Hi,
I loaded a fresh copy of Black Phoenix v1.5 on my Q68 with SMSQ/E v3.41
It booted up into DISP_MODE 7 (1024x768 Mode 33), perfectly, but slowly due the slow graphics mode of the Q68.
I changed the Black Phoenix screen mode to DISP_MODE 6 (512x384 Mode 33) in Qustomiser, the Black Phoenix configuration manager and rebooted.
The system loaded as shows below:

- Q68 Black Phoenix DISP_MODE 6
Slightly faster graphic mode due to slowdown of Q68.
Here playing Qjewels:
I think adding Black Phoenix to the Q68 was a mistake, as it needs a faster processing QL like QPC2 on Quad Core PC.
I will remove Black Phoenix from the supplied Q68 software and add QDT in the Extended Environment.
And maybe a Games QLWA container since there are many new games written for the QL recently.
