Maybe someone should just post a link to Nemesis's guide just to simplify things.

Don't look at me! =P

Assuming you're talking about Sonic 2 for Genesis, just hack this into your ROM and it will bypass the checksum routine...

Edit: Forgot there are 2 versions of Sonic 2. If that doesn't work, let me know and I'll get the other ROM and make a new "Checksum killer".

Amongst the downloads on that site was a decompiler and recompiler...

Problem is there in another language and from what i worked out when i decompiled it it came out as a very small bin?

I'm much confused as to how to work it and if it is working properly is this .bin ment to be the outcome?

There are a couple of tools that can do it, if you happen to be using ESE II it was a checksum fixer built in, if not get Fix Checksum from the downloads section at Sonicology.
