Disable Taskswitching in WinUAE-Debugger
Hi,
I am following a prgram in the debugger and after some time it seems a task switch happens. Is there a way to do manually Disable() and re-Enable(), maybe by writing to Custom registers? regards |

Debugger is too low level feature to understand exec task switching but if you only need to temporarily switch off interrupts without using exec: clear bit 14 of INTENA (move.w #$4000,$dff09a or something similar) to disable it and set bit 14 to enable interrupts (move.w #$c000,$dff09a)
btw, don't use this in production code, always check first if interrupts were originally enabled before re-enabling them. |

Thanks Toni. You suggestion solves the issue.
W $dff09a $4000.w # disable W $dff09a $C000.w # enable |
