How the game does it

Main menu frame function 0x54B460 (state 2, table 0x579050): whenever a pad bit is held (0x5FCF08 ≠ 0) it calls FUN_0041a160(0), the sequence matcher:

for i in 0..5:
    if newlyPressed(0x5FCF30) & seq[i][pos[i]]:   pos[i] at 0x58483C + 4i
        pos[i]++
        if seq[i][pos[i]] == 0:                   sequence complete
            if cheatFlags(0x584710) & (1<<i): clear bit       (toggle off, no sound)
            else: set bit, play sound (FUN_00546170(0,-127,8))
                  i == 2: next mode 0x584700 = 0x0A, 0x584638 = 4  (go to the credits)
            pos[i] = 0
    else pos[i] = 0                               any other key resets this cheat

Sequence table 0x571FBC, 6 × 9 dwords (8 steps + 0). Menu key bits (FUN_0041a220, raw DIK state array 0x58226C + 4·DIK): ↑ 0x10, ↓ 0x40, ← 0x80, → 0x20; Return 0x4000, Space 0x8000, C 0x2000, A 0x400, S 0x800, Esc 0x1000, Tab 0x08, backslash 0x01. Typing a sequence works with arrows alone; no extra key has to be held (the "hold" is just that the matcher only runs while some key is down). The flag word is never saved or reset (only bit 2 is cleared after the credits), so cheats stay on until the game quits.

Decoded cheat table

Bit	Sequence	Read at	Effect	Option
0	← → → → ↑ → → ↑	0x54F5C9, VM opcode 0xC0 "hurt player" (FUN_0054f5c0)	energy (0x584E70) is not decreased → no damage, no lost lives	`health` (default on)
1	↓ ← → ↓ ↓ ← → ↓	strat property 0xEA (0x5524F4), read by the Llama strat at chapter start	property 0xFA (0x584E60, pink idol counter, chapter collectible) = 50	`collectibles`
2	← ← ← ← → → → →	FUN_0041a160, 0x54A5F6	plays the credits (CREDITS.dat) right away, then back to the main menu, bit cleared	– (one-shot, not a setting)
3	→ → ↓ ↓ ↓ ↑ ↓ ↓	0x54D6F9 (chapter finished)	chapter flags `	= 3` (collectible + gold coin, KSV +0x08)
4	↑ ↓ → ← ← ← ← ↓	strat property 0xB2 (0x550EE1)	property 0xC0 (0x584FF4, purple fruit counter) = 500 instead of 0	`fruit`
5	↑ ← ↓ → ↓ ↓ ↑ ↑	strat property 0x97 (0x55100C)	property 0xE8 (0x6DA304, charge bar) = 165 instead of 50	`charge`

Llama strat (t1l1m001 STPC 0x429536, same in all 23 level WADs) – VM short opcodes: 0x07 p = push property p, 0x14 n = pop, skip n words if zero, 0x16 n = skip n words, 0x40 p = pop into property p, 0x44 n = push n, long opcode 0x45 = push next word:

if prop[0x97]: prop[0xE8] = 0xA5000 else prop[0xE8] = 0x32000     ; 165 / 50 (20.12)
if prop[0xB2]: prop[0xC0] = 0x1F4000 else prop[0xC0] = 0          ; 500 / 0
if prop[0xEA]: prop[0xFA] = 0x32000                                ; 50

Strat property switch: FUN_00550e60 (get, 0x10A cases, table 0x552684), FUN_005509f0 (address for store, index table 0x550D64 → 0x550C78).

Patch

call FUN_0041c050 at 0x41D3EA in WinMain (right after the command line is parsed, before DirectX init) → cave: or dword [0x584710], mask (+ mov byte [0x5834D0], 1 for diagnostics) → jmp 0x41C050. The cave writes only game globals, so it needs no data block.

Hidden debug features found

Feature	State	In the mod
`-display_diagnostics` (DAT_005834D0)	works: writes `<COMPUTER>.dispdiag` (DDraw/D3D enumeration) into the game folder; FUN_0040f4f0 opens every display mode of every DirectDraw device × D3D device (FUN_00410550/FUN_00410700 = mode switch, FUN_00411000), logs caps and texture formats, closes it again, then returns and the game starts normally. On Windows with two monitors both screens flashed black for 30+ s (tester, 2026-11); invisible under Wine	option `diagnostics`, label "Troubleshooting: write display diagnostics", off by default, warning in its description (tested: ELIASPC.dispdiag, 60 KB)
`c:\kingdom_dbg.txt`	dead: FUN_0040d2c0 (called from FUN_0043c220) only creates the file with "Logfile %s started now/today (write this code!)"; the 43 debug prints (FUN_00414600) go to OutputDebugStringA (0x6DC3E8), never to the file	no
FrameAdvanceDelay (FUN_0043cb40)	slide show `In\001.bmp…` + `In\In.wav` at start, `Out\…` at exit, delay from registry `FrameAdvanceDelay` (default 1.0 s); folders are empty	no (data, not a cheat)
F4 in game	requests state 0x0C (world map) – the normal "back to map"	no
F7 in game	toggles 0x584708 → start row of the strat debug print (0x6D9DB8 = 0x20 / 0x48); nothing visible in retail strats	no
F6	screenshot `capture%d.tga`	no
`CheatTeleport`, `CheatCharge` strats	present in most level WADs; strat-only logic, not decoded	no

Level select / unlock-all is the save editor's job (--unlock), not duplicated here.

Verified in game (Wine 6, Xvfb :8, Village 1-1)

All cheats on: chapter start shows the full charge bar, pink idol 50, purple fruit 500 (img/mods/cheats_hud.jpg, original on the left).
Infinite health: running off the cliff into the sea three times – original loses an energy segment per fall (HUD shows the red segment), with the cheat the energy HUD never appears, no loss (img/mods/cheats_fall.jpg).
rewards (bit 3) decoded only, not played through to a chapter end.
Diagnostics: file written, game runs normally.
