GP32 Long Filenames

[fdave]

Good news, I managed to get some long filenames onto my SMC! I used GPDrive.

And just like in DOS they appear as AFTERBU~1.SMD, so can you tell me, for long filenames how can I read out the full filename on the GP32 to display in the rom list?

Presumably this is a FAT extension thing

look at the frodo source it shows long filenames

you'd have to change gp32's bios to support long filenames i think..
sry, but if it would be easily possible someone had already done it

Edit: fogive me for what i'm writing ^^

you talk shit


its a thing of the smc libs

also the Sid Player seems to support LFN's in the same way as Frodo

You need to be able to read the vFAT tables to get the long filenames. gpDrive puts all the vFAT stuff on the SMC (well Windows does it for you).

You don't need to make any changes to the Bios at all to do this but you will not be doing this if you use the GamePark SDK for all your file access.

I know of a few bits of working code to READ long file names that are derived from the Samsung SMC code, they write using the short names. Before anyone asks, I don't have the code anymore. Not looked at Frodo but I would guess it does long file names in the above way so should be a good code sample to look at .

crikey - all sounds a bit involved! writing your own FAT reader from scratch I mean

Is there any simpler way to just get the extra FAT info, using the GamePark functions?

Not that I know of, Squidge is very good on this sort of stuff .

Let me have a dig in my code dump and see what I have that may be of use.

if it's up to the smc-lib, wouldn't it be possible to use ext2(ext3), too? :rolleyes:

It is theoritically possible, but that could depend on ext filesystems specifications. Any nix guru outta there?

I've formatted a 1.4mb floppy with ext2 before if that's what your asking (don't ask why )

No idea about ext3.

I have a better (quicker) idea, add zip support and read the long filename from the zip?

gp32linux should be able to read ext2/3 filesystem.
@the_Diabologic: What do you need it for?

Good idea, but if you have a lot of zips, it could take a long while to display the menu. It's one of the performance problems I had with BOR. Eventually I cached the directory table, but you can't do that if you have multiple zip files to process.

Unless of course you save the output and give the user a "refresh list" type kinda button.

More or less like Little John GP. The difference is that LJ uses the Nestoy database to get roms names instead of reading long filenames.

Thing is I already have to rename my romset for the XBox because of the 42 character limit. I thought that was bad enough, but having to rename it to 8.3 is just crazy! It'll never work for one thing - all the duplicate filenames
