ZEsarUX Emulator

[Titus]

Замечания:
1. Очень медленно запускается.
2. Звук щелкает при перетаскивании окна. Видимо, это связано с использованием упрощенного кросплатформенного движка, когда все выполняется в одном потоке.
3. Очень сложно закрывается эмулятор. Необходимо сделать много телодвижений.
4. Окно не растягивается нормально на весь экран.


Notes:
1. Very slow to start.
2. Sound clicks when dragging the window. Apparently, this is due to the use of a simplified cross-platform engine, when everything is done in one thread.
3. The emulator is very difficult to close. You need to make a lot of movements.
4. The window does not stretch normally to the entire screen.

1. +1, у меня тоже, Ubuntu 24.04
2. При перетаскивании нет, а при старте, выходе и ещё в странные моменты (внутренние «окна»?) -- таки да
3. --def-f-function F10 "ExitEmulator" (--experthelp много интересного «рассказывает»)
4. не пробовал

1. +1, the same slow start, Ubuntu 24.04
2. No unexpected sounds when moving the main window. But there are strange and loud clicks on startup, shutdown and, I guess, when internal "pop up windows" are opened/closed.
3. n/a
4. Have not tried yet

ать много телодвижений.
4. Окно не растягивается нормально на весь экран.


Notes:
1. Very slow to start.
.

All the Beta versions have a delay at the beginning (3 seconds) in order for people to read the beta warning message:

"
WARNING. This is a Snapshot version and not a stable one
Some features may not work, random crashes could happen, abnormal CPU use, or lots of debug messages on console
"

Anyway, this delay exists since 10 years ago XD

Stable versions doesn't have delays
