No.02099 etabeta Developer Aug 17, 2008, 20:50 edited on: Aug 17, 2008, 20:52	I can confirm the issue in chinagat and saiyugou, but it's probably due to missing background roms (the NO_DUMP roms you're warned about at start) On the other hand, the bootleg sets work perfectly here, see the snap I added. Also, notice that this kind of issues are Major, not Critical. Please read rules and instruction before posting a bug. I leave open the report for the moment, in case anyone else experience the issue also in the bootlegs (which have background roms dumped)
No.02102 Tafoid Administrator Aug 18, 2008, 01:08	That's correct. It's a graphic rom which is labeled in source as NO_DUMP: ROM_REGION(0x40000, "gfx3", ROMREGION_DISPOSE ) /* Background */ ROM_LOAD( "a-13", 0x00000, 0x10000, NO_DUMP ) ROM_LOAD( "a-12", 0x10000, 0x10000, NO_DUMP ) ROM_LOAD( "a-15", 0x20000, 0x10000, NO_DUMP ) ROM_LOAD( "a-14", 0x30000, 0x10000, NO_DUMP ) The warning you get from MAME in this case which requires you read and type "OK" One or more ROMs/CHDs for this game are incorrect. The game may not run correctly As a result, since it's not explicitly an emulation error and simply an already documented bad file, there should be no bug entered for this.
No.02105 etabeta Developer Aug 18, 2008, 06:22	Therefore, I guess you have no problems with the bootlegs either, right? Just to be sure, because I left the bug open just in case the bootlegs had a windows only bug
No.02108 Haze Senior Tester Aug 18, 2008, 09:19	the screenshots show what you get without the correct background roms. the real background roms are in custom blocks on the original PCB, they might match the bootleg roms, but this has never been confirmed (and there are a few 'bad' looking tiles on the bootlegs, which might be a result of the bootleggers dumping the custom blocks incorrectly)
No.02111 etabeta Developer Aug 18, 2008, 12:22	ok, case (and report) definitely closed
