Sgt. Frog (Cambodian Game Boy Advance Bootleg)

Sgt. Frog (Khmer: ពលបាលត្រីកង្កែប Polbalotrei kangkeb) is an unauthorized Cambodian port of Keroro Gunso: MeroMero Battle Royale Z. The developer is not credited anywhere in the game, but it's assumed it was developed by Prum Meas Interactive, the game counterpart of Prum Meas Production.

Trivia
There is a cheat code that lets you choose a level, follow these steps to do this: "1. Press C (pause). 2. Press A button 25 times. 3. Press Up button 25 times. 4. Press Down button 25 times. 5. Press Right button 25 times." (It's okay if you do mistakes, press the wrong button, or press the button more than 25 times, at least you need to pause game and press it 25 times, but the most important thing is NOT TO BREAK SEQUENCE.) After this you will see a black screen with text saying: "អេក្រង់កូដ. ប្រសិនបើអ្នកកំពុងអាននេះអ្នកនឹងក្លាយជាអ្នកលួចបន្លំឬអ្នកអភិវឌ្ឍន៍ដ៏អស្ចារ្យបំផុតនៃហ្គេមនេះ។ សូមជ្រើសរើសជុំដែលជាជីវិតរមែងស្លាប់!
