Cannot find Master Code in AR12 format for 2-in-1 Sonic Advance/Sonic Pinball Party

[TokoyamiTheDark]

I just created an AR12 code that replaces regular-colored eggs with special-colored eggs in the Tiny Chao Garden in Sonic Advance from the 2-in-1 combo pack with Sonic Pinball Party since no one did it so far. But the thing is... I can't seem to create any working Master Codes for this - 6BCDAC23 D32498DA
(This code turns a regular Chao Egg into a Gold Egg in Sonic Advance from the 2-in-1 pack with Sonic Pinball Party. Works with VBA-H)

What can I do? If you need more exanples of codes I made in AR12 format for this game, just ask, though I am focusing mostly in codes for the Tiny Chao Garden...

ARCrypt can find and create master codes
download ARCrypt.rar

Thanks Lee4 for the nice code converting software. But it seems none of the Master codes or ID codes that shows when I load the ROM with ARCrypt are working with the code I created. What I mean is that my AR12 reckognise all of those Master Codes but the Egg modifier code doesn't seem to work under any of these master codes. (Oddly enough my newly generated egg modifier code works on VBA-H and NO$GBA...) I will try again and post my results when I'll be on my PC.

EDIT - It seems the Master Codes that AR Crypt creates are for the main menu only. In fact, both games, having a separate ID, needs a unique Master Code for each of them. That means one Master Code for SA and another one for SPP. So far the only ones who made codes for this 2-in-1 game are MadCatz but their codes are in CodeBreaker format... so I was wondering if it possible to convert their codes to AR12. If not, then I would need a tutorial for creating master codes for multiple games in the same pack...

you need another program to decrypt MadCatz codes

Ok. Now I copied and pasted one of the 2 Master Codes for this game and added spaces for CBACrypt to read them. It gave me this:

(M) Must Be On
993E41C6 E209
E56DC1CE CDBC
5CA99F7E 3D81

*Decrypted*
993E41C6 E209
00000776 000A
10897620 0007

993E41C6 E209 is the ID code or something, so it is unique for each game and always starts with "9". But my problem is, when I try converting the decrypted code with ARCrypt, I either get this:

993E41C6 E209
DC03DDF6 8E56
BC2529F5 1AF3 (still in CBA format despite choosing CBA to AR12 in ARCrypt)

or this, when the ID code is removed:

00000776000A
1199C2F0 4BC296CC

What am I doing wrong? It is like this for EVERY CBA code I try converting to AR12...


EDIT - It appears that 1199C2F0 4BC296CC is a Hook code, and when combined with 8D62E724 4637D69C, which is the ID code for the game (or is it for the main menu only?), I got a Master Code that is detected by my AR12! But the game Sonic Advance freezes EVERY TIME I load with with my AR12... Same for SPP, whose Master Code is
753BF7C5 DEF47D9E
8D62E724 4637D69C

Why does ALL of my GBA games freezes when I try loading them with codes converted from another device to AR12!??

*Decrypted* aka RAW format
993E41C6 E209 <--- this is CB/GSSP encryption key
00000776 000A <--- this ROM CRC
10897620 0007 <--- this master code

converting CB (RAW) master code to AR (RAW) format would be something like this
C4897620 00008401

Thanks Lee4. A mod can close this thread now that this problem is solved.
