Rolling Stones has an exploitable saucer shot that allows skilled players to achieve unlimited bonus by repeatedly hitting the left saucer without bonus resetting.
high confidence · Dave explaining the core exploit in Rolling Stones gameplay mechanics
The Rolling Stones software mod resets bonus from 19,000 to zero after saucer hits, mirroring Gottlieb design philosophy from the era.
high confidence · Dave describing the bonus reset modification applied to customer's game
Valley Games from the 1970s-early 1980s could not separate special/extra ball awards, forcing choice between points OR free game, unlike Stern's flexibility.
high confidence · Dave explaining design constraints of Valley Games vs. Stern DMD-era machines
CPR reproduction playfields have insufficient clear coat thickness and benefit from additional clear application via roller method.
medium confidence · George reporting Dave Brennan's reasoning for roller-applied clear coat on Flight 2000
Murko playfields experience ink adhesion problems where ink lifts off the wood over time despite clear coat application.
medium confidence · Dave citing John's observation about Murko playfield ink durability issues
Flight 2000 is selling for $7,000 in the secondary market, indicating strong demand for EM/early solid-state games.
high confidence · George mentioning a Flight 2000 listing in New Jersey
“they got kind of creative and kind of, it's kind of hack-a-rama inside this game”
Dave @ early — Describes the overseas import Road Show's makeshift repairs using wrong components and improper wiring
“it's like an electric field. And you disturb it... it makes the complete circuit not with two pieces of metal on the switch, but with the actual ball.”
Dave @ ~5min — Explains eddy current sensor technology to George, clarifying a novel sensor type unfamiliar to the host
“As long as you level the play field, he had a CPR repro that he was re-clearing... as long as you put this on wet it automatically self levels.”
George (reporting Dave Brennan) @ ~60min — Describes Dave Brennan's technique for roller-applied clear coat, emphasizing self-leveling properties
“the biggest piece is the preparation... you're going to get orange peel... you will find orange peel somewhere... the big piece in order to eliminate that is to buff it out”
George (reporting Dave Brennan) @ ~65min — Details the critical importance of preparation and post-application polishing in clear coat application
“I don't like all the arduino stuff... it just makes the game not like it's supposed to be versus his way... it's just, I don't really care for it, you know.”
Dave @ ~25min — Expresses preference for tasteful code mods over Arduino retrofit boards that transform classic machines
“Inventory is king. You know what? I mean, you're lucky.”
George @ ~75min — Reflects on secondary market dynamics and availability constraints in collector pinball market
“I'd rather have a flight 2000 up than a sea witch these days”
Dave @ ~80min — Personal gameplay preference shift away from Sea Witch toward Flight 2000's depth and complexity
“I won a lot of games in that. Yeah, I did. I won a lot of games in that.”
restoration_signal: Extended 7-hour service call on Road Show required adjustment of three eddy current sensor potentiometers due to drift, highlighting reliability issues with this sensor technology in 1990s Williams games
high · Dave's detailed explanation of eddy sensor maintenance challenges and field work troubleshooting
restoration_signal: Road Show imported from overseas (post-2000s) contained makeshift modifications: tungsten switch replacement for opto flipper buttons, frayed and improperly wired GI circuits with oversized fuses, incorrect parts substitutions due to unavailability
high · Dave's detailed description of hacks found during service call and plan to 'unhack' the machine with correct parts
design_philosophy: Dave notes Rolling Stones was released with exploitable bonus mechanics that should have been caught; designer likely pressured to release rather than refine, common in 1980 Gottlieb era
medium · George's observation that early 80s manufacturers prioritized getting games out the door; Dave's software mods directly address this design oversight
code_update: Dave created tasteful code modifications to Rolling Stones: bonus reset on saucer hits (19k→0), multiplier reset ball-to-ball, separate special/extra ball awards, free play mode. Approach prioritizes designer intent over Arduino retrofit retrofits
high · Detailed explanation of four specific code modifications with reasoning; customer approval of changes
technology_signal: John created custom microprocessor replacement for Gottlieb scoring circuits, eliminating timing accuracy issues in original hardware. RGB lighting added under inserts for game state visualization. Applied to Target Alpha custom build.

Dave (answering about Rolling Stones) @ ~35min — Acknowledges personally exploiting Rolling Stones' unbalanced gameplay in arcade setting
high · Dave's description of John's electronics work replacing original Gottlieb scanning circuits with instant scoring/reset via microprocessor
restoration_signal: John performed Stars playfield swap featuring custom jeweled inserts, alien/Martian imagery center piece, modified insert locations, and new rule set enhancement maintaining original chime scoring
medium · Dave's description of Stars playfield mod as 'rule enhancement' making game 'Stars version 2' without going too far from original design
product_strategy: Dave Brennan (American Pinball service manager) demonstrated roller-applied clear coat technique for CPR playfields via YouTube, citing self-leveling product properties and emphasis on preparation/polishing rather than application method
medium · George's detailed reporting of Dave Brennan's YouTube video methodology, noting automotive background and professional service credentials
product_concern: Murko reproduction playfields experiencing ink adhesion problems; ink lifting off wood despite clear coat. CPR playfields noted as having thin factory clear coat, prompting aftermarket reinforcement.
