PC Engine CD and Sega CD Games

[azvarel]

Hi guys,

I'm going through a major stalemate regarding my PC Engine CD and Sega CD games.
I have long had your romsets tidy in the following situation .iso and .mp3, in addition to the .cue files
For some reason the emulators do not read MP3 files, and should read, since many of the
Recalbox users run their roms on microsd cards, and few use a HDD to make the most of games.

I will cite as an example the PC Engine CD game

4 in 1 Super CD

The cue / bin files have 504MB
While
The iso / mp3 files have 53,5MB

An absurdly big difference, and that would fit a lot more games to play.
Can you think, why both games, that you will not even play? Or if you finish the game delete and put another, but I do not think.
In this way, game overdue, I go to another game and the others who play with me have that game always available, without loss of time to copy the roms.

Already in Sega CD games, the game even runs through the .cue/bin but the audiotrack in MP3 does not work

Example .cue file of the Final Fight game

  TRACK 01 MODE1/2048

As far as I know, the emulators don't support mp3 files, so try opening an issue on the libretro ports for picodrive and/or genesisplusx (I don't remember which one is the segacd emulator), same for pcecd.
Usually the cue files point to other .bin files wich are really just .wav files with the extension changed, thus the size difference to .mp3.
But I might be wrong as well XD

Making the method that @acris put yes, but it is not what I want, I think of the size of the files the probability of implementing the isos with mp3, to gain more disk space.

Particularly I do not know who to ask, it is for the recalbox group if you have to implement to run iso / mp3, or for the libretro group and then you get them.

I believe that this is of paramount importance, remembering that users have space limitations due to microsd.

@azvarel
for the PC Engine CD emulator refer to:
https://github.com/libretro/beetle-pce-fast-libretro/issues

for the Sega CD emulator refer to:

• Picodrive
  https://github.com/libretro/picodrive/issues

• GenesisPlusGX
  https://github.com/libretro/Genesis-Plus-GX/issues

Although they might tell you to ask about it further upstream as well.

@paradadf
thanks.

@azvarel You must use the CHD format for gaining some place with PCE Games. Get CHDman and convert your games
