| Summary | 06446: kothello: Display cut off at right | ||||
| Description |
In Kyuukyoku no Othello, the credits display and part of the Japanese writing on the title screen's chalkboard seem to get cut off by the edge of the screen. The gameplay demo also has a weird black bar towards the left edge of the screen but not flush with it, nor extending down to the bottom; the status display touching the right edge also seems suspicious. If this is indeed a bug, it's almost certainly caused by imperfect HD63484 emulation. |
||||
| Steps To Reproduce | Start the game. | ||||
| Additional Information | The small black bar in the upper left corner in the second screenshot doesn't always appear, and would definitely be BTANB if observed on its own. However, I think it may be a symptom of the general alignment problem. | ||||

An idea that occurred to me: Hitachi's HD63484 may be used with the HD63485, HD63486 and/or HD63487 peripheral chips. MAME does not emulate these as separate devices, and the current HD63484 device implementation might be assuming that they are typically used with it. However, the SSS8906 PCB has none of these, and the TTL circuitry it uses instead may make a difference regarding the video timings. |

03178a2e75dde8d9550bbb60275e116d4c0f0188 works around this at least well enough for now. |
