The searching..Loading stuff looks like you have the shift key held down
(Your keyboard emulation might be inverted). Modify it to hold the CTRL key
down and you don't need to get the VIA setup absolutly correct.
What does your paging register (fe30) point to when it dies ?
Your ROM select looks OK because that code gets bashed while the OS sets up
the ROM type table.
Good luck. Roger.
