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(video interface chip) hardware was introduced around 1977 and was for many arcade games through until 1981 when it was superseded by the G80 system.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.

Arcade: Joust 2, Inferno, Mystic Marathon, Turkey Shoot:
- Updated framework

Arcade: Tropical Angel:
- Updated jt5205 adpcm module to latest
- 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
- Fixed what appeared to be potential bugs in the slug generator and border generator, no difference in behavior observed however.

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.

New Core Release : Exidy Universal Game Board 2

https://github.com/MiSTer-devel/Arcade-Exidy2_MiSTer

Games: TARG, Venture, Spectar, Mouse Trap & Pepper II

https://twitter.com/antongale/status/17 ... 8677413971

New Core Release developed by ModalModule

GBMidi - Game Boy sound chip from the Game Boy core controllable via Midi.

New I/O Board, 24bit VGA, Audio and Video DACs.

- Official release of new I/O Board, AV Board.
- ADC-In board update.
- Framework update.

All cores have to be updated with new framework to support new boards. It will take some time.
I've updated both hardware and template repositories.

Menu:
- Updated framework.

GBMidi
- added Wave and Noise Voice Channels
- choose between different waveforms for Wave, "white" or periodic for Noise
- pitch fall for both for percussion style sounds
- cycle midi channel 1 through each voice (pulse1, pulse2, wave, noise)
- Feature Complete!

Arcade: Joust 2, Inferno, Mystic Marathon, Turkey Shoot, Tropical Angel

- Updated framework to support new IO board.

CoCo3 update 20240318:
1. Changed PIA 2 addressing to align with real CoCo3 hardware and end at FF2F.
2. Re-arranged MiSTer drive LUNs to support future auto-boot from SDC drive 0.
3. Added 'Auto Run' feature. You must use slot 2 [SDC]. Take your floppy or HD
and copy it to a file name of 'boot.vhd'. This will be auto mounted to drive 0
on the SDC. In the menu, find a new item Auto Run:. It can be set to No, DOS or
AUTO.BAS. Choosing dos causes the 'DOS' command to be executed on power up. Setting
the option to 'AUTO.BAS' will cause a 'RUN"AUTO' command to be executed upon powerup.
Save your settings to cause the changes to be remembered. The Auto Run system re-arms
upon using the 'Cold Boot' menu item.
4. Fixed MiSTer / CoCo3 interface preventing the joysticks ever reaching the
max value of 63. Specifically '>' was changed to '>=' the DTOA values.
This fixes DonPan and is verified in Diagnostics 2.0.
5. HiRES[3] is used to enable some of the higher resolution graphics modes
Gary Becker designed into CoCo3FPGA, and while these are not fully
supported, the control signals such as HiRES[3] at $FF98 bit 6 affectt
the graphics engine. For some reason Color File II manipulates this bit
and was causing it not to work. This change requires the SG6 extensions
to be enabled to set HiRES[3]. So specifically in the Video Settings
insure CoCo3 LC is set to Yes. Color File II now works properly.

To Do...
1. Add support for cassette save.
2. Add Speech / Music cart
3. Fix Castle of Tharoggod

FYI - If you plan on playing with the build process - there is a new compile time feature
in config.v called CoCo3_Select_GIMEX_RAST. It is inactive and I suggest you leave
it as its is a upcoming change which is not ready.

Menu:
- Updated framework. SW2=ON switch on DE10-nano force disables 24bit mode on legacy boards (no effect on Digital I/O and v9.x).

i'm holding off new framework propagation to cores to make sure existing boards (including compatible 3rd party boards) are fine with changes.

Menu:
- Another update in framework to allow use naked DE10-nano with dual SDRAM (when SW3=ON).

Saturn:
Lots of fixes.

Menu, NES, SNES, Megadrive, MegaCD:
- updated framework

Distribution repo:
- Filter terms "genesis-core" and "megadrive-core" to discern the old and new Sega Mega Drive cores. Usage: add !genesis-core to the downloader filters to remove the old Genesis core. [2024.04.08]
- Added N64 rom database. [2024.04.03]
- Added downloader build, used by downloader to eliminate remote code execution. [2024.03.03]
