Эмуляторы для Linux

[ZXMAK]

ZXMAK, не, в Xpeccy (без S) пиксельные шейдеры в opengl режиме имеются, для имитации crt (какой-никакой). В паке с конфигами по моей ссылке. Но судя по скрину - собрана не GL версия, а с софтовым рендером и масштабированием.

Хм, ccmake не видит опции для GL:

Добавил вручную cmake -DUSEOPENGL=1, собралось но падает при запуске:

видимо какая-то ошибка с неправильным вызовом QImage::QImage или до этого где-то память повредилась

Update: вот с callstack:

Дело не в OpenGL, сам OpenGL прекрасно работает.
