概 要フロッピーデバイスのサウンドエミュレーションでメモリアクセス違反。
詳 細At certain points during floppy access while emulating the Apple II, MAME crashes with a memory read access violation in a method related to floppy drive sound emulation.

I have encountered this crash several times already, in two different games. Since it affects the floppy drive sound, I assume other systems than apple2 could potentially be affected, but since the crash happens only intermittently and I've mostly been emulating the Apple II recently, this is where I encountered the bug.

I have added the post-crash console output to the end of this description.

The two games I have so far encountered this bug in were Karateka and Hi-Res Adventure #0: Mission Asteroid. I played both of these games from disk images in the .WOZ format, which have been loaded into a diskiing drive in slot 6. The command line I use for my basic Apple II emulation configuration, which so far I have encountered the crashes in, is (triple quotes because I use PowerShell):

.\mame apple2 -sl0 """""" -sl4 """""" -sl6:diskiing:1 """"""


i.e. I remove the default language card from slot 0 and Mockingboard from slot 4 (which I don't think should have any impact on the crash), and I remove the default second floppy drive from the Disk II NG controller in slot 6. So far I could not determine if the crash also happens in the default configuration, with two floppy drives.

Full device configuration is as follows:

再現手順1. Start Apple II emulation with Disk II NG Controller and a 5.25" SD drive
2. Load .WOZ image of Karateka (CRC32 579992FD) into drive
3. Play game

The crash happens at random times during floppy access. Most recently, it happened after the game tried to load more data after a cutscene in the final level (dungeons). However, it has also happened earlier in the game, and at other times I have also been able to play the game to completion without a crash.
追加情報I will continue trying to gather more information, by checking for reproducibility of the crash with the default apple2 device configuration, and other machines using floppy drives with sound emulation.
