Hello Mustafa, Hello list, I just pulled the latest version from GIT, this finally seems to have solved my problem with it crashing everytime hard. A big step forward :) Unfortunately it still doesn't run, it just exits after these messages: [...] initializing kickstart replacement You need to have a diskfile in DF0 to use the Kickstart replacement! Unimplemented Kickstart function called * configuration check trigger PAL mode V=50Hz H=15600Hz (227x312) DMACON: 4000 INTENA: 0000 (0000) INTREQ: 0020 (0020) VPOS: 0 HPOS: 0 COP1LC: 00000000, COP2LC: 00000000 COPPTR: 00000000 DIWSTRT: 0000 DIWSTOP: 0000 DDFSTRT: 0000 DDFSTOP: 0000 BPLCON 0: 0000 1: 0000 2: 0000 3: 0c00 4: 0011 LOF=0/0 So it might be just the problem of a missing .uaerc file? On the other hand, I would have guessed that you can use the GUI to create an .uaerc configuration file? So this might be another bug. I'll create an .uaerc file later manually to test this. I used Mustafa's bronx_.sh script to create the uae binary. uname -a Linux Amiga5000 2.6.26-2-686 #1 SMP Wed May 12 21:56:10 UTC 2010 i686 GNU/Linux config.log attached. No back trace, "Program exited normally."! :) Bye, Christian
