Hijack v505 is now released. And I'd like people to try it out soon-ish if possible, and let me know if it causes any new problems.

The one change therein, is that the I2C "start" sequence has been shortened, by removing an unneeded "clock low" at the end of the "start". This means that code which talks to the DSP chip will be slightly quicker than before, running with interrupts disabled for a shorter period of time. All nice and good .. if it works reliably.

Tested and working reliably here on a Mk2 and a Mk2a unit.

Hijack v504 was released earlier, and has a single change to increase the tolerance for disks responding slower-than-spec to a WRITE SECTOR(s) request. This appears to solve a problem with Transcend SSDs in the empeg, and is totally harmless otherwise.
