[Release] GDMenu Theme Manager v0.9a


New Member
Hey guys here is a pc app i made to allow you to change the look of the GDMenu theme, This app contains some themes i've made as well as some other people have made and it also contains the following:

  • GDEMU SD 1.10
  • GIMP2 Saves (Templates for making your own theme) - Optional
  • GDEMU Games List Generator (Created By Me Also) - Optional

This app is something i've been posting on the SegaNet discord and have had quite a few people test and has had quite a few updates adding features that were requested and the usual bug fixes and optimisations.


Console Preview:

This app also contains a built-in readme for anyone who wants to know how to use this but if you have any questions just let me know and i will be happy to answer them.

Basic Guide:
Choose a theme from the list to the right.

2. Click import theme.

3. Click save and save the .bin to the apps root directory (The name isn't important) and by default it will be named NEW-THEME.BIN.

4. Click scramble and it should bring up a separate app to scramble the bin file (Required) and enter the info automatically and bring up a save as window, if this doesn't happen close the scramble app and click save then scramble again and it should work.

5. On the save as screen navigate to the apps root folder and enter GDEMU_SD 1.10\data\files inside that folder you will see a 1ST_READ.BIN, Delete it and then click save and it will ask you to overwrite the file even though it's been deleted so just click yes and it should save the scrambled file.
Now close the scramble app and navigate to the 'GDEMU_SD 1.10' folder and launch the 'GDEMU_SD.exe' which is the GDEMU SD Card Maker 1.10 app.

6. Insert your GDEMU sd card if you haven't already and select it on the GDEMU SD Card Maker 1.10 app and your games should appear, now simply click Save on the GDEMU SD Card Maker 1.10 app and yes to customize and then simply click Done and let it apply the changes to your sd card and the new theme should be applied and you can close both applications and eject your sd card and test it out in your dreamcast.
