Cheat Engine

Hacking memory

Cheat engine have a feature called Dissect mono that can help hacking game's memory. This video series about using cheat engine is really useful.

https://github.com/cheat-engine/cheat-engine

[Open Source] A powerful, all-in-one game hacking tool with an extensive feature set. Varying versions for Mac, Linux, and Android can be found here. CE video tutorials here.

CrySearch Memory Scanner

https://www.crysearch.nl/

[Open Source] A memory scanner akin to Cheat Engine, but with different features and a cleaner UI.

可以找到mono.dll的起始地址，size是39700

搜字符串

搜索IsValidForCurrentMode

this.externalProcessMemory_0.ReadStringA(address) "IsValidForCurrentMode" string
+ address 0x0C1CDFDB System.IntPtr    现在是0x1254E325

this.externalProcessMemory_0.ReadStringA(address) "CanClickToConvertToStandard" string
+ address 0x0C1CDFF1 System.IntPtr     现在是0x1254E33B

0x3B-0x25=0x16

0xF1-0xDB=0x16

this.externalProcessMemory_0.ReadStringA(address) "get_SCALED_UP_LOCAL_SCALE" string
+ address 0x0C1CDE38 System.IntPtr   现在是 0x1254E182   相差0x0638 034A‬

this.externalProcessMemory_0.ReadStringA(address) "set_SCALED_UP_LOCAL_SCALE" string
+ address 0x0C1CDE52 System.IntPtr    现在是0x1254E19C  也是相差638 034A‬

0x9c-0x82=0x1A
