Are you using GB Studio v3 alpha?
AFAIK, with v3 the menu items character limit was lifted because you can't easily compute the width of a string of characters with variable-width fonts.
Let me know if that helps.
Oh yes, it's a bug in GBS that I noticed but forgot to report. It seems that variable-width fonts expect a white background. Something must be hardcoded somewhere in GBS code.
The best way forward is to open a new issue in https://github.com/chrismaltby/gb-studio/issues.
That's the reason why I didn't create black background fonts as part of this font pack. I changed the palette to recreate this effect, which won't work in your case (as I assume your game is for DMG only).
Hello,
Thank you very much for your answer. Yes, the game is for DMG only (no color).
I changed the frame (just for test), but I'm still having the same issue. Now I'm using the 'white' standard GBstudio frame and the condensed-mini font, but I can't add more than 6 characters. Text: Display Menu --> 8 options --> Layout: Dialogue
