Arcade - Tropical Angel:
- Fixed color palette to more closely represent arcade monitor output (thanks to David Haywood for the picture).
- Added color lookup table for more accurate RGB333 to RGB888 scaling in place of the simpler concatenated scaling.
- Updated framework (pll optimizations from FPGAzumspass which saved logic and helped meet timing closure, use full output range over analog ypbpr output from wickerwaka)

New arcade core: Sega/Gremlin VIC Z80

https://github.com/MiSTer-devel/Arcade- ... Z80_MiSTer

The Sega Enterprises/Gremlin Industries Z80-based 'VIC' (video interface chip) hardware was introduced around 1977 and was for many arcade games through until 1981 when it was superseded by the G80 system.

This hardware uses dedicated analog sound boards unique to each game, which are very difficult and time-consuming to implement on an FPGA. Due to this the core only currently supports 2 out of the 20 odd titles released on this hardware:

- Carnival (1980) - notable as the first arcade game with a bonus round and the only game on the VIC hardware to have music!
- Pulsar (1981)

Many more games are playable but as they have no sound I have not included them in this release. If you want to try them out then check out the /unreleased folder in the repo.

- Simplify rgb logic (reverts my amateur LUT change from last time) to resolve a marginal timing issue observed, should see no visible differences.

Slug Cross:
- Updated framework

CoCo3 update 20240205
----------------------------------
1. For cycle accurate 6809, changed PH2 to cpu_cycle_ena. (Improve timing of control register writes)
2. Changed PIA(s) addressing to allow complete mirror through FF00-FF3F
3. Corrected usage of SG6 enable (SW5 in orig code) which allows the usage of SG6. Formerly it was used to
enable artifacts. That is no longer true. For most compatibility it has be relabeled 'CoCo3 LC',
and it default setting is Yes which is fully compatible with the CoCo3. [setting no allows SG6 mode].
For some OS9 software this must be set to 'Yes' which is the default.
4. Added 'Artifact Type' menu in 'Video Settings' menu. Settings are 'MESS', 'Simple', and 'NONE'. 'MESS'
is the default and has improved fidelity over 'Simple' which was previously implemented in connection
with SW5 [see above]. Again, the default should be used. The artifact emulation can be turned off
by setting the option to 'NONE'. The 'Artifact Color Set' choice is only valid for 'MESS' and 'Simple'
artifact settings.
