Sure thing But this statement you've made confidently a few times in different ways:
"Just a heads up if using a patched lamp table in the rom its not likely to play correctly in a real machine"
And back in February you posted this one for instance:
"Anyway I am just passing on what has been found out in a real machine with a patched fixed 1 lamp table. It definitely makes for poor play in some machines. Maybe in some machines its perfect.....but who knows which roms were written with this wider implication in them to prevent CHR hacks!
I agree rom patching is good for MFME as your not playing with real money, its for the fun of it! but in a real machine in a real arcade it is dangerous for sure!!!"
So you have this definite info that a patched lamp table affects payout/gameplay, but no idea what machine(s)?
This could be for instance using one of my early patches, not a new stealth patch... or a patch someone else made along with other hacks causing the issue... there's just so little info to go on Just that it's definitely 100% really broken, but it's impossible to say the name of a single game it's broken on! Which does kind get us stuck
Ah well, I don't have an MPU4 test rig like yours so I've no way to test any of this ideas about broken payout percentages on real hardware... so I'll perhaps come back to this when I've got the time and room to install a real machine/test rig...
If you ever do find any information about this poor play problem you keep posting, ie. just one game it actually happens on, please do update us, as then I can get to the bottom of it!
