$20 LCR ESR Transistor checker project

Hello everyone.
I am updating and modifying my GM328, with more functions and cosmetic changes.
And I would like to change the question mark in case of a failed test run to another position on the screen, for example above or below the message.
Could you tell me where I can make the change.

Regards

Hello, I have that same AY-AT and I use the font FONT_8X16ALT_WIN1251_HF which best suits this model.

I want to thank madires for their selfless contribution by reading suggestions and updating the code, and also to all those who respond, especially those who, like me, do not have programming knowledge, therefore it is very difficult for us to do anything we want to change. Thanks to all.

With some work I achieved what I had set out to do, wich was something to help me identify fake transistors based on the capacity of the base-emitter junction. I also added some lines to display.c to limit it to two digits after the decimal dot because it was off-screen. (I hope it doesn't cause conflicts in other visualizations).
In the next pictures you see comparisions between some real, and really bad 2SC5200 transistors.
