Package: rhdndat
rhdndatfindsrhdndat.verfiles to check for romhacking.net updatesA version file is namedrhdndat.verand has a version number line followed by a romhacking.net url line, repeated. These correspond to each hack or translation. To check for needed updates to version file, if any patch version in the file does not match the version on the romhacking.net patch page, it presents a warning.rhdndat-rnrenames files and patches to new .DAT[1][2]rom names if it can find the rom checksum in those .DAT files and memorizes the checksum of the ‘original rom’ as a extended attributeuser.rhdndat.rom_sha1to speed up renaming in subsequent executions (in unix, not windows).To find the checksum of the original file for hardpatched roms, rhdndat-rn can support a custom convention for ‘revert patches’. Revert patches are a patch that you apply to a hardpatched file to get the original. These have the same name as the file and extension ‘.rxdelta’ and are done with xdelta3. I keep them for patch updates for cd images (since delta chd support is rare).rhdndat-rn will read a xml dat file or every dat file from a directory given, and ask for renaming for every match where the rom filename is not equal to the dat name proposed. It will skip the question if all the names proposed already exist in the rom directory, and not allow a rename to a existing file in the rom directory.Besides bare rom files, files affected by renames are compressed wii/gamecube .rvz files, .cue/.toc/.gdi (treated especially to not ask for every track), the softpatch types .ips, .bps, .ups, including the new retroarch multiple softpatch convention (a number after the softpatch extension), .rxdelta, .pal NES color palettes, and sbi subchannel data files.nes fds lnx a78roms require headers and are hardcoded to ignore headers when calculatinguser.rhdndat.rom_sha1to match the no-intro dat checksums that checksum everything except the header. This is problematic for hacks, where you can ‘verify’ a file is the right rom, but the hack was created for a rom with another header. A solution that keeps the softpatch is tracking down the right rom, hardpatching it, and creating a softpatch from the current no-intro rom to the older patched rom. For sfc and pce ips hacks that target a headered rom I recommend ipsbehead to change the patch to target the no-header rom.Requires xdelta3 (to process rxdelta) and dolphin-tool (to operate on rvz files) on path or the same directory.To check for updates if you have the version files:rhdndat romdircheck if there are any updatesTo rename files if you have the dat files:rhdndat-rn[--force][--exta78--extnes...]romdir xmlpaththe rom extensions should be all file extensions on the files you want to rename (see below for default)rhdndat [OPTIONS] ROMDIRROMDIR:Directory to search for versions to check.
