Can anyone help get me up and running?

Post by Matt Underwood »

Hey guys, I've been having a bear of a time trying to get ScummVM working on my Dreamcast with a MODE. I've followed these two different guides:

https://docs.scummvm.org/en/latest/othe ... mcast.html
https://www.dreamcast.nu/en/create-scum ... dreamcast/

As far as I can tell I've followed them to the letter and I've also tried some variations of them to try and get it to work.

My problem is that the cdi loads up to ScummVM, but it doesn't detect the games I've included.

I really have no idea why this would be and I'm now starting to wonder if it has to do with the version of ScummCM plain files (2.5.1) or of BootDreams(1.0.6c) that I'm using. Does anyone have any insight or some recommendations of best overall versions?

Here is the folder structure I'm using right now. Perhaps I am still messing something up here:

This is only the setup that I've tried most recently. I saw someone saying on here that they use a dummy file so I was trying that.

Anyway, I would greatly appreciate any help you can give me. Thank you.

Not used a MODE, but on my Dreamcast to burn a CD-R, I used the following Linux script:

#!/bin/sh
dd if=/dev/zero bs=2352 count=300 of=audio.raw
cdrecord dev=/dev/cdrom -multi -audio audio.raw
cdrecord dev=/dev/cdrom -msinfo
mkisofs -l -d -relaxed-filenames -C 0,11702 -o tmp.iso cd-image
( cat IP.BIN ; dd if=tmp.iso bs=2048 skip=16 ) > data.raw
# Need to use -xa, NOT -xa1 to ensure that 2048 byte blocks are used.
cdrecord dev=/dev/cdrom -multi -xa data.raw

Oh cool, I will definitely try that. Do I need a specific version or anything? Thanks.

Not really. I think it should work with most relatively recent versions of cdrecord, though be careful with -xa vs. -xa1 as that depends on the version.

This is based on the instructions from Marcus's website (He is the original DC porter):

i think i can help
starting from the 2.5.0 release, the games detect routine has changed

try this :
- add a PLUGINS directory in your files folder, and put inside both the plugin/s required (SCUMM.PLG in your case), and the DETECTION.PLG file

your folder structure should be :
ip.bin
scummvm.bin
000dummy.dat - optional
atlantis (directory with gamefiles)
PLUGINS (directory with both detection.plg and scumm.plg inside)

This did the trick. Thanks very much!

I ended up writing a new guide for this with lots of updated info.
