I have noticed than when using my ZXUNO and loading some text adventures (core: 48k), like Adventureland, when the game has just loaded and then any key is pressed, border turns black. I think this also happens in DivMMC devices.
Here a pic of the TAP file and a Z80 I made from the TZX:
Not a problem as you can keep playing with no problems. Same issue in other similar adventures like Gremlins (spanish) or Ashkeron.
Anyone knows the reason?

Re: Mild issue in ZXUNO
I wonder if a multiface would suffer the same problem.
As far as I know there's no way to know the state of the border, other than by the basic system variable, which won't necessarily be the right value in a machine code program.
Ordinarily it wouldn't matter as the game would reset it as soon as it played any speaker sound, so I presume in those adventures there isn't a keyboard click.
If there's a game tape save or load option that might set it back correctly

Re: Mild issue in ZXUNO
I just looked at Adventureland and it makes sound, so it should set the border correctly, even if the DivMMC set it incorrectly
