Yeah - this question again. Found my old thread and looked at pins, read pinouts, etc. What
I don't get is, according to this..
http://www.coinop.org/kb_dl.aspx/KB/gametech/space invaders rom hack.html
I need only to connect pins 2, 23, and 24. Per the instructions no matter if its a 2764 or 28128 rom, it says to connect pin 24 to A14, yet the pinout shows pin 24 as A9 for all 3 (2716, 2764, and 27128). Does this mean it really should be connected to A14, or should I just leave it alone and only change pins 2, 23. (and 27/28 to +5v)
So long story short, in doing the single rom mod, does pin 24 stay connected to A9 or should it be connected to A14?
