(Cheats) Action Replay codes not working (tested on NES)

Converted the Action Replay files from here: http://thealmightyguru.com/Games/Hacking/Wiki/index.php/Cheat_Archive into retroarch-format per https://retropie.org.uk/docs/Cheats/

For example, Zelda II - the Adventure of Link (USA) (Action Replay).cht:

cheats = 13

cheat0_desc = "Infinite Lives"
cheat0_code = "0700:0A"
cheat0_enable = false

cheat1_desc = "Infinite Hit Points"
cheat1_code = "0773:F8"
cheat1_enable = false

cheat2_desc = "Invulnerable"
cheat2_code = "0518:03"
cheat2_enable = false

cheat3_desc = "Infinite Magic Points"
cheat3_code = "0774:F8"
cheat3_enable = false

Full set attached for reference and for others to test with: Retroarch NES Action Replay.zip

Retroarch parses and loads these files just fine, and each cheat can be toggled using the in-game retroarch UI. However, after enabling and applying them, none of the cheats become active, unlike the GameGenie cheats, which do work.

I'm using the master branch of retroarch and lr-fceumm.

Is there something I'm missing?

Start by reproducing the attached .cht files with RetroArch and lr-fceumm, then compare their Action Replay behavior with the working GameGenie cheats. Done means identifying why the NES Action Replay codes do not activate after being enabled, and documenting or correcting the relevant cheat data if the repository is responsible.
