This is what I do. The TAP cheat file also works in shmupmame 2.2 and higher. You need to make sure game cheats are enabled in mame.ini or default game options. Remember the batch files for inp recording I sent you a while ago? If you use those it will feel like nothing is being recorded as everything happens automatically in the background. All you need to do is to save the inp files if you have something worth showing. You can use the batch files for other games if you edit them and make some small changes. I'll send you a pm with the necessary files.
