No.23155 cuavas Administrator 11 days ago	FWIW my cleanup of the E1 recompiler code hasn’t fixed this so far. I’m fixing issues as I find them in the code, I haven’t actually tried to work out what’s going on with this game specifically.
No.23159 cuavas Administrator 7 days ago	Also, you can get this game to misbehave when it comes to credits with the interpreter (-nodrc) as well. If you insert just one coin, play until you lose, then insert more coins at the continue screen, the game won’t recognise them, and pressing the button will just make the continue countdown tick. However, if you insert several coins before starting the game, you can continue.

The attract mode consists of several parts: * Title screen/logo * Porn montage * Stage selection demo * Gameplay demo * Picture viewer demo The point it starts failing to recognise coins is some time in the gameplay demo. Coins will be recognised any time up to the stage selection demo. The same thing happens for both -drc and -nodrc.
No.23164 cuavas Administrator 5 days ago	Just as a sanity check, I tried MAME 0.251 (yes, the sound is horrible), and this isn’t a regression in the interpreter. Even back then, inserting a coin after the gameplay demo isn’t recognised with -nodrc. I’m not sure exactly why 128c29c52f4d57789fa4ad51271ca58bfc815dfc fixes whatever made the DRC get confused earlier than the interpreter, but at least it’s consistent now.
No.23165 Haze Senior Tester 4 days ago	I think it's some kind of delayed protection
No.23166 cuavas Administrator 3 days ago	Yeah, it’s apparently protection. See over on GitHub where it’s easier to format things better: https://github.com/orgs/mamedev/discussions/190
