Mez's Codes...

[lee4]

Earthworm Jim (U) [Sega Genesis]

I completely avoided testing out Galoob's Infinite Health code because it had that extra note.

[Infinite health (may cause graphic errors) - GC3C-JA9W]

Figured that's why VisitntX had made a different code.
Since VisitntX's code did not work at all for me, that's why I decided to make my own code.
My code works for almost everything, but when a crow would pull on your head you would still take damage.

After finally trying out Galoob's version, I know now I wasted all that time for nothing...
Their code works perfectly, and I seen no graphic errors at all.

Maybe if someone has the cartridge and real hardware to test VisitntX's and Galoobs code, it would be best to remove Galoob's note, and delete the code by VisitntX.

Anyone have the real cart and original hardware?
I used to have both, but that was back during my childhood.

you should PM VisitntX and post in his Genesis thread about problem with his code.

thanks for make codes for Earthworm Jim 2 but, it is impossible to make a new code so the old lady will not hit Jim with her purse as if you are try to go the upstair by using a stair lift

Alright, I'll take a look at it.
That part is pretty easy to get past, you use the right and left buttons to slow down or speed up the lift.

Indiana Jones and the Last Crusade (U) [Sega Genesis]

Pick Up Torch From Anywhere
004D5A:6002

An accident code while trying to create the same code I did for the Game Gear version, to make the screen never dim.
Only tested on the very first torch soon as you start the first level, since I suck at this game.

Edit:
Adding these 2 Action Replay codes to the above code will cause your score to keep increasing, since your picking up 15 point torches multiple times:
Torch Does Not Go Away After Picking It Up
FF97E2:0000
FF97E7:0001

A score of 30,000 grants you an extra life.

[47iscool]

Nice codes Mez! Those character swaps are nice.

[Mezmorize]

Thanks!
Just messing around, FCEUX is pretty awesome.
Right now only using 2 opcodes, I'm not even sure what opcode is used to always branch.

[rimsky82]

IIRC, there is no opcode for always branch for the 6502.

IIRC, there is no opcode for always branch for the 6502.

Thanks.
Cant say I've done any research into the processor, I've only been using VisitntX's opcode list:

Nice codes! They actually work on SMB1 cart game only too. You can actually add these GG codes also in Super Mario Bros. (World)'s database page http://gamehacking.org/?game=31010 because they works on it too, not only on Super Mario Bros. + Duck Hunt game.

Also, I want to ask you when the codes from this thread will be added in database? Except for the ones on Page 1, for all of your codes since page 2 until now, forum says nobody was added your codes in database yet.

Actually I've add most of these codes to "Super Mario Bros." alone since they works on it too.
