Can anybody confirm this on real hardware?

:VICGOV_400 {157639} 00DB: IF or {157643} 0018: $241 > 6 //Hot Wheels passed OR {157649} 0038: $239 == 0 //Vincenzo marker not open {157654} 004D: GOTO_IF_FALSE @VICGOV_466 {157661} 0028: $247 >= 7 //Guns of Leone passed {157667} 004D: GOTO_IF_FALSE @VICGOV_461 {157674} 0038: $254[4] == 2 //Vincenzo call to unlock Chainsaw answered {157680} 004D: GOTO_IF_FALSE @VICGOV_454 {157687} 0004: $239 = 1 //open Vincenzo marker

:VICGOV_454 {157693} 0002: GOTO @VICGOV_466

:VICGOV_461 {157700} 0004: $239 = 0 //close Vincenzo marker

There are two possible mistakes here. Either $247 >= 7 was supposed to be $247 >= 9 or GOTO_IF_FALSE @VICGOV_454 should be GOTO_IF_FALSE @VICGOV_461 (probably the first, since the second correctly assumes the marker is (should be) already closed). This code works correctly in all cases except doing Hot Wheels after Guns of Leone, as it incorrectly keeps the marker unlocked, which makes this skip possible.

Similarly, I can't tell because of the video not showing, but completing Contra-Banned and all Ma missions before Blow up Dolls doesn't lock Sindacco Sabotage despite Hot Wheels not being done because it never actually checks for it and it incorrectly checks for Contra-Banned being unlocked rather than completed to lock Sindacco Sabotage. Phonecalls are also involved in this, need to answer the unlocking phonecalls before completing the "locking" missions
