All these codes are from me, please give credits.
As the game is hard and is only in chinese, here's few codes to help you during the playtrhough:
Infinite life:
0477; FF
Infinite cash:
0470; FF
Stat under the health (?):
047B; FF
Stat on top of your health (?):
0473; 37 (cannot go higher than 55)
Kill the enemies in one hit each:
0565; 00 (first)
0567; 00 (second)
0669; 00 (third)
Free movement on X axis:
0049; XX
01 for right, 02 for left. The enemies when you are out of bounds can remove up to 214hp, I suggest using the Infinite health code and the kill enemies with one hit. To controll yourself again, deactivate the code.
Random codes where you can mess up with Jing Ke. These codes are fail, I tryed to make them but they don't work well...
Spoiler: click to toggle
Y axis
0009; X0
0214; XF
0218; XF
It seems these are used for the Y axe. 214 and 218 must have the same value. The lowest value for 214 and 218 is 0F. If you want to go one block higher, add 16 (decimal) to the 0F.
The lowest value for 0009 is 10. Next good value are 20, 30, 40, etc.
With this code you may end up outofbounds.
FREE MOVEMENT !
005A; FF
Now you can go EVERYWHERE and walk on EVERYTHING !
It seems the first town doesn't like free movement, add 0051 01 to the free movement when you walk in that town. Deactivate it when you leave it.
Remove triangle:
0719; FF
