N64 Gameshark Encryption?

[Maq47]

I have Project64 1.7.0.49, and it uses Xploder/Xplorer codes, which are encrypted GS codes. I know the encryption scheme, but want a program that streamlines it. Anyone know of one? For those that don't know, the encryption goes like this (copy-pasted from http://doc.kodewerx.org/hacking_n64.html#xp_encryption) :

Encryption Algorithm
A0A1A2A3 D0D1
A0 = (a0 XOR 0x68)
A1 = (a1 XOR 0x81) - 0x2B
A2 = (a2 XOR 0x82) - 0x2B
A3 = (a3 XOR 0x83) - 0x2B
D0 = (d0 XOR 0x84) - 0x2B
D1 = (d1 XOR 0x85) - 0x2B
 
Alternate:
A0 = (a0 XOR 0x68)
A1 = (a1 XOR 0x01) - 0xAB
A2 = (a2 XOR 0x02) - 0xAB
A3 = (a3 XOR 0x03) - 0xAB
D0 = (d0 XOR 0x04) - 0xAB
D1 = (d1 XOR 0x05) - 0xAB
Decryption Algorithm
A0A1A2A3 D0D1
A0 = (A0 XOR 0x68)
A1 = (A1 + 0x2B) XOR 0x81
A2 = (A2 + 0x2B) XOR 0x82
A3 = (A3 + 0x2B) XOR 0x83
D0 = (D0 + 0x2B) XOR 0x84
D1 = (D1 + 0x2B) XOR 0x85
 
Alternate Method:
A0 = (A0 XOR 0x68)
A1 = (A1 + 0xAB) XOR 0x01
A2 = (A2 + 0xAB) XOR 0x02
A3 = (A3 + 0xAB) XOR 0x03
D0 = (D0 + 0xAB) XOR 0x04
D1 = (D1 + 0xAB) XOR 0x05
