I had a chance to try this in the emulator this evening, and discovered this occurs wih ordinary MOS 3.50 as well! If you remove the View ROM, BASIC 4r32 doesn't work in the second processor. Looks like MOS 3.50 checks for the 6502 ROM relocation bitmap, but doesn't reset the ROM's base address to $8000 if it wasn't found. So you'll end up with the unrelocated ROM copied to its relocated address... crash!Just the two files MOS 350 NT and UTILS 350 NT in the #00000 and #1C000 slots
Basic4r32 into Rom 12, and adfs203/dfs245 etc in their usual places all from the old master megarom
Putting ViewB3.3 (again from the old master megarom) in Rom 14 as you suggested does work though
I'll sort out including a non-relocatable BASIC 4r32 that'll be useable with 3.50(NT). If View/ViewSheet/EDIT are relocatable too I'll fix those up as well. It's just 1 bit to clear in the header.
I'll be able to fix this bug for the refreshed versions, I think.
