default hotkey combos list in libretro mame

mattress67

I'm gonna straight out ask the question, because frankly I'm tired in searching - and I've searched a lot!

I've got a PS3 controller - during my search on using shaders I came across the fact that the hotkey + M or hotkey + N would allow me to change shaders during game play to compare. I've used this combo to compare shaders in MAME during game play and it works great. That led me to searching for a list of preconfigured hotkeys for the PS3 controller. Yes, I've been to GitHub and have seen much info on the PS3 controller. Something good came out of that, I got the Bluetooth working but I cannot for the life of me find any list that include hotkey combos like the M, and N I previously mentioned and that combo does work well.

@mattress67 Looks like you want to check your /opt/retropie/configs/all/retroarch.cfg.

The combos you mentioned are input_shader_next and input_shader_prev.

I don't know any clear and organized list of all available combos, but the retroarch.cfg skelleton on RetroArch repository is a good reference IMHO.

Yup, buried in there was...

# input_exit_emulator = escape
# Applies next and previous shader in directory.
# input_shader_next = m
# input_shader_prev = n
# Hold button down to rewind. Rewinding must be enabled.
# input_rewind = r
# Toggle between recording and not.
# input_movie_record_toggle = o
# Toggle between paused and non-paused state
# input_pause_toggle = p
# Frame advance when content is paused
# input_frame_advance = k
# Reset the content.
# input_reset = h
# Cheats.
# input_cheat_index_plus = y
# input_cheat_index_minus = t
# input_cheat_toggle = u
# Mute/unmute audio
# input_audio_mute = f9

Thanks. It was "input_shader_next" that I needed. Without that, I didn't even know what to search for. This provided the "hotkeys" I was looking for as well as others. Still, you'd think they'd be a list.

I appreciate all the guides, videos and instruction on this and other web sites, but I've never had such a difficult time getting something to work. After a few weeks, I can say I'm almost there. Weeks! That's crazy!

@mattress67 please format your posts ;-)

put small logs in code blocks - see http://commonmark.org/help/ - and put large logs on a pastebin type site like http://paste.ubuntu.com/ http://pastebin.com/ or similar.

Your snippet above should be between one line with 3 back ticks in the start and another line with 3 backticks at the end. Like this:

This is my code block

Also in there is a turbo button function, but I can't get it to work nonmatter what I try to do.

@tmntturtlguy I believe I managed to get that to work but it's suboptimal. You need to keep holding the button while holding the one you want to do turbo on - so effectively you'll be holding two buttons at once.

I tried that too !
I couldn't assign fast forward to a single button (ie : R2 trigger), it had to be combined with select.
Problem is : if you have to maintain select+R2 for turbo, and say wou want to make an action ingame (B), that will hit the reset rom shortcut (select+b)...
Here I stopped my researchs, after accidentally resetting maybe 10 times :)

@sano Hm.

I'm not sure that's what I experienced. I think I managed to assign it to R1 in my case, but then I needed to keep holding R1 for Turbo to be in effect, which made it weird as I had to spend the entire game with R1 pressed.

But it was a long time ago.

@pjft
My bad, I mistaken turbo and fast forward in your post.

This is exactly how it is supposed to work. But you can optimize your fingers... :) Let me explain with an example:

L2 is the enable turbo button
Y is the button that makes the space ship shoot

Hold L2 and then hold Y, it makes your ship shoot continuously.

Release the L2 but keep pressing Y, your ship keeps shooting (Y still is on turbo mode).

Release Y, yor ship stops shooting (of course) and Y is not on turbo mode anymore.

Summing up: when you press L2 plus another button, the "another" button is on turbo mode and the you can release L2. Once the "another" button is released it is not on turbo mode anymore.

@meleu Oh! Had I known about that...!

@meleu Ugh. Of course. My apologies. I'll see if I can edit. Done!
