Good afternoon VasCrabb, good to hear from you dude. Hope you're doing well. Thanks for the swift reply. Yes, I fully understand your frustration with trying to get all these different wheels and pedals working with MAME, especially when you don't own the hardware and are basically going off information you've obtained via other methods.

I have to be honest, I was just going to brush over the links you posted and move on, but something told me to click on them and I'm glad I did. I decided to read the discussion within those links in their entirety and found one piece of information that turned out to be quite useful...

You see, someone in one of those threads suggested to the person having the pedal problem, to delete his config file and restart his game. That gave me an idea and I decided to do the same on my end.

Unfortunately, in my case, it didn't resolve the pedal issue. However, I noticed one little change in my controller mappings(I'm using Rave Racer in this case). MAME mapped my gas and brake inputs to brake- and gas- by default. At this point I proceeded into the analog settings menu and low and behold....IT FIXED THE ISSUE!!!! The pedals were reading at their proper, maximum signals, and the slider bars for both pedals reached their maximum value. Great news!

However, I the story doesn't end there....I said to myself I don't want MAME mapping my pedals to gas- and brake-, and just want it to be gas and brake. So I remapped the gas pedals to normal "Joy 1 gas", and what does it do? It breaks the input again and reverts it back to reading only half the signal at full press. That's when I knew the answer, and realized I needed to map both pedals to "Joy 1 gas-" and "Joy 1 Brake-".

Unfortunately, I had NO idea how to do this, and it took a bit of trial and error, as I simply couldn't figure out how to map my pedals in this fashion. But after simply messing about with the option, I finally realized how to accomplish the task....you have to re-map the pedal input THREE times in a row before it assigns the negative value(ie Joy 1 Gas-). Now that I know this, I can now enjoy the game with full functioning gas and brake inputs. And yes, both gas and brake both need to be set to reverse(at least in Rave Racer's case).

VasCrabbs.....can you shed some light on why this was changed in MAME, where the user is required to assign their pedal inputs to have a negative value in order for them to reach their maximum input value? In older builds it was not this way. Not complaining just curious.
