I was talking to James Goddard, Weaponlord's designer (and several other games) and he stated that there are still things that people haven't found about the game, and I quote:

"there are also other secret things never revealed, like alternate end round taunt sets, a code for the developer special thanks on SNES (saw the genesis finally was found). It would be awesome to get stuff like that on TCRF."

Also, there was another ending planned for the character Bane, which he thought made it into the final game. It is unknown if the text and graphics for that ending where inserted in the final game though. Everything is compressed, so I can't find it with my limited skills.

Does anyone here mind taking a look and see what they can find?

I was not able to find anything new with my limited skills, but will post a little more info.

The password is stored in RAM at 7E5CF7 (+17 bytes).
Seems like only A, B, and Y are accepted.
A=33 (0X21)
B=34 (0X22)
Y=57 (0X39)
Nothing entered=13 (0x0D)

One cheat password is easily visible with a hex editor at offset 2ae6d8 (213921392222223921212139392239212121)

Zarak available on the Story mode select screen
AYAYBBBYAAAYYBYAAA

The ROM used was 'Weapon Lord (U) [!]'

Thanks, hopefully someone here can find that other hidden button code.

Assuming we're talking about the SNES version...

Well, I can tell you that there are four on GameFAQs listed as cheats. Well, there are more than four of them based off of what I have looked up in the codes... I have determined there are ten that either activate some cheat variable or does something else. However, the button codes are not in plain sight to my eyes, meaning there's an algorithm to crack open... the cheat variables are 7E204C through 7E205A. Setting them to FF FF (that's two bytes of FFs) activates a cheat. I have not determined what each one does yet...

The reason why that one cheat is visible in plain sight in hex code is because it is most likely practically given to the player as he completes the game with each character.

And I think I just made a discovery. All but one of the codes from the Genesis version work on the SNES version. Just replace C with Y. Here's the variable affected (if applicable) with each code:
YBB YYB YAB AAA BBY BAB (7E204E)
YBA AYB YYB AYA BAA YAA (7E2054)
BBB AAY ABY AYB YYY YAB (7E2056)
AYA YBB BYA AAY YBY AAA (7E204C)
BAA YYB AYA AYA AYA BAB (plays no SFX, but my guess is that it's valid)
YAY BBB YAA AYY BYA AAA (plays no SFX, but my guess is that it's valid)
BAY YBB ABB ABB ABB BAA (7E2050)
AAA AAY BYB ABY BAB YAB (7E2052)
AAY AYB BBY AAA YYB YAA (7E205A)
YYY AAY YYY AAB AYB ABB (not valid in SNES version)

So that's all but one of them. The missing code modifies 7E2058 and will give a result of zero for a cheat ID.

Damn, so the dev credit code doesn't work on the SNES version. That's too bad. I don't even feel like adding any of the other codes to gamefaqs now.

Thanks for the help KFF!

Actually, I haven't tested the codes yet to see what exactly they do in the SNES version...

To organize this a little smoother and going with that list, the following are listed on gamefaqs:
YBB YYB YAB AAA BBY BAB -Password every level
AYA YBB BYA AAY YBY AAA -Zarak available on the Story mode select screen
AAY AYB BBY AAA YYB YAA -Lit pause and slow-motion

The following are unknown:
YBA AYB YYB AYA BAA YAA
BBB AAY ABY AYB YYY YAB
BAA YYB AYA AYA AYA BAB
YAY BBB YAA AYY BYA AAA
BAY YBB ABB ABB ABB BAA
AAA AAY BYB ABY BAB YAB
YYY AAY YYY AAB AYB ABB

And these two from gamefaqs aren't mentioned above:
AYB BYB BAA ABB YYB AAB -Low player two health
BBB AAY ABY AYB YYY YAB -Death Strike always active

Now using the Genesis list and doing a little conversion, the following are possible matches:
YBA AYB YYB AYA BAA YAA -Demo Mode v.1 (?)
BBB AAY ABY AYB YYY YAB -Demo Mode v.2 (?)
BAA YYB AYA AYA AYA BAB -Knockdown Mode
YAY BBB YAA AYY BYA AAA -More health
BAY YBB ABB ABB ABB BAA -P1 different color
AAA AAY BYB ABY BAB YAB -P2 different color
YYY AAY YYY AAB AYB ABB -Developer special thanks, according to list doesn't work?

This should give something more concrete to look for.

I've been picking at the code for the game using a basic disassembler I am writing (should I talk about it elsewhere on Jul?). Here's what I determined so far (reformatted for evenness):

  ldy     $5D45                   ; $2A300E | $5D45 -> $005D45

        ldx     #$0000                  ; $2A3011

loc_2A3014:

    jsr     sub_2A3043              ; $2A3014

   iny                             ; $2A3017

   iny                             ; $2A3018

   cpx     #$0012                  ; $2A3019

   bne     loc_2A3014              ; $2A301C

   lda     #$366F                  ; $2A301E

   ldy     #$0001                  ; $2A3021

   jsr     sub_290D39              ; $2A3024

   lda     #$B8F8                  ; $2A3028

   ldy     #$0001                  ; $2A302B

   jsr     sub_290D39              ; $2A302E

   lda     #$B912                  ; $2A3032

   ldy     #$0001                  ; $2A3035

   jsr     sub_290D39              ; $2A3038

   jsr     sub_2A1041              ; $2A303C

   jsr     sub_2A1963              ; $2A303F

   rts                             ; $2A3042

sub_2A3043:

    lda     #$0003                  ; $2A3043

   sta     $0C                     ; $2A3046 | $0C + d=$0000 + dbr=$00 -> $00000C

loc_2A3048:

       lda     $5CF7,x                 ; $2A3048 | $5CF7 -> $005CF7

        and     #$00FF                  ; $2A304B

   ora     #$2000                  ; $2A304E

   sta     $0688,y                 ; $2A3051 | $0688 -> $000688

        iny                             ; $2A3054

   iny                             ; $2A3055

   inx                             ; $2A3056

   dec     $0C                     ; $2A3057 | $0C + d=$0000 + dbr=$00 -> $00000C

      bne     loc_2A3048              ; $2A3059

   rts                             ; $2A305B


The address in the label and the first address in the comment are the ROM address of the instruction; the rest of the comment is commentary on the operand. So I guess now we have to find accesses to $000688 ($7E0688)...

MORE NOTES
sub_2A1963 appears to reset $5CF7
the one easily detectable cheat code is loaded to $5CF7 during the function sub_2A2F8B; the loading loop starts at loc_2A2FB6
the function at sub_2A1AA6; more specifically the code at $2A1B30, might be the code that loads button presses to $5CF7

Is that a password generator? I determined that sub_2A1974 is the one that fires away when a password is entered (I'm using a hex editor, but I know where the cheat checks occur because I know opcodes quite well), and thus is what I'm going for. It uses a few direct page variables and a lot of rotating and shifting to make the calculation... at least for a start. I'm analyzing that so I can crack the code and figure out how to trigger cheat ID zero (which stores a set of FFs to 7E2058).
