No.03698 Tafoid Administrator Jan 30, 2009, 05:03	Most sets in galdrvr.c crash with this error. Likely related to 02890.
No.03699 etabeta Developer Jan 30, 2009, 10:50	this bug (and 02890) can have two different solutions, but I don't know which one Aaron would consider best. solution 1: we would need to add a DEVCB_INPUT_PORT variant which passes both the tag and a default value in case a set doesn't use that input port (a sort of read_input_port_safe for devices) solution 2: we would need to verify how these sets were using the device (since it seems they were not using it for those inputs) if the latter is considered best, then the bugs are not related one to the other.
No.03711 Luigi30 Tester Feb 1, 2009, 16:40	Wouldn't this affect more large drivers that have games with different input schemes and input port-handling devices?
