Hi,
did you already integrated the fix for the deleting bug when you remove a game ?
Posted by AllWIIdUP:
Looking at the WBFS alloc and free functions I noticed an off by 1 error, that likely frees the wrong block.
in libwbfs.c:
CODEstatic void free_block(wbfs_t *p,int bl)
{
+ int i = (bl-1)/(32);
+ int j = (bl-1)&31;
u32 v = wbfs_ntohl(p->freeblks);
p->freeblks = wbfs_htonl(v | 1freeblks);
p->freeblks = wbfs_htonl(v | 1wlba_table); // bl = info->wlba_table
if (iwlba)
free_block(p,iwlba); // should have been free_block(p,iwlba - 1);but since "alloc_block" adds the +1 then "free_block" should have the -1, otherwise someone else might introduce the bug again, if the use free_block in another place since both block functions are used for "wlba_table".

@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.+1 -
@
SylverReZ:
They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

Nothing special about it other than it's more comfortable than the Lite+1

@SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme -

A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."+2 -

anyways, we need to re-normalize physical media+1
if i didn't want my games to be permanent, then i'd rent them -
@
BigOnYa:
Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

@BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.
The issue is DRM -
@
cearp:
You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60
