Gameshark Fpse Android

Using the latest version of FPse (0.10.49) and I can't get cheat codes to work.
Trying to use code from with Metal Gear Solid.

EPSXe for Android is a Playstation emulator (PSX and PSOne). It is a port of the famous ePSXe for PC. EPSXe provides very high compatibility (99%), good speed, and accurate sound. It is designed for smartphones and tablets, (for 1-4 players) including a fun 2 players option with split screen mode.

I think I'm inputting them correctly, but not 100% sure as the interface is sort of ambiguous. The cheat code list looks like this:
  1. The file format is: #description of cheat code 1 XXXXXXXX YYYY ZZZZZZZZ AAAA #descripion of cheat code 2 NNNNNNNN MMMM For example for Final Fantasy 8 US-NTSC, it could be: #Zell level 20 800778a4 4a38 Currently, only 80XXXXXX, 30XXXXXX, 50XXXXXX, 1F800XXX, D0XXXXXX, D1XXXXXX, D2XXXXXX, D3XXXXXX, E0XXXXXX, E1XXXXXX, E2XXXXXX, E3XXXXXX gameshark.
  2. Download PSX - Playstation BIOS (SCPH1001.bin) It takes a lot of work to build, maintain, and improve this site and all the wonderful content you're about to enjoy.

When you open say Cheat code 1, it has a single text input box. I'm entering the code like this:
It accepts the code just fine, but I can't get any of them to actually work in-game. Any ideas?
