POKE 9700,8E

This alters the following line:

9700	SBC A,(HL)

To ADD (with carry) instead of subtract:

9700	ADC A,(HL)

You've 9999 pounds (the max) -use these when you've to select city- (*)

POKE 8C35,99

POKE 8C36,99

You've 9999 pounds (the max) -these pokes ONLY work while you're playing a city.

POKE EFF7,99

POKE EFF8,99

POKE 9700,1A

POKE 9701,00

This alters the following line:

9700	SUB A,(HL)
9701	DAA

9700	LD A,(DE)
9701	NOP

POKE 8896,00

POKE 8964,62

This alters the following line:

888F	LD BC,(EFF7)	Jump to 88AB if *ActivePlayerCash_01 is zero.
8893	LD A,B
8894	OR C
8895	JR Z,88AB

To:

8895

JR Z,8897

So the relative jump just moves onto the next instruction.

And also alters the following line:

8962	AND A	Subtract the cost of the destination from the active players cash balance.
8963	SBC HL,DE

To:

8963

SBC HL,HL

Which means "subtract the the active players cash balance from itself", this means the player can then always afford the flight (as it's signified using the carry flag with RET NC).

POKE B709,3A

This alters the following line:

B707	LD A,08	Write 00001000 ("Hit By The Bull") to *GameState_1.
B709	LD (EFFA),A
B70C	JP 9926	Jump to 9926.

To:

B709	LD A,(EFFA)

So the game flag for setting that the player has been struck by the bull is never set.

POKE C826,18

This alters the following line:

C824	CP 40
C826	JR NZ,C832

To jump regardless of the result of the comparison:

C824	CP 40
C826	JR C832
