rewind problem on Sega CD

suzsuzuki

Hello guys,

Whenever I try to put rewind as default on main game menu or in Sega CD menu, rotroarch Sega CD starts with no rewind enabled. I need to enable manually on retroach menu after start the game.

I think it's a bug since Sega CD can support rewind.

Thanks

hum strange.
it's an emulator i've never tried however.
i mark to test it in my next tasks to see if i found something.
i may guess that it depends on something else (ie, if you set it in the config file, it's not taken into account because an other value is not set, while if you set it in the menu, it forces the other value - just a guess, but it may be something completly different.)

Well I tried to force rewind for Sega CD in some config files with no success.

I think it happens because in the past retroarch emulator for Sega CD didn't support rewind and recalbox team forgot to re-enable in some file... honestly idk.

nadenislamarre

you're right.

Define systems not compatible with rewind option

systemNoRewind = {'virtualboy', 'sega32x', 'segacd', 'psx', 'fba_libretro', 'vectrex', 'zxspectrum', 'odyssey2', 'mame', 'n64'};

i remove sega32x from this file.
Can you first confirm it works if you are able to do it :

1) via ssh, mount -o remount,rw /
2) edit /usr/lib/python2.7/site-packages/configgen/generators/libretro/libretroConfig.py line 39, remove sega32x
3) /recalbox/scripts/recalbox-save-overlays.sh

if not, confirm you're using rpi3, i'll build an update image for you.

outch, sega cd, not sega 32x.

If possible, make this line "systemNoRewind = {'sega32x', 'vectrex', 'zxspectrum', 'odyssey2', 'n64'};" by "deafult" in the next official 5.9 release ...thanks !!!

suzsuzuki

Thank you =)

I can test later today, now I'm at work.

suzsuzuki

Hey.. worked like a charm 😃

Thank you!

EDIT: btw you can do it with psx and virtualboy too since they also supports rewind. THe others I didn't test.

suzsuzuki

Someone could test rewind in others emulators?

{'virtualboy', 'sega32x', 'segacd', 'psx', 'fba_libretro', 'vectrex', 'zxspectrum', 'odyssey2', 'mame', 'n64'};

EDIT: fba_libretro and mame also supports rewind, The others I can't test.

EDIT2: Per my tests we can edit the line to:

systemNoRewind = {'sega32x', 'vectrex', 'zxspectrum', 'odyssey2', 'n64'};

Of course I really don't know if this line is really necessary....

Luiz, você poderia testar esses outros emuladores faltantes e ver se há rewind? Eu não tenho roms pra testar....
'sega32x', 'vectrex', 'zxspectrum', 'odyssey2', 'n64'

Luiz could you please test the rewind function in the others emulators? Thanks

nadenislamarre

noted. thanks.
can you confirm you tested all that ?

suzsuzuki

nadenislamarre

I tested all except:

'sega32x', 'vectrex', 'zxspectrum', 'odyssey2', 'n64'

Give me some time and I can test these ones...

nadenislamarre

ok, thanks. for the moment i've updated the list.
however, it's strange as parameter, i hope that retroarch works even if this parameter is true when the core doesn't support rewinding.

suzsuzuki

Ok I tested all the systems and the best option so far is:

systemNoRewind = {'sega32x', 'zxspectrum', 'odyssey2', 'n64'};

Considerations:
sega32x - Rewind ONLY works if you enable it AFTER you start the game. Can't be default on menu.
zxspectrum - Roms don't start if rewind is default. Needs to be avoided.
odyssey2 - rewind don't works. No difference if keep default on menu or not. Better avoid.
n64 - rewind don't works. No difference if keep default on menu or not. Better avoid.

All others retroarch systems is OK.

suzsuzuki I've tested only N64 (i have roms) and not works ...the N64 emulator appears to be not an Libreto Core , but an complete emulator and the rewind not works on it ...

nadenislamarre

thanks. i will update with your information.

nadenislamarre

by default, it's not a libretro core.
