I use whdload pre/post scripts to change uae settings from/to JIT+max speed <=> no JIT A500/A1200 speed. I sometimes set to "fastest possible" to check bugs seen on real fast amigas.

if it's an analogue device you'll have to wait till it's supported in whdload slave. I've bought DB9 atari paddles but I wasn't able to adapt the game to analog yet.

yeah, but it means that on another machine (A1200, A4000 ...) the bug will appear. Games usually don't need cycle exact to run, and when they do, we have to fix them for whdload.
