Redream setup

[dsquared]

Hello:

I have a question about how to set up Redream. I have installed it and have games on the RPi.

When I select a game, Redream takes me to a screen asking me to select a library. I select:
/home/pi/Retropie/roms/dreamcast
and exit and restart emulation station (also tried restarting Retropie) but the directory isn't saved and the game will not launch, and no games show up.

Anybody have any ideas of what is going wrong here?

Pi Model or other hardware: 4B+ 8GB
Power Supply used: Generic 5.1V 3000mA
RetroPie Version Used: retropie-buster-4.7.1-rpi4_400.img (updated all packages)
Built From: Pre made SD Image on RetroPie website: retropie-buster-4.7.1-rpi4_400.img
USB Devices connected: generic USB SNES controller & MS bluetooth keyboard & mouse
Controller used: generic (kiwitata) USB SNES controller
Error messages received: zilch
Verbose log (if relevant): N/A
Guide used: N/A
File: (File with issue - with FULL path): config.txt?
Emulator: N/A
Attachment of config files: https://pastebin.com/ECCpJe9z

I have a question about how to set up Redream.

How did you install it ? Did you use RetroPie-Setup to install the redream package or you installed it manually ?

... and no games show up.

Did you copy your disc images to the dreamcast rom folder ? What is the name of the disc files - they need to be in a certain format (file extension) for them to show up in EmulationStation and to be launched directly.

Thank you for replying. I installed the redream package from the RetroPie-Setup menu > manage packages > manage experimental packages > 40 redream.

I copied cdi files to the dreamcast directory:

/home/pi/Retropie/roms/dreamcast

(where they show up). For example: "Typing of the Dead, The (USA).cdi"

So far, it looks fine. If you launch the game from EmulationStation, it should be started automatically. If there's an error with the file or the emulator, it should be logged in the /dev/shm/runcommand.log file. Can you get its contents and post it on pastebin.com ?

@dsquared on a side note .cdi files are not recommended as they are quite frequently compressed (lossy) and or missing data. .gdi or .chd is a much better way to go. Although I don't think this is your current issue.

2. I tried a gdi file and it worked! My dreamcast collection is entirely cdi based. I guess I will have to replace them.

I installed based on a couple of YouTube videos. This

at about the 2:30 mark talks about cdi & gdi formats at about the 2:30 mark and says that the cdi format should work.

Looks like a .cdi image problem, probably that's why Redream doesn't load the game and pops up the library dialog.

@dsquared .cdi "should" generally work but also cause more issues than they are worth.
