One thing I noticed in boot_d64.asm is that the interrupt masks are being
set (ORCC #$50) before preserving CC on the stack (PSHS Y,DP,CC).  This
means when the code later restores CC (PULS Y,DP,CC) the interrupts will
remain masked.  I don't know if any subsequent code expects the interrupts
to be enabled, but if so that could be a problem.
