| Summary | 04475: quizmeku: Missing gfx | ||||
| Description |
Quiz Mekurumeku Story is missing gfx, question and CREDIT text since MAME 0.129u6 (see snapshot quizmeku-143u4-129u5.png). In 0.129u6 Olivier Galibert added support for System 24 tilemap linescroll modes. So i checked the new changes in video\segaic24.c (see Compare_video-segaic24_source.png). Line 706 changed to " curspr &= 0x03ff; ". I changed it back to "0x1fff;" and the gfx/text come back again. After it i checked the other Sega System 24 games. Bug #3195 (crkdown: graphic artifacts and speed drop during gameplay) and Bug #03641 (sspirits, gground: Only half of the game's frames are rendered) disappeared and the fixed Bug #2526 (mahmajn2: Missing 'special' linescroll mode) works. |

this looks like a legitimate fix to me I suspect OG wanted to change it to 3fff not 03ff. (3fff wouldn't be correct either tho, it breaks Gain Ground, the original value of 1fff is correct) I was looking in the wrong place thinking this was entirely an interrupt / timing issue then. |
