[Regression] "CD Access Time" now causes issues in some games

[bslenul]

In-game musics do not play in Keio Flying Squadron, only tested with the US version, using the Libretro core on Windows 10. I've only tested on stage 1 but disabling "CD Access Time" seems to fix the issue and the music plays, but to be clear it used to work with that option enabled.

No warnings/errors in logs or anything helpful, bisected to a6002bb, by that I mean it works with the "CD Access Time" option enabled before that commit.

On a related note regarding that access time option I noticed that Wolfchild will hang on start with it enabled, and also just before gameplay when disabled, but picodrive works fine.

Edit: Ah it is already reported: #359

And indeed reverting a6002bb will remove the start hang, but gameplay start still hangs regardless of the access time option..

2 other games with issues when "CD Access Time" is enabled:

• Batman Returns: black screen after the SEGA logo.
• AH3: Thunderstrike: beeps after the SEGA logo then reboot.
