Thank you so much for this - I didn't know how to detect this. Elkulator does indeed support the MRB, along with its associated speed-ups. I've managed to get the code in, with just enough room left for it to still be able to run in MODE 1 on PAGE=&1900 systems.
I've re-cut the DFS and ADFS discs and ROM images with this change. Of course, in shadow (64K) mode the splash screen doesn't work, as it's a compressed screen dump that is loaded to &3000. It works fine in Turbo mode.
(Cheat confession: The splash screen was made by taking a screenshot of the MODE 7 screen in Matrix Brandy, then using the Dreamland Fantasy BBC Micro Image Converter to make a MODE 1 image from it. The compression is a slightly-adaptive RLE, very simplistic but reasonably quick to decompress with my rather ham-fisted 6502 coding ability)
