SNK Ikari Warriors (beta):
- Ikari Warriors, Ikari JP, Victory Road, Dogou Souken:
added SNAC DB15 support (tested with DB15 Splitter for official MiSTer by Antonio Villena) and SNK LS-30 rotary native support using
custom adapter following DB15 pinout (button wires F, E, D and C carry the data), see Readme.md for instructions.
All SNAC stuff works using standard MiSTer binaries.

SNK Ikari Warriors (beta):
Update: fixed Ikari Warriors.mra incorrect buttons declaration.

SNK TANK/TNK III (beta):
Update: added SNK LS-30 rotary native support using
custom adapter following DB15 pinout (button wires F, E, D and C carry the data), see Readme.md for instructions.
All SNAC stuff works using standard MiSTer binaries.

SNK Ikari Warriors (beta):
Fix: fixed all .mra files. The ampersand (&) character, used in a text string, has been replaced in .mra files since, in fact, being xml files, it was causing validation errors.

SNK Ikari Warriors (beta):
Fixes:
- Removed the one pixel shift of the background layer (no more grey line on Ikari intro scene or yellow line at top of screen in Victory Road).
- Fixed all .mra files due to an error in the configuration of the buttons.
- Removed a silly error introduced by mistake that did not pause one of the CPUs when showing the OSD menu and caused errors when restarting the core.

SNK Athena/Fighting Golf (beta):
Fixes:
- Removed the one pixel shift of the background layer (no more strange lines in Fighting Golf).
- Added DB15 SNAC support.

SNK T.A.N.K. (beta):
- Fixed typo in setname in T.A.N.K_Japan.mra (thanks to Toryalai1).
