I learned on my grandmothers knee that a USB device has its poll rate set in the device descriptor. Little did I know that Microsoft had decided to ignore this on low speed USB devices! --- End quote --- Microsoft didn't ignore it per se. Low Speed devices are only guaranteed speeds up to 10ms per the spec. The OS has the option to poll faster though. It was just easier for them to poll all low speed devices at 8ms? instead of having to wast resources constantly figuring out the Current Bus Bandwidth Allocation. Another positive thing about Full speed speed devices is it allows a lot more options and flexibility, like composite devices so that you don't run into the Mouse Z axis limitation in Windows, and the devices run a lot faster. |

However, seeing that the system is obviously capable of the higher speeds, it is, IMHO, a bonehead decision to not offer users the option of setting that speed to whatever they wish through a simple registry entry modification. Still no need to constantly monitor or shift gears, so if that was their primary concern, this approach would have been infinitely better. RandyT |

I've been following this thread with great interest. I just ordered a TT2 from Randy mainly for playing Tempest but also the Arkanoid games. So will Arkanoid be playable with the TT2 if I patch windows to up the poll rate? Or will it just not be accurate enough? As for Centipede, I remember playing it years ago using a desktop trackball and was not impressed. It didn't feel anything like I remembered back in the 80's, even after adjusting the settings in MAME. No matter how fast I spun the trackball, it seemed to always move at the same speed. I remember sending in a bug report way back when(must have been a good 9 years ago). Sounds like the problem may still persist. |

Absolutely will your new TurboTwist 2 spinner be as accurate as any other high resolution spinner on the market after the simple poll rate patch, if you are using an OS which even requires one. Also, we keep calling this a patch, but it appears that one of the better solutions out there now is actually a new generic driver which allows for poll rate settings. Regardless, you will be enjoying your favorites as accurately as the game will allow. --- Quote ---As for Centipede, I remember playing it years ago using a desktop trackball and was not impressed.

This behavior is probably at the top of the list for me for disappointments with MAME. I don't complain too much because someone might tell me to fix it if I don't like it :). But whenever I can get Derrick's ear, I seem to bring it up. Maybe someday it will get figured out, but at the moment, it seems to be one of those enigmas. RandyT |

Maybe Our friend Derrick can do some investigating and figure out how to improve MAME's Centipede performance. ;) |
