How convert XPloder / XPlorer to Game Shark

[misfire]

Check this out:

Xploder PSX Code Cryptor

From the README:

Even though I cracked the Xploder code encryption many years ago, I never
released an actual crypto program publicly. (I only put out the reverse-
engineered crypto routines but nobody used them to develop a program.)

However, here is xpcrypt, a simple console application which allows you to
decrypt or encrypt Xploder codes for PSX. Feel free to write a more
sophisticated tool. ;)

Cool, and thanks again for cracking them in the first place

I'm nearly finished implementing all four of the schemes in Majestic Porter, though I ran into a roadblock last night for a while, and ended up getting sidetracked.

OK, PSX XPloder decryption for all four schemes is implemented. I've updated the Majestic Porter thread, and added the latest version to the Downloads section, here:

http://gshi.org/downloads/Majestic_Porter.zip

However, I'd like to add support for encrypted N64 codes as well. Who cracked those (so I can give proper credit), and is the 4k encryption any different than that of the PSX (or is there even a 4k encryption for the N64 XPloder)?

And, luigi: these codes you posted...

...are encrypted with the 4k scheme. Majestic Porter can decrypt them for you, but you have to keep in mind that 70 for XPloder/GameBuster is the equivalent of D0 for GS, as is 90 the equivalent of D1. Take a look at the code types FAQs in the Library (and the wiki) if you need to.

Perhaps later I'll add an option to convert codes to GS format after decryption (change code types).

Great, thanks for the new version of the majestic porter Lazy Bastard

[Lazy Bastard]

No problem; thank misfire for doing the hard work

I'll update MP a little more tonight or tomorrow.

Oh, and as a note, what I said about Secrets of Professional GameShark Hacking wasn't true per se; they should have mentioned that all numbers should be treated as unsigned 8-bit numbers, and, more importantly, that operations were performed on the results of previous operations. The way the FAQ displays the three routines it has now, it seems a lot more like all operations are performed on the original code. This is what threw me off in the beginning.
