| セット詳細 |
 coco3 - Color Computer 3 (NTSC) | ||||
| 概 要 | MegaBugがCoco3ドライバを使うと表示が変になる。 | ||||
| 詳 細 | William Schaub discovered a graphic corruption issue when playing MegaBug on the Coco 3. It loads as a "split screen" where the top half is the entire game with slight corruption at the very bottom. The bottom half is a duplicate copy of the top half with the exception that the bottom half screen will change back and forth from a copy of the top half to complete graphic corruption. This happens whether you are moving your player character or not. This behavior is exhibited when loading the game as a CART, DSK image or CASSETTE image. The game works correctly when using the Coco 2 drivers. | ||||
| 再現手順 | Start MAME with the following command line: mame coco3 -nomouse -window -debug Insert the Megabug rompak (CART) using MAME's built-in UI. | ||||
| 追加情報 | William was able to find a workaround (with a rather interesting palette) by entering b@ff22=CD in the debugger window. The same issue happens when trying this on the official MAME binary for Windows (William has Windows v8.1). | ||||
