It will only boot if you select CDTV WD33C93 SCSI from Adv Chipset.

I can't remember having to use that before, has something changed?
Remembering something happening means nothing. Config that works with 3.2 but does not work anymore is required.

EDIT: I added HDF to CDTV config, nothing happened with previous version. CDTV CD/other external boot device priorities are strange.

As I already said, thats what you get if you want to make OCS/ECS compatible palette fix. It matches existing patches.

By the way, it looks like you do ST palette correction after gamma correction. Would it be better to do that before gamma correction?
I don't know and don't care

An equivalent (at least for ST-colours) to
vi = (vi + (vi & 7)) * 2;
is
vi = (vi + (vi >> 4)) * 2;
I don't know which would be faster or produce better code.

Another equivalent would be
vi = (vi<<1) + (vi>>3);
No one should care about speed of code that only runs once and/or when user changes brightness/etc values. Readability always wins unless it is performance critical. This is not performance critical.
