Dreamshell compatibility - SD v HDD

Post#1 » Wed Sep 27, 2017 4:06 am

So I recently found this list compiled by pcwzrd13 which lists Dreamcast games which are supposidly compatible with Dreamshell and the settings needed to run them:

https://docs.google.com/spreadsheets/d/ ... edit#gid=0[/url]

Buttttt when I run GDI files from my SD card using the suggested settings they rarely boot. Is this because the SD card has different compatibility to the HDD?

Additionally, I've followed the steps in the guide to making .iso and they rarely boot either. I can download other people's .iso and play them with no problems.

Can someone advice me how to get the games on that list running from SD?

I assume you're using the serial port SD card reader? This list is compatibility for the IDE mod. The SD card reader has very low compatibility in comparison.

That being said, you can increase compatibility by optimizing the GDIs using the utility in the ISO Make Pack from here. Just copy the 'sys' folder and the 'optimize_gdi.bat' file to the same directory as the GDI, run 'optimize_gdi.bat' and wait for it to finish.

Yeah I am, that answers my question - thanks! What's the reason for low compatibility; is it because of the slow transfer speed?

Fantastic tip - thanks for that! 8-) :mrgreen: Edit: darn, didn't help, still can't get Midway Arcade Vol. 1 to boot! Thanks anyway.

Yup. There may be other reasons as well but that's the main one.
