* 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.
