AAE has a laundry list of issues, but for me it's the instability of the application that has really bugged me. AAE crashes my dedicated AAE rig almost every time. Also, the spinner sensitivity controls will not allow things to be adjusted to an acceptable playing level for me, personally. This was an issue with AAE in general, the spinner sensitivity just would never get to the point where I felt comfortable playing Tempest or Vector Breakout.
My question/request is for the roms to be able to be played, I completely understand that any of the graphics stuff would be chucked of the window to run in mame. It's the cool graphics stuff that makes all these issues for me when I run AAE. The Tempest Multigame was a specific rom set that Tim integrated into AAE and Tempest GL and it looks very cool but has all the problems associated with AAE while running in this app.
I would love to set up a dedicated Tempest Multigame cabinet that boots directly to the Tempestm rom. It would never be as bright as AAE but I and a few others would be most appreciative to be able to run the Tempest Multigame in any capacity outside of AAE and deal with brightness and blurs as a seperate issue. I know there was an old post of someone that wanted to boot directly to the Tempest Multigame, maybe they will read this and chime in...
