No thanks. If the author doesn't care about Linux, I don't care about the program. I do make exceptions for work and essential programs, but UAE is none of them.
Oh, my God. Please stop this childish attitude.
"I don't like emulator because it doesn't have a key I use"
"so map it to something else"
"but gneeee gneeee it should be theeeereeee!"
"I need it to compile things inside the emulator"
"you can cross-compile them outside of it"
"but gneeeeh gneeeeh it's not the same"
"WinUAE GUI has things FS-UAE hasn't"
"You can run WinUAE on Linux using wine if FS-UAE does not fit your needs"
"but gneeeh gneeeh I don't like it and if coder does not consider Linux, I don't consider his program no matter if I can freely modify it as I wish"
and so on. Really, this discussion doesn't picture you very well. You'd consider stopping it.
