Summary 02082: Many sets in megaplay.c: "coin interface" from megaplay remains on-screen and credits never decrease
Description When you play Sonic 2 (MegaPlay), after inserting a coin and pressing start, the 'overlayed' messages from MegaPlay system "Press 1P start" and "1 Credit" never disappear from the screen

Also the number of credits does not decrease. (I think the two issues can be related, a sort failure in updating the system status)

[reported on behalf of LastNinja2]

Additional Information: it happens not only in Sonic 2 and Shinobi 3 but also in other games, probably in all megaplay.c sets but not as frequently as in these.
