FPGA compatible core of Toaplan Version 1 arcade hardware for MiSTerFPGA written by Darren Olafson. Based on OutZone (TP-018) schematics and verified against OutZone (TP-015 Conversion / TP-018) and Tatsujin (TP-013B).
The intent is for this core to be a 1:1 game play FPGA implementation of Toaplan V1 hardware for the supported titles. This project was developed with assistance from atrac17 and ππππππ¨πππ.
Rally Bike (TP-012), Demon's World (TP-016), Fireshark (TP-017), and Vimana (TP-019) are also Toaplan V1 titles and have separate repositories located here.

- Additional toggle that enables slow scrolling or separate debug feature in Tatsujin, Hellfire, Zero Wing, and OutZone. These features are present on hardware; for further details view the "PCB Information" section.
- Additional toggle to modify video timings; only use for sync issues with an analog display or scroll jitter on a modern display. This is due to the hardware's low refresh rate, enabling the toggle alters gameplay from it's original state.
| Refresh Rate | Timing Parameter | HTOTAL | VTOTAL |
|---|---|---|---|
| 15.56kHz / 55.2Hz | TP-018 | 450 | 282 |
| 15.56kHz / 57.6Hz | TP-013B, B90, TP-015 | 450 | 270 |
| 15.73kHz / 59.8Hz | NTSC | 445 | 264 |
- Additional toggle to swap inputs from Player 1 to Player 2. This swaps inputs for the joystick and keyboard assignments.
- Additional toggle to adjust the volume gain or disable playback of OPL2 audio.
- Additional toggle to increase the M68000 frequency from 10MHz to 17.5MHz; this will alter gameplay from it's original state and address any undesired native slow down.
- Native Y/C ouput is possible with the analog I/O rev 6.1 pcb. Using the following cables, HD-15 to BNC cable will transmit Y/C over the green and red lines. Choose an appropriate adapter to feed Y/C (S-Video) to your display.
-
Additional toggle for horizontal and vertical centering; the "H/V-Sync Pos Adj" toggles move the image to assist in screen centering if you choose not to adjust your displays settings.
-
Additional toggle for horizontal and vertical sync width adjust; the "H/V-Sync Width Adj" toggles address "rolling sync" and "flagging" on certain displays.
- Additional toggle to enable the scandoubler (31kHz) without changing ini settings and a new scanline option for 100% is available; the new scanline setting draws a black line every other frame. Scandoubler options pass over HDMI as well.

| Title | Joystick | Service Menu | Dip Switches | Shared Controls | Dip Default | PCB Information |
|---|---|---|---|---|---|---|
| Tatsujin | 8-Way | Service Menu | Dip Sheet | Yes | Upright | There are no known differences between regional the variants; toggling the "Game Title" to "Table" enables turn based two player gameplay versus co-operative gameplay. For further information visit the Tatsujin shmups wikipedia. To access the service menu, toggle the "Test Mode" dipswitch; press P1 Start when the grid is displayed. To access sound test, press P2 Start when the grid is displayed. Toggle the "Test Mode" dipswitch to on in-game for "No Death". For in-game pause, toggle the "Dip Switch Display" dipswitch on. When the "Game Title" dipswitch is set to "Upright", controls for both players are accessible. |
| Hellfire | 8-Way | Service Menu | Dip Sheet | No | Upright | There are differences between regional variants; the 1P Set features higher difficulty and turn-based two player gameplay versus co-operative gameplay. In-game, toggle the "No Hit" dipswitch for invulnerability. For in-game pause, press P2 Start, press P1 Start to resume. There is a slow motion debug setting; press P1 and P2 Start simultaneously. These are mappable inputs. For ease of use, these features are enabled when toggling "Scroll Debug" in the core settings; there is no need to toggle the dipswitch. The "Slow Scroll" button (P1/P2 Button 3) is not on hardware; P1 and P2 Start are merged to button 3. |
| Zero Wing | 8-Way | Service Menu | Dip Sheet | No | Upright | There are differences between regional variants; the 1P Set features higher difficulty and turn-based two player gameplay versus co-operative gameplay. For further information visit the Zero Wing shmups wikipedia. In-game, toggle the "No Hit" dipswitch for invulnerability. For in-game pause, press P2 Start, press P1 Start to resume. There is a slow motion debug setting; press P1 and P2 Start simultaneously. These are mappable inputs. For ease of use, these features are enabled when toggling "Scroll Debug" in the core settings; there is no need to toggle the dipswitch. The "Slow Scroll" button (P1/P2 Button 3) is not on hardware; P1 and P2 Start are merged to button 3. |
| OutZone | 8-Way | Service Menu | Dip Sheet | No | Upright | There are minimal differences between regional variants; other than difficulty, there is additional text in the Japanese variants. For further information visit the OutZone shmups wikipedia. For in-game pause, press P2 Start, press P1 Start to resume. There is a slow motion debug setting; press P1 and P2 Start simultaneously. These are mappable inputs. For ease of use, these features are enabled when toggling "Scroll Debug" in the core settings; there is no need to toggle the dipswitch. The "Slow Scroll" button (P1/P2 Button 4) is not on hardware; P1 and P2 Start are merged to button 4. The OutZone (Older Set) [outzoneb] has a unique feature; set both "Debug" dipswitches to on and reset in the OSD. Hold P2 Down during the boot sequence. Easiest to replicate with a keyboard. The CRTC registers are programmed for a smaller VTOTAL, enabling a higher framerate by reducing the edges of the screen. This changes the native refresh rate of OutZone from 55.2Hz to 58.5Hz and the resolution from 240p to 224p. Apart from the PCB, this is the only known emulation where this is possible. |
- Upright cabinets use a 2L3B control panel layout. Cocktail cabinets use a 2L3B control panel layout on opposite sides of the cabinet.
- If the cabinet type is set to table, the screen inverts for cocktail mode with turned based two player gameplay.
- Push button 3 may have no function in-game, but corresponds to the hardware service menu in OutZone. The "Scroll Debug" adds a button combination and is not tied to the keyboard handler.
- Keyboard inputs mapped to mame defaults for Player 1 / Player 2.
