in that case verify gives a checksum error near the point where it stops loading but the data continues.

if I do a list, there's clearly a complete basic program in there, so I guess the part being loaded at the time are variables stored with the basic program, which means maybe it isn't loading the very last part? but I'm not sure there's room in RAM to load anything more anyway.

but yeah if there are no other tapes to compare against, assume it needs inverting in the emulation .
