Hello, I've been trying to get shrunk GDIs to work on my SD card in order to fit more games without swapping. The SD card I'm using works fine when I use non-shrunk images, but if I use either a pre-shrunk version or one that I created through gdishrink, the same thing happens no matter what game I try:

1. A static dreamcast logo shows up instead of the boot animation.
2. The bios menu fades in instead of the game.
3. Nothing is in either the 'Play' or 'Music' menu options.
4. I have to turn the dreamcast off/on to get back to the GDEMU menu.

I've tried both GDMENU and multiple versions of OpenMenu, and used both the upstream and forked version of the SD card manager. The SD card I'm using is a SanDisk Ultra 256GB (tried both 32k and 64k cluster size), and I have a GDEMU clone installed.

So far I haven't found much information about this problem aside from a post on Reddit:
https://www.reddit.com/r/dreamcast/comm ... nking_gdi/

...as well as an issue on the SD Card Manager GitHub repository:
https://github.com/sonik-br/GDMENUCardManager/issues/37

Has anyone else encountered this issue before?

Did you get these gdi files from here? Or did you shrink them with gdmenu manager?

After much ado ,I have them working mate.
Notepad was not saving the ini file from my tablet pc.
Once I edited and added the extra line listed above on my laptop all is well.

Seems bizarre that the image check is not disabled by default , I have a clone with the latest firmware so it was necessary to add it manually.

Glad to hear you have them working. Enjoy the games.
