom left corner of title screen (FR)

[Marugi]

Hello everyone,
I keep getting these glitched tiles in my title screen. It happens every time, no matter what image I use for a background.

Here is the image I used (It is 240x160):

I think the problem is that I have repeating tiles in my image, but where would I remove them? Should I leave them out in the original image, or should I not move them from my tileset to tilemap in NTME?
Thank you.

Reduce the original image. The whole point of a tilemap is so that you can use a tileset with repeated tiles removed.

So should I replace the duplicate tiles with the transparency color?

Use a program like TMC to reduce the image
