These are the two errors I am getting when I start MAME...- Failed to Initialize Function Pointer for XInputGenState. Error: 1157- xinput_api_helper failed to intialize! Error:4294967295I am trying to use Mame 0.173 on a Pentium 4 running @ 3.0Ghz. The OS is Windows XP home service pack 3 that has been fully updated.
I've been running Mame .177 on XP SP3 without any issues on a 3.0 GHz P4 with 1 GB RAM. My XP build is not standard, but only because I removed some components with NLITE. I'm pretty sure I didn't install anything unusual. Before that, I was using .16x, and .15x before that on the same PC. I don't recall ever having to do anything special to get Mame working on XP.
I'm probably not being helpful here, but there is a simple fix. Install win7. XP is all kinds of dead.
