bah dont get depressed by something like that, its just a statement of a user who doesn'T know what effort u put into this.
Of course i know doesn't meant it that way but people tend to forget this really fast so here i sum up:
* Emu Coding is hard , (boring?) work, the Coder does NOT get paid for it
* high skills are necessary like : Reverse Engenering unkown Hardware Plattforms ( Console to be Emualted) , Coding a Framework for Emulation this Hardware, Code Audio - Video Interfaces towards PC - Hardware & OS.
so -_-
This is extremely hard to do and as u might think progress is rather slow as most emu authors seem to work alone.
Slappy Comments like the one two above. Don't help much . ( Although i think comments like: go for it!! yeah do it! U can Do it! WOOHA i LIKE THIS! ... either help much but thats personal taste
