Heavy metal doesnt need use DLL or show vpm checked
as the score is both in the backglass and via flexDMD
so you dont want the VPM display nor freezys DLL display
VPM will get you a score box you simply dont want
and enabling external DLL will result in freezys and flexDMD fighting over control of the same display window
which will result it it either flashing back and forth, or might possibly result in 2 windows, one of which you didnt want.
The Blastoff letters are a subsection of the B2S Backglass
Some, not all, backglasses have a floating section designated as DMD, which will display on the DMD screen
But ONLY if said DMD screen is LCD, B2S can not render to a real DMD screen, B2S doesnt do dot matrix
Some things you can try (they require table restart between changes)
Run apollo
right click backglass
change it to send form to back
it may presently be form to front or standard
change to send to back
If DMD is under the backglass, you wont see it
Save that change, then restart table
see if it appears anyplace
You can also check in those same options that B2S DMD is not set to hidden.
If you still cant find it anyplace
Backup your screenres.txt (you should only have one)
then change it to the last lines pertaining to the LCD panel are all 0
that is the last 5 lines
Then relaunch the table and see if the blastoff does not at least re-appear on the backglass itself.
