E1	8-bit different-from trigger	E1XXXXXX 00YY Activates next code if address 80XXXXXX is different from YY	Gameshark 2.2(?) and higher.
E2	8-bit less-than trigger	E2XXXXXX 00YY Activates next code if address 80XXXXXX is less than YY	Gameshark 2.2 and higher.
E3	8-bit greater-than trigger	E3XXXXXX 00YY Activates next code if address 80XXXXXX is greater than YY	Gameshark 2.2 and higher.
D0	16-bit equal-to trigger	D0XXXXXX YYYY Activates next code if address 80XXXXXX is equal to YYYY	NA
D1	16-bit different-from trigger	D1XXXXXX YYYY Activates next code if address 80XXXXXX is different from YYYY	Gameshark 2.2 and higher.
D2	16-bit less-than trigger	D2XXXXXX YYYY Activates next code if address 80XXXXXX is less than YYYY	Gameshark 2.2 and higher.
D3	16-bit greater-than trigger	D3XXXXXX YYYY Activates next code if address 80XXXXXX is greater than YYYY	Gameshark 2.2 and higher.
D4	16-bit universal joker	D4000000 YYYY Activates next code if the button presses equate to YYYY	Gameshark 2.41 and higher. Needs a button chart
D5	16-bit codes-on trigger	D5000000 YYYY Activates all codes if buton presses equate to YYYY	Gameshark 2.41 and higher. Needs a button chart
D6	16-bit codes-off trigger	D6000000 YYYY Activates all codes if buton presses equate to YYYY	Gameshark 2.41 and higher. Needs a button chart
10	16-bit incrementer	10XXXXXX YYYY Increments value at address 80XXXXXX by YYYY	Gameshark 2.2 and higher. Use with a joker
11	16-bit decrementer	11XXXXXX YYYY Decrements value at address 80XXXXXX by YYYY	Gameshark 2.2 and higher. Use with a joker
20	8-bit incrementer	20XXXXXX 00YY Increments value at address 80XXXXXX by YY	Gameshark 2.2 and higher. Use with a joker
21	8-bit decrementer	21XXXXXX 00YY Decrements value at address 80XXXXXX by YY	Gameshark 2.2 and higher. Use with a joker
C0	enable all codes trigger	C0XXXXXX YYYY If value at address 80XXXXXX is equal to YYYY, enable all loaded codes in game. Affects all codes, not just the one this line is used in.	Gameshark 2.41 or higher.
C1	codes-on delay	C1000000 YYYY Delays codes from being on by YYYY time when game starts. 4000-5000 should give 20-30 seconds.	NA
C2	copy memory	C2XXXXXX YYYY 80ZZZZZZ 0000 Copy YYYY bytes from 80XXXXXX to 80ZZZZZZ. Could be used for copying large sets of complex character stats from one character to another, like working-magic-only, if serial repeater won't work	NA
