| Summary |
 08240: apple2gs: Glitchy Joystick input via gameio |
||||
| Description |
When using joystick via -gameio joy in various games, the joystick behavior is very erratic and glitchy. Sometimes the onscreen character moves in the direction indicated, then hitches or pauses or goes a different direction than where the stick is pressed. In Joystick Calibrator V1.0 (available in https://www.whatisthe2gs.apple2.org.za/files/Sports_and_Unreleased_Games.zip) with the host joystick centered, the analog X and Y values jump around, even often giving values outside the nominal 0-255 range! Note that 10 PRINT PDL(0), PDL(1) 20 GOTO 10 in BASIC does appear to work correctly. Could be a timing bug. |
||||
| Steps To Reproduce | Launch GS/OS 6.04 from HD image, then run Joystick Calibrator 1.0 from Sports and Unreleased games from this HDV image: https://www.whatisthe2gs.apple2.org.za/files/Sports_and_Unreleased_Games.zip. Center joystick and watch the values jump. Moving joystick to corners also produces glitchy, often incorrect or impossible (for the real HW) values. | ||||
| Additional Information |
Using Logitech Cordless Rumblepad via directinput, which works great in other MAME sets/systems. Tried various analog controls options but no change in behavior.

A combination of better 1 MHz slowdowns and fixing a difference between the IIgs and earlier Apple IIs solved this. Thanks to Kelvin Sherlock and John "Rastan" Brooks for assists on this. |
