 gunbird2 - ガンバード2 (set 1) | ||||
| 概 要 | Vampiroを使うと4面のボス(北極)でクラッシュする。 | ||||
| 詳 細 | gunbird2 crashes during the 4th level boss fight (North Pole) when using Vampiro. Note that this doesn't happen on all PC's, only half the testers can reproduce it, any random crashes in PsikyoSH are likely to be sound overflows.Program received signal SIGSEGV, Segmentation fault.

I think this should be useful to Mr. Belmont, because the crash is caused by ymf278b sound chip core. Also Reip said us that the program reads outside the sound region and crashes and he would like to know if what is done in the same driver for s1945ii and s1945iii could be applied to this game too. I mean the following ROM_RELOAD commented in source: ROM_REGION( 0x800000, REGION_SOUND1, 0 ) /* Samples */ ROM_LOAD( "sound.u9", 0x000000, 0x400000, CRC(f19796ab) SHA1 (b978f0550ebd675e8ce9d9edcfcc3f6214e49e8b) ) ROM_RELOAD ( 0x400000, 0x400000 ) /* 0x400000 - 0x7fffff allocated but left blank, it randomly reads from here on the Iron Casket level causing a crash otherwise, not sure why, bug in the sound emulation? */ I wonder if also s1945 sound loop bug and tengai062gre could be fixed in a similar way. | ||||
