I just tried to make a new JFD of Ballarena ... I get the error: "Internal error: address exception at &0386DAEC
Try the version in the OP. I suspect you're running the ROM version of WindowManager, so have probably encountered an early bug that's been fixed in later versions.

Updated build in the OP for the Pi, switching overlay changes to be within an RTSupport thread to comply with the restrictions overlays impose. This “should” make the overlay frame swaps happen at 50hz and make scrolling smoother in games like Pacmania.
This build should be used in parallel with the RISC OS 5.30 ROM, which implements various changes to overlays to prevent most of the problems I’ve reported.
Overlay’s can take a while to appear if frame swapping isn’t occurring, so dropping to F12 followed by a change to a legacy screen mode might take a few seconds before the display appears. I suspect some games might also be affected by this = I’ve not checked.
I can’t actually explain why the overlay’s flicker or just doesn’t appear sometimes, other than if BCMVideo is dropping overlay changes if the GPU can’t action them immediately. I suspect it’s timing related as the overlay does eventually appear if you wait long enough.
