Hey there- I noticed DrFuji replied to you already so there's probably not much need for me to. Basically, you should have a look at the various hack sections in ROM Hacking (namely the Hacks Showcase, Progressing Hacks and the Sideshow Showcase). Each section has a sticky thread, you should have a read of each, so that you have an idea of where your hack would fit.
I'd suggest reading the Sideshow Showcase sticky first- if you think your hack doesn't fit there, then next would be Progressing Hacks. (It's VERY unlikely that a hack goes straight into the Hacks Showcase).
I also recommend having a look at various hack threads in a subsection before posting- if you can see them, that means they were approved, thus they'd be a good basis for your own thread! :)
Threads have to be approved by moderators before they become visible to ordinary members in the Emulation section. Your submitted threads didn't meet the requirements as laid out in the rules so I didn't approve them. If you want your threads to be accepted in the future then I highly advise reading the requirements so you know just what to include.
