I just updated my Funhouse from ROM rev L-5 to L-9. I also patched the L-9 rom to eliminate LED ghosting and that works great... I'm so pleased!!!
The only problem I'm noticing is that the kicker that puts the ball in play (so you can shoot the ball) is weak now. If I run the test mode on it, it is strong and works perfectly every time. Now, it barely kicks hard enough to push the ball into the shooting lane. Half the time, the ball falls back in and the kicker has to fire again to get the ball out. While the game still works fine, it seems like there is a problem somewhere. I lubed up the kicker shaft a bit, but it didn't make any difference. it seems like something in the code fires the solenoid at half power... then if that doesn't work, it fires at full power, because if the ball doesn't make it and it kicks again, it seems to kick harder.
Is there any way to disable this? Has anyone else experienced it with the L-9 ROM? Suggestions?
