|07052: macplus [bdrkcast]: Performance and sound issues with macplus
This software list title (bdrkcast) runs too slowly on the macplus driver with scratchy audio, and the game is basically too sluggish to be playable as a result. I've also observed these issues on other non-software list titles such as Dark Castle 1, leaving me to believe it is a system-wide issue rather than specific to any given title.
This is the best footage I could find to illustrate how the game should actually run, i.e. without the above issues. Note that this footage may have come from a different emulator such as vMac, though I can confirm it's more accurate to the way it should be run given that I've frequently played this game and its predecessor on an actual Mac Plus.
|Steps To Reproduce
|Launch MAME with macplus and bdrkcast from the software list, hit space at the title screen, click "Play" and wait for it to go ingame (it will take a while). Use mouse to move player's arm up and down, mouse button to click, and WASD to move. From that point the speed, sluggishness and audio issues should be apparent and distinct from those of the above video.
|While I can't confirm this has never worked properly in MAME, I've been tracking this issue since before MAME and MESS merged, and shortly after the old mac drivers themselves were added iirc.
