I got it now, a few more steps to set up however.
1: Download and extract M.A.M.E. 0153b, to it's own folder.
2: Download peset038 and pe rom(s) of your choice, and put in rom folder of mame.
3: start mame, select game, and run it. before it gets to main game, will need to hit O, K, O, L(on K may need to hold until you hear ding)
4: Hit O then K this will take you into set up. (for assigned keys you can always hit TAB key) go through entire set up close door and play a game or 2
5: Next exit out of game to main menu, and select peset038 and run it. Once it's up exit it (esc) then (Esc) again to leave mame.
6: in the mame folder there should be a folder called nvram now. Open it. You will now see a couple of more files inside. 1 for the game, and 1 for the set chip.
7: Open the game file, and copy the 2 files that are there. back out of that folder and open set chip file. Paste what you copied into the file and click replace.
8: go back to mame and run it. select peset038 and run it. Once in select your denom, and activate Bill Acceptor. Press K to save changes.
9: Exit out of mame, and go back to nvram folder. open peset038 file and copy both items.
10: Go back to game file, and paste, and replace.
11: run mame again, and select your game, and run it.
12: once in game press O to open door, the K to enter set up. when you get to bill limit, I set same as hopper 9999, set to your preference.
13. finish settings close door with O. now hit TAB key and go to game config. select your preferred size bill, and BV - ID.
press Esc to get back to game. then try adding credits through BV by pressing 6 or in some cases U. If it doesn't work, either try changing ID, or play until you have credits, and re-try.
