My "victory" would be being able to code MAME myself without any help, but i need much more examples and case study so, how could i settle at this point? :P
Joking aside, i thought the function "port1_r" was the one controlling that input/memory region so what are the two conflicting things i am trying to make the code?
[OT] Are there code studies/resources that could help better understanding how to deal with MAME drivers?[/OT]
