I noticed the only thing that changes is the last 3 digits of the 4th group, increasing by 20, then 80. By the pattern of the way it increases, going backwards by that same pattern would result in 000 being 1x EXP. Obviously I can't go into the negatives so I can't for the life of me figure out how.

This isn't as straightforward as it looks because the code is changing instructions, it's looking for a code E0820000 which is add r0, r2, r0 (r0 = r2 + r0) and editing only the low bits, for example the x4 code is changed into E0820100 which is add r0, r2, r0, lsl 2 (this shifts r0 left twice for x4 before adding) what you want is the opposite, to do a right shift. add r0, r2, r0, lsr 1 which is E08200A0 (you can use an assembler, maybe more information is in the rom hacking thread) Since your code is only changing the last part of the instruction, the updated code should be 0.5x 5212194C E0820000 1212194C 000000A0 D0000000 00000000

Awesome! A 0.5x exp hack! But here is the problem with this hack, since the game is unbalanced difficulty-wise, when you fight Chaos Chimera, you are going to ragequit and turn your DS into a brick.

Thats why you change it to x16 for the end of the game, so by the time you hit the last boss, you are at an adequate level to kill him.

wooow cool if you have time can possibility create an similar code exp 0.5 but for pokemon Black and White please

is there anyway to make it x0.75? just to make it a bit harder, instead of twice as hard? or is that not possible the way the code works? thanks -edit. from the information yab provided, i think i 'made' (lol) the E and J versions of the 0.5x code too. http://gbatemp.net/threads/req-golden-sun-dark-dawn-difficulty-patch.269248/page-2#post-4711070

Looking at the posts above not really -- multiplying/dividing by 2 is the binary equivalent of multiplying/dividing by 10 in decimal in that you just shift the "decimal" point around and you have your operation (it is why the progression up there is 2,4,8,16.....). Now it would not be that hard to do it in operations (0.75 == 0.5 + 0.25 after all*) but that would probably mean stashing some new code in there, adding a jump, doing the operation and jumping back. Nothing major or even out of the realm of applying it in cheats but considerably more troublesome than tweaking the existing codes. *you should shift once, store the resulting value, shift again and redo the calculation for the new multiplier and then add results of the two operations together. If your cart has cheat enable/disable I would instead suggest just disabling the exp cheats every so often and having the same thing happen (mean of 1 and 0.5 is 0.75 after all).

sure, i thought about using the cheat every other time i play the game, just, of course it would be nice to not worry about it since you gave an outline of what needs to be done (thank you), it doesn't sound so hard... i will attempt to do it myself! thanks a lot
