These GameShark-family codes had their 12-hex-digit body split into 4-char pieces (800E+3290+0003 instead of 800E3290+0003). No PlayStation core applies any of them: PCSX-ReARMed rejects the entry because a 4-hex token can never pass its address gate, Beetle PSX discards tokens that are neither 8 nor 12 chars, and SwanStation parses them into pure Nop instructions, so the cheat appears to load and does nothing. Rejoined to the canonical AAAAAAAA+VVVV form used by the other 20334 PSX codes. Digits are unchanged; every code rejoins to an exact multiple of 12, and wildcards land only in value fields.

848 codes across 95 PlayStation Game Buster files are split into four-character fragments —
8006+CE68+6400where the canonical form is8006CE68+6400.None of them apply. PCSX-ReARMed hands the string to
AddCheat, which needs an eight-digit address and a four-digit value; a four-digit fragment fails the address parse. Beetle PSX drops them on its token-length check. SwanStation loads them as no-ops.The repair is mechanical: rejoin the first two fragments into the eight-digit address. No value is altered anywhere in this branch.
Tested on hardware
TrimUI handheld, PCSX-ReARMed,
cht/Sony - PlayStation/Croc - Legend of the Gobbos (USA, Europe) (Game Buster).cht. Nothing in the file applied before the change. After it, "100 Diamonds" (80074BC0+0064), "Infinite Lives" (80075234+00FF) and "Six Gobbos Found" (80074BC8+0006) all apply.What still does not work, and why it is not this change
I also tested
Crash Bandicoot 2 - Cortex Strikes Back (USA, Europe) (Game Buster).cht. "Open all Levels" (8006CE74+43C8) works. "100 Lives", "All Crystals" and "All Gems" do not.Those three carry values that look wrong for the game — "100 Lives" is
+6400where the equivalent code elsewhere in the corpus is+0064. That is a pre-existing defect in the source entries. This branch only rejoins addresses and never touches a value, so those codes were equally broken before; the difference is that previously they could not be parsed at all, so nothing in the file could be reached. Fixing their values needs a source, not a transform, and is not part of this change.How I checked it
AddCheatand Beetle PSX's token-length check, then counted the patches that would actually apply across the changed files: PCSX 36 before / 1,273 after, Beetle 36 / 1,274, none lost.cheatN_codevalue. No files added or removed, no other keys touched.
