Code Issues Releases Activity
nxdumptool/source/core/nxdt_utils.c
Pablo Curiel 04abb342bb Small code refactor (part 3). 
* Both gamecard header and decrypted CardInfo area are now retrieved upon gamecard insertion. LAFW version is checked against the CardInfo LAFW version right afterwards.

* Expanded GameCardStatus enum to add NoGameCardPatchEnabled and LotusAsicFirmwareUpdateRequired values.

* Updated utilsReplaceIllegalCharacters() to perform replacements on a per-codepoint basis, which means that invalid multibyte UTF-8 codepoints can now be replaced with a single ASCII underscore.

* Updated utilsGeneratePath() to truncate path elements that exceed 255 UTF-8 codepoints (safe limit for FAT and NTFS filesystems).

* Heavily simplified core logic in title functions by using newly defined TitleStorage elements (which hold the NCM database/storage handles, a TitleInfo array and a title counter) instead of the old, global index-based methods.

* Simplified background gamecard title thread logic by always returning duplicated TitleInfo data to the user.

* Update title API to account for the previously mentioned changes, including functions to free duplicated title data.

* Fallback gamecard filename string now also holds the gamecard package ID whenever possible.

* Implemented HDCP patching for Control NCAs.
