Does the new dol have NTFS support?
No, it was added by fix94.

also is there arg support to be used as Wiiflow or PL plugin?
No, argv parsing has to be re-implemented too.

Edit: Also is ogg support avaible in Sega-CD too, I would like to convert the huge waves to gain some free HDD space
Thanks :)
Yes, vorbis format is only for Mega-CD/Sega-CD audio tracks.

Did you use VBR or constant bit rates 128
also can you please post a sample cue file with oggs :)

Fix94 updated the plugin dol, now it has ogg support and ntfs support with auto mount/unmount feature

I have almost the entire US set so I imagine this would make a huge difference to storage space on my HDD. What tools did you use to convert, Turborip? All mine are in BIN + CUE format.

Dear friend the good news is that you don't even need .cue files anymore :)
This is beneficial in another aspect. genesis plus gx file browser now only shows 1 .iso file for every game and not .ogg file or .cue files, so you can have all sega cd files in one big common folder. Only thing left for GPGX to be perfect, is to have CD disc-art instead of megadrive cartridge artwork, showing next to the games. Oh and 32X oneday haha.


I only use .iso & .ogg files and i rename the according to the readme.pdf (page 6, text in the box).

This is the procedure, step by step: 1. I download the games as .iso & .mp3 files.
2. Then i convert the mp3 files to .ogg with Freerip. (.ogg options for that program are simply set to stereo and quality=4, i didn't tinker any other settings, see attached pic :) )
3. Then i put the .ogg and the .iso files in the same folder and 4. if i need renaming the audio files i do it with Bulk renamer. Thats' it.

I'll post a pic of my Sega CD folder, attached to this post, to give an example :)

P.S. FYI, .ogg files are also supported by WiiMednafen for PCE CD games. The process is mostly the same as here, with the only difference beeing that WiiMednafen requires a .cue file. If anyone wants help with that, i'll post a sample pic and a sample .cue file of a PCE CD game.

thanks for your help, I've already tested oggs yesterday, and all worked fine
I used nero "encode files" Tool to make 128 (CD Quality) oggs which turned out to be less than half the size of 50% VBR
As for the cue file I used ImgBurn cue maker
I have 1 cue for each game which makes life easier when it comes to wiiflow plugin and since all works fine I'm keeping them there since in case I want to delete them I'll need to rename all the oggs.
Anyways using some tiny free tools for ogg conversion can cause trouble, I tried to batch convert the waves to oggs using a free tool and found out that all oggs were corrupted,
so i used a data rescue kid to restore the deleted waves and then used nero to finish the job

    "very dark scenes are more common than very bright scenes" not in the games i play

  • The Real Jdbye @ The Real Jdbye:
    really have to buy the top end model to get a tv that doesnt have any of those compromises and that would've had more dimming zones too but i am not made o money

  • The Real Jdbye @ The Real Jdbye:
    @Julie_Pilgrim "very bright" is essentially pure white

  • The Real Jdbye @ The Real Jdbye:
    pure white doesn't show up all that much it's mainly when looking at a bright sky

  • The Real Jdbye @ The Real Jdbye:
    and if the clouds in the sky have slightly less definition to them because i turned on the contrast enhancer who cares

    i can't tell the difference

    but i can certainly tell the difference with black crush if i'm watching a scifi movie and i can't see wtf is going on

  • SG854 @ SG854:
    Human vision is logarithmic, it's not linear. And nits doesn't tell the whole story of perceived brightness. OLED'S look brighter then LCD's even when both are set to the same nit values because of the higher contrast ratio on OLED's

  • SG854 @ SG854:
    OLED's have a 3D look

  • kenenthk @ kenenthk:
    Charging port is more likely to fry up or battery fail before the display tbh lol
    Gift
  • The Real Jdbye @ The Real Jdbye:
    "And nits doesn't tell the whole story of perceived brightness" it's not about perceived brightness it's about all HDR content in TV and movies being mastered for 1000 nits so it doesn't look right with anything lower, it's also about dynamic range

  • The Real Jdbye @ The Real Jdbye:
    "OLED's have a 3D look" no they don't lol
    Gift
  • SG854 @ SG854:
    As an owner of a OLED and you saying that you never seen an OLED I think I know what I'm talking about lol. I'm not talking about 3D as in 3D glasses. I'm talking about depth and pop in the picture

  • kenenthk @ kenenthk:
    I mean to be fair og vitas are still kicking and not many have suffered from pixel bleed and they're going on nearly 10 years
    Gift
  • SG854 @ SG854:
    OLED's can get away with a lower peak brightness and still provide punchy HDR because of their contrast ratio. Like I said human vision is logarithmic. The higher the peak brightness the diminishing returns in perceived brightness.
    Gift
  • kenenthk @ kenenthk:
    Just get 5 years enjoyment out of it until Nintendy releases something and everyone forgets about switch games lol
    Gift
  • SG854 @ SG854:
    @The Real Jdbye Oleds hit around 750 nits nowadays. The difference between a 1000 nit and a 750 nit isn't huge. It's only about a 4% increase in perceived brightness. Not huge at all. You'll need at least 2000 nit displays to notice a bigger difference.
    Gift
  • SG854 @ SG854:
    Read this thread it explains it. 1000 nits is not a huge jump from 750 the LG OLEDs can hit. As I said human vision is non linear.
