Summary	01412: Most sets in tnzs.c: There are a number of sets in this driver that either reset/freeze or loop under certain conditions.
Description	There are a number of sets in this driver (but note, not all of them) that either reset/freeze or loop under certain conditions. Setting throttle off and -frameskip to anything other than 0 .. some will fail even -frameskip 1 (drtoppel for instance). If you use -frameskip 6 or more, all sets will give a "coin error" or "bad hardware" if you try to credit one or two times. I was told in the past that it should not matter if frameskipping is taking place and that games should respond the same as they do at normal throttled speed. This is similar in action of another bug, hotsmash0110u4red, where an unthrottled emulation choked up when credit was inserted.
Steps To Reproduce
Additional Information	If you hold down the coin button for too long (which is what happens if you're running frameskipped / unthrottled) then the games think that there is a coin jam and will reset / give an error as appropriate. This is correct behavior, not a bug, and we don't need cheap hacks to 'fix' it, thanks. the only way in which is could be considered a bug is that MAME probably isn't processing inputs for each frame when frameskipping. (which is why I guess it happens with frameskip even with throttle, it thinks you've held it down for 10 frames) Changing the drivers is not a correct 'fix' in this case tho, so it's clearly not a driver bug, it's a MAME design issue at best. - Haze (0.117)
