Gods Eater Burst Cheats aren't working.

[LunaMoo]

First of all there's already a thread for this game cwcheats in here.

The general problem with cwcheats happens due to emulation imperfection and constant improvements in that matter. In some sensitive games - common cheats that patch variables stored at specific location in memory depend on emulator version since the location of those variables can change when emulator changes. Similar cheats made for psp will also not work at all until emulation becomes perfect in affected games.

Aside from the end of the original thread linked earlier which afaik does have some activity and likely get's updated cheats - you can also check my basic cheats for EU version of the game here as they should work in US version as well and actually continue to do so in the future since they are made differently and don't depend on anything which would change.

As for "?" - no idea, nothing like that ever happened to me, but I'm also not using android, maybe some formatting added by whatever text editor you're using, either way it would not matter for ppsspp cheat engine even if it would end up on the end of actual code lines, so it's irrelevant to cheats working or not.
They have to be activated in cheat menu through, right from the cheat name there's a checkbox, when it's ticked it means cheat is activated, when it's empty as on your screenshot, it means it's deactivated.
Worth mentioning some cheats which change game code have a separate [Disable] cheats which are used to restore original game code or simply contradicting name affecting same thing differently. Activating both of such cheats would equal to doing only the bottom one ~ most of the time nothing ~ which generally should be obvious, but still is a mistake some people do.

Warning through, when simple cheats made in lazy ways without any checks "not work" they actually still patch memory just in wrong places effectively breaking your game. To be safe you should disable such cheats then restart emulation and reload from normal in-game save also avoid using savestates made after you activated such cheats, otherwise bad things might happen including savedata corruption and crashes.
