MAMEWorld Forums - HBMAME / ARCADE64 / MESSUI - Increase credits/continues by 1 increment each time you play? (Konami style)

On Konami console ports such as Gradius 5 they used to have a rather unique continue system, where as in the first time you played the game once you died you could not continue but when you went back to the title screen a message appeared saying you had been rewarded 1 extra credit/continue, so the next time you played you could continue once and then once you had used that credit and went back to the title screen then another message appearing saying you had been rewarded another extra credit (total of 2 now) and as you can guess the 3rd play through at the end you would get 3 credits and so on up to a max of say 8 credits!

I really liked this approach as it forced you to actually get good at the game rather than just spamming credits, and each time you would progress a bit further as you had limited credits forcing you to play the early stages over and over again and you would find yourself getting a lot further on your first credit over time.

Is there anyway at all this limiting credit feature could be implemented into HBMAME?
