Help in implanting the "Lets Go" tile into SYZ

I am developing my very first hack. Althought not very original as most people have made this attempt already, I would like to make my own version of Sonic 1 Beta. Using Esreals Sonic Editor, I was able to complete alot of the stuff that program is capable of doing for Sonic 1, however, there are somethings I haven't been able to do in that rom and that is to implant some tiles. For example, we know the "Lets Go" sign tile (8x8) for SYZ is in the Rom, but what I wanted to do is get that tile and have it placed into SYZ level. I know Soned can do this if its a savestate (although I'm new to the program and hasn't been successful in saving it into the savestate for reason I don't know why :blink but I would like to have this hacked attempt done on a rom and not on savestate. If anyone can assist me on this attempt (along with hoping I made sense) I'd really appreciate it.

Just let me know what you guys need ^_-

 

I thought I remember seeing someone doing a project like that, just didn't know for sure along with who was doing it ;_;

Could I still continue with my idea though, only I would be trying to figuer it out myself cause I like the idea still and its good practicing in this stuff no? o.o

 

Thanks. My first attempts ofcourse won't be as great as the ones you guys here make but its still worth the experience. Its stuff like what you showed me just now along with some of the stuff I've seen from .hack//zero I would like to learn how to do in hacks ^_^

Well, unless anyone else has something to say, I think that's about it, the staff here can lock this if they want to or not o.o
