# Nichibutsu M68000 (Armed F) FPGA Implementation

FPGA compatible core of Nichibutsu M68000 (Terra Force Based) arcade hardware for [**MiSTerFPGA**](https://github.com/MiSTer-devel/Main_MiSTer/wiki) written by **Erin Olafson**. Terra Force PCB (different board revisions) donated by [**@atrac17**](https://twitter.com/_atrac17) / [**@djhardrich**](https://twitter.com/djhardrich).

The intent is for this core to be a 1:1 implementation of the Nichibutsu (Terra Force based) 68000 hardware. Currently in an beta state, this core is in active development with assistance from [**atrac17**](https://github.com/atrac17).

# PCB Check List

FPGA implementation is based on Terra Force and verified against an authentic Nichibutsu U.S.A Terra Force PCB and bootleg PCB.

Reverse engineering of an authentic Terra Force PCB will be done by **Erin Olafson** and schematics will be included in the repository.

# PCB Features

### Debugging Menu

A hidden debug menu can be accessed for all Nichibutsu 68000 (Armed F Based) titles. For more information on each debugging menu per game click [**here**](https://tcrf.net/Category:Games_developed_by_Nichibutsu). Each debug menu has different features to display Character, Object, Scoll, Foreground, Background, Stage Viewer, or Priority tests.

**Follow these steps to access the debug menu (OSD or Keyboard):**

> - Turn on **Service Menu** in the debug OSD options or press **F2**. Then turn on **Debug Menu** or press and hold **R**, **A**, **S**. For **Crazy Climber 2** press and hold **Up**, **LCtrl**, **Spacebar**. 
> - Toggle the **Service Menu** option off; then toggle **Debug Menu** off in the OSD or keep those corresponding keys held and press **F2**. **Note: Crazy Climber 2 is not accessible in the OSD**.

Bank 1, switch 8 enables these options on bank 2, switch 7 and 8. This enables P1 and P2 Invunerability and the ability to overclock the games framerate by holding the 2P Start Bttn. The dipswitch information was taken from mame, the overclocked framerate was discovered during core development. These features are enabled in the MRA's for the corresponding sets.</td><tr><th>Tatakae!

# Core Features

### Native Y/C Output

- Native Y/C ouput is possible with the [**analog I/O rev 6.1 pcb**](https://github.com/MiSTer-devel/Main_MiSTer/wiki/IO-Board). Using the following cables, [**HD-15 to BNC cable**](https://www.amazon.com/StarTech-com-Coax-RGBHV-Monitor-Cable/dp/B0033AF5Y0/) will transmit Y/C over the green and red lines. Choose an appropriate adapter to feed [**Y/C (S-Video)**](https://www.amazon.com/MEIRIYFA-Splitter-Extension-Monitors-Transmission/dp/B09N19XZJQ) to your display.

### H/V Adjustments

- There are two H/V toggles, H/V-sync positioning adjust and H/V-sync width adjust. Positioning will move the display for centering on CRT display. The sync width adjust can be used to for sync issues (rolling) without modifying the video timings.

### Scandoubler Options

- Additional toggle to enable the scandoubler without changing ini settings and new scanline option for 100% is available, this draws a black line every other frame. Below is an example.

### Note: (Only applies once screen flip is implemented)

> Upright cabinets share a **1L3B** control panel layout. Players are required to switch controller. If set the cabinet type is set to table, the screen inverts for cocktail mode per player and has multiple controls. Push button 3 may have no function in game, but corresponds to the original hardware and service menu. Crazy Climber 2 uses two 4-way joysticks and the second stick (right) corresponds to buttons 1 thru 4 for movement.

### Keyboard Handler

- Keyboard inputs mapped to mame defaults for all functions.
