I used to find the codes from codejunkies website to find the GTA Chinatown Wars cheat codes to input and I want to find more so I used the other website: gbatemp.net and there wasn't many codes to input for Chinatown Wars.
The codes I would like to get for Europe version:
Freeze time in gang-killing missions
Heavy Cars and other vehicles (like the one in San Andreas)
Infinite Health for allies in mission like Heston or Chan (That an example people to encounter in mission)
Completed miscellaneous mission like encountering people, taxi jobs, etc.
Have all trophies in safehouse
That much of the codes that I like to get but I'm really rubbish at making a new codes at hexadecimal binary codes.
Also I found the video on youtube about the BEST Action Replay codes part 1 and unfortunately it's in US Version, NOT Europe version.
