Sources say it is V6.

Fat16 or fat32?

Edit:
compiled v6 is missing from here: http://krikzz.com/pub/support/master-everdrive/v1/os-bin/

If it is .sms it should be fat16, if it is .mso it should support fat32.

I'm guessing 16. Isn't this the same source we had already some years ago?

Well I may be wrong, this is just a quick scan through on my phone.

#define OS_VERSION 6

fatOpenDir(u16 entry);

Looks like V6 with FAT16 to me. The previous version at http://www.smspower.org/forums/13347-MasterEverdriveSources was v4.

Try this, it should be the latest one: http://krikzz.com/pub/support/var/OS-edmd-sms.zip

Many thanks to krikzz for those sources :)

u8 fat_load_dir(u32 entry);

FAT32!

I didn't find the version number but it seems to have all the info needed. It's a bit messy, possibly due to having bits of other things in there, but broadly it seems possible to build on quite easily.

Fantastic! I hope Someone will build a totally new interface suitable for both gg and sms using those sources! Maybe we can talk about that in a New thread :p

You mean something like what the attached patch does? Dunno if this patch will work as-is. For the previous patch I ensured that the checksum is the same as before.
os-v9-2.ips (31 B)

Something that will automatically works with both gg and sms when flashed on the everdrive Without palette problems. We (me and zeus) will test your patch ASAP, Thank you :)

I'm not committing to making anything but I think the loader could:

- load some graphics (eg screenshots/box art) during browse, maybe on pause, from the filesystem - would not be pretty though
- have some music :) Wii Shop demake anyone?
- remember your "favourites" and also recently loaded games
- tell you what game is already loaded
- have a search feature
- ratings
- cheats lookup, possibly with Game Genie patching (I'm not sure what the X7 does here?)
- Upper and lower case text :)
- Perhaps some customisation from config files (colours, localisation)

All except the actual game loading would be possible to do without loading as "os". Another thing that ought to be possible is a filesystem library for homebrew that might want to read and write the file system.

I agree with everything!

Zeus also tested the new ips patch and it works fine for both sms and gg! Thank you Calindro!!
