You really want to set these to '1' or 'indirect'. Setting them to

This is why the 'comp_trust*=' options can be set to '2', meaning
'indirect
for Kickstart', or '3', meaning 'direct after Picasso'. The former
means that
accesses done by Kickstart will always be indirect; the latter
means 'memory
access will be indirect until the first Picasso screen is opened',
i.e.,
until after P96 has done it's memory probe thing.
I'm a little confused now. Exactly how many comp_trust options are
there?
I support 3 states in Hi-Toro: indirect, direct, after Picasso,
written as "direct", "indirect" and "afterPic" in the configuration
file. Firstly am I correct in writing these out as strings? I've
tested without errors from E-UAE but of course my JIT is permanently
disabled on my PowerPC Mac so I can't be sure I am doing it right.
Secondly it seems from your email that there may be a fourth
"kickstart" mode in addition to the three modes I currently support.
Is this correct, and if so how do I set comp_trust to "kickstart" mode?
