So, I've just discovered that mame allows this. You can play a game mirrored horizontally. I was trying to do this on a NES emulator but couldn't find any, and I also couldn't find a way to mirror my windows display. Does anyone know a way I can do it? The reason I want to do this is mainly because I think it would be a real novelty to play super mario 3 with the levels mirrored. edit: yeah, I tried playchoice smb3 on mame but it was lagging horribly. And I want to try this possibly on other games too.

some 3D games like mario 64 or goldeneye might be fun to play mirrored: http://www.youtube.com/watch?v=pHf4OGRQ918 it would be almost like playing the game for the first time, because it looks so different. i've read that if you have two screens, you can make the other screen mirror what's on the first screen, but there should be a way to do it with one screen too.

That mirror screen terminology is a little off, as all it does is copy the image. I thought about using an actual mirror to do this, but that isn't ideal.

hmm, this is kind of fun. switch the keybinds for L and R and quite a few games become playable without much extra difficulty

Exactly, I tried this in mame with wonder boy and the thought of playing super mario 3 that way made me close it and enter this research frenzy mode.

Well, I was able to accomplish it with a few lines of code modification to Bizhawk, but I don't know if it's worth adding as a feature. Any shader-based emu should be able to do it with a simple shader.

If you don't want to clutter the UI with mostly useless features, perhaps it would be enough to have support for it in an ini file or as a command-line parameter?

Any chance we can get your version or a command line/ini support as warp suggested? It would be really appreciated.

Less than 5 minutes of google search And after trying again half an hour later.

"Genuine self-esteem, however, consists not of causeless feelings, but of certain knowledge about yourself. It rests on the conviction that you — by your choices, effort and actions — have made yourself into the kind of person able to deal with reality. It is the conviction — based on the evidence of your own volitional functioning — that you are fundamentally able to succeed in life and, therefore, are deserving of that success." - Onkar Ghate

Thanks! That second one is exactly why it's hard to find it on google, it is NOT the effect that I want. It just rotates. I just tested the first one, and it seems to work fine :) edit: further testing. I hadn't tested with an emulator yet, so it seemed to be perfect. It isn't, there's a serious framerate issue...

Do it!

Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.
