Are you looking for which games are button down = hi vs = lo? Or where to switch it? Or something else?
Yes, just wanted to make them all the same, for the sake of consistency. Some of them in standard mame are gear=lo, and some are gear=lo. I have converted the toggle type, and again, it turns out there are some games lo, some hi.
I have no idea which games at hi when closed, or lo when closed.
I need to double check this as I realised I had some old cfg files, but I think the following use the gear input as hi:
grchamp
konamigt
polepos/2
stocker
If you're wondering where to switch, the easiest, but most hackish is to change the PORT type definition between IP_ACTIVE_HIGH and IP_ACTIVE_LOW. This should work for almost all games. But... that would not make it into official mame, and there is a way that probably would. Much more work: complete the POSITIONAL type code as it was designed to be, and use that type.
Changing to positional type, in all honesty is probably beyond my level of knowledge, and I do not expect my changes to get into official Mame.
Thanks for the 'easy' method

I kindof got this to work by chance another way, by adding 'value="0"' to the gear input section of cfg files for some of these games (polepos & stocker) - I guess this is doing a similar thing. I will make this change for these games, but it does not work for grchamp & konamigt unfortunately - they are already set to IP_ACTIVE_HIGH, and changing to _LOW doesn't seem to do anything. Any ideas how I might be able to alter these ones?
Thanks again!
