How do I add voice to lr-O2EM?

steptoe

Did some digging and found this in the docs for the linux version of o2em

If you wish to use Voice emulation for games like KC's Krazy Chase, create
a directory called VOICE in the directory where you have O2EM. Download the
voice samples and unzip them into the VOICE directory. There are two sets
of voice samples, mainsamp.zip which is the main voice samples and sidsamp.zip
which are the samples used by the game Sid the Spellbinder. You only need the
Sid samples if you want voice in that game

You will need to find the o2em folder once you have installed the emulator via the install script and run it once to make sure its running and all needed folders are set up correctly. I'm guessing it will be put in the same place as the other emulators that have been installed

I can find the install folders for other emulators, but not o2em. Any idea where it is?

I can't find anything solidly documented either way, but I don't think this is a feature currently supported in the libretro version. In it's earliest form it was noted as not being possible and looking through the commits, it doesn't seem like the ability was ever added.

@mediamogul That's a shame. Thanks for your time, everyone.

OK, commenting on a pretty old post, but as a lover of the O2 (I spent so much time playing with it from the ages of 9-11 or so) I thought I would detail what worked for me.

In \retropie\bios\ I created a folder called "voice" and then placed the unzipped voice samples into that folder.

The sample zips are called "mainsamp.zip" and "sidsamp.zip".

That did the trick! I tested "Type and Tell", "Sid the Spellbinder", "Attack of the Time Lord" and "KC's Krazy Chase" and they all work.

Cheers!

@speedyrb pretty neat! Looks like support was added this past year:

@quicksilver Cool beans!

They broke audio in late November and haven't fixed it yet. Best to sync to commit c039e83. Works best and doesn't have the funky pitch issues introduced.

Still, has lots of audio issues (pops and such), but speech does work.

Another option (or complementary emulator) is lr-mess with unofficial, modern scripts. Seems to work best (actually, very well) for most of the voice games (except Sid & Turtles). MESS requires separate ROMS/Voice samples and headache to install, but once running is quite good.

lr-o2em: Has options to swap L/R controller within options. Fast. Great in-app keyboard that resembles the O2/VideoPac layout. Easy to run. Has audio issues. Gameplay speed can be off a bit.

lr-mess: Much better audio, esp. voice. Some bugs with some games (eg. 4 in 1 Row won't launch). Can't swap controls. No in-app keyboard.

Using both and customizing each emulator to different games covers about 95% of everything. Games like "Turtles" don't run perfectly with either.

@roslof thanks for this, i always wanted the voices to work again, i just never looked into it more.

but now i have a little more to go on.

For Videopac/Odessey2 I added 2 lines in the section systems with >EXTRAS< that will install the system and patch the default loaders directly after that.
This way the default loaders will always loadvoice.
All games seem to work correctly with these patched loaders.

Would you like to test it for me?
(EDIT1: I forgot to test if the lr-o2em loaders are affected by the patch, I have to take a second look. Will let you know when it's ready !)
(EDIT2: The second commit should fix the issue in EDIT1 !)

@folly standing by. Just let me know.

FWIW, I'm not having issues with voice for lr-mess, except for two games that seen to have compatibility issues.

Turtles. No emu seems to handle voice properly here
Sid the Spellbinder. With lr-mess, it doesn't actually say the word to spell. lr-o2em works here though.

Otherwise, all voice seems okay to me with lr-mess (original scripts I tinkered with when @valerino first started with his lr-mess scripts).

You can try, It looks ok now.
