Sega CD Games Won't Launch
-
@lostless There are many versions of SegaCD BIOS files. Maybe you don't have the right BIOS files for the ROMs that you're trying to run.
-
@lostless I'm running on a Raspberry Pi 4 with 4 gb of RAM. Here's a screenshot of my BIOS folder. Does it look like I have the wrong names on BIOS files? I do understand there are two separate Sega CD emulators that take two separate BIOS files.
-
@iandaemon I just posted a screenshot of my BIOS folder below. I thought I had the main BIOS files for the two main SegaCD emulators based on what I've read, but maybe not.
-
@jmiller820 pretty sure the bios file names have to be lower case.
-
@zering Just renamed them to be lowercase, but unfortunately getting the same result.
-
One other detail - some ROMS when I try to launch them just go immediately back to the games list. Other ROMS actually do seem to try to load but get on a blank/black screen, and are stuck there until I use the hotkey to get back to the games list myself. All of my other emulators and ROMs are working, so this issue is definitely unique to SegaCD.
-
@jmiller820 what games are you running using which emulator?
-
@zering Here's my ROMs list. I haven't done anything to specify which emulator runs which game, but my understanding is that it defaults to lr-genesis-plus-gx.
-
@jmiller820 lr-genesis-plus-gx won't run the full Sega CD catalogue. It doesn't support CD32X games or multidisk games. Have you tried picodrive? That might partially resolve your issue.
-
@zering how do I switch it to run picodrive? I was aware of lr-genesis-plus-gx not running certain things, but I thought it would at least run SOME of my ROMs. It hasn't run anything.
-
@jmiller820 You launch a game, as it launches a small window will appear, press a button on your controller to open the runcommand menu where you can select a different emulator.
-
@zering Success! Haven't tried everything but picodrive is working on at least the first couple of games I've tested! So I guess my problem was specifically with the other emulator, or the BIOS for it.
-
@jmiller820 Probably both. Most of your roms aren't compatible with lr-genesis-plus-gx. Anyway, glad it's resolved.
-
@zering I really appreciate your help! I'm definitely learning as I go.
-
@jmiller820 We've all been there. As a matter of fact I had the same issue, I learned about BIOS because I wanted to play Snatcher on Sega CD.
-
@zering Snatcher is one of the games I'm looking forward to playing! Did an English language version of Policenauts ever happen? That's another one I wanted to try (I know that's for PS1).
-
@jmiller820 Yes on PS1 and Saturn. You'll have to find a pre-translated ROM or patch it yourself.
-
@zering found it and it worked! Now the only challenge will be finding time to try to play through Snatcher and Policenauts.
-
@jmiller820 They're only about ten hours long.
-
@zering Ten hours? I've been finishing Snatcher for twenty years. XD
