You don't actually have to know 6502 asm to modify NES games. To do some of the more hardcore modding a bit more extensive knowledge is required.

Also, I have no clue what an '.ips' file is.

An IPS file is a set of instructions to overwrite specific byte ranges in a file with different bytes. It's like a diff that can be patched into a ROM to result in a hacked ROM. It's generally much smaller than a ROM.

I would honestly not start with Game Genie modding just yet. Here is sort off a tentative list of how I would start out:

Sprites
Palette
Text
Game Genie

Anyway so far as decoding the Game Genie codes goes, you can just use the tool I wrote for it.

Also, I'm not too sure about the general attitude towards NES modding on this site, so if its a problem with everyone else, just comment on my site or PM me.

You could try using a modern emulator such as FCEUX or Nintendulator.

If you use nesticle, good chance is none of your programs will work on a real hardware. Use something a tad better like FCEUXD which has tons of crap build in. Then for more accuracy, do Nintendoulator and Nestopia.

Yeah, I just kinda used NESTCL 'back in the day' but FCEUXDSP is a much better tool.

ok cool, thts wut i have been using, do u mind trying to update ur tutorial on ur website for game genie encoding for FCEUX? or could u just tell me basic guidelines for what to do? im still tryin to get used to all of this code stuff but im slowly getting used to using it !

FCEUX has something like that easily found in the menus. Goto DEBUG and then GAME GENIE ENCODER/DECODER

Just go through the menus, you'll run into what you want eventually
