|Assigned To||Resolution||Open||OS||Windows XP|
|Version||0.171||Fixed in Version||Build||Normal|
|Summary||06154: Games with a rotary positional joystick: Some positions are skipped|
In games with a rotary positional joystick, if you rotate continuosly in a direction, eventually a position will be skipped (in most cases - see Additional Information).
This occurs only when Positional Reverse is set to on (in many cases it is by default); when off it works perfectly.
If you use the keyboard to rotate, it happens only when rotating clockwise; if you use -mouse, however, it happens also anticlockwise if you set a very low sensitivity.
|Steps To Reproduce|
Details for single games (tested with -mouse, 0 digital speed and 1 sensitivity):
gwar, hbarrel, ikari, midres, searchar, timesold, tnk3, worldwar and their respective clones: skip one position every 12.
gondo and makyosen: go back one position every 10.
ikari3j and ikari3u: go back two positions every 12.
victroad and dogosoke: skip one position every 12 if going clockwise, and two if going anticlockwise.
downtown and clones, jackalr, topgunbl: no problems - Positional Reverse is off by default (if turned on, see gondo and makyosen).

I can confirm this issue. It's very old problem.
In similiar fashion also mouse movement is sometimes not readed correctly for example when I rapidly move mouse to left, in game move to right. This was already reported - http://forum.arcadecontrols.com/index.php/topic,148821.0.html but I thought is only certain trackballs problem.

|IIRC at least for the SNK games there's actually a protection of some kind tied to this, maybe the odd skipped position is actually required.|

|I'm going to confirm this per haynor666, but we'll have to look into the SNK games and see if the skipped positions there are a BTANB.|

I doubt a core problem like this is actually a (mis)feature to fix specific drivers. :)
The drivers listed by the tester are not just SNK games.

Tested with Ultimarc U360 rotary upgrade (serving as mouse under system) and problem is still visible. Besides this it seems that even sensivity 1 is still too big value to simulate full player 360 degree spin using full U360 full 360 degree spin.
