Change PvZ Plant Names Without Modding

pvz_kobo_names.lua

-- Cheat Engine Lua script to replace plant names in PvZ to names by Kobo Kanaeru.
-- Written by Miku AuahDark.
-- This file falls under Public Domain

-- To apply the plant names:
-- 1. Start PvZ and let it load until main menu
-- 2. Load 32-bit Cheat Engine and hook to PvZ process.
-- 3. Click Table -> Show Cheat Table Lua Script or press Ctrl+Alt+L
-- 4. Copy and paste this whole script then press "Execute Script"
-- 5. Cheat Engine may hang for a while, it's normal.
-- 6. After you regain control back to CE window, the script is done.

Nice project sir

Sedikit revisi, di bagian ini:

Load 32-bit Cheat Engine and hook to PvZ process

Untuk CE 64-bit, gua dah coba dan worked, kemungkinan di lapak lain gatau tapi di guanya sendiri work kok.

Saya cocokin dengan bitness gamenya. 32-bit karena PvZ itu 32-bit.
