The Script can be modified to do this by changing the lines : The Database-headers can work with the Nt Mini so long as these fields, bytes 14 and 15, are set to 0. The Analogue Nt Mini supports NES 2.0 ROMs, but it has difficulty with the Miscellaneous ROM field and the Default Controller Type field, which were added after the Nt Mini was released in 2017. sav file, no-intro provides that information. Kid Dracula (Castlevania Anniversary Collection).nes will require Kid Dracula (Castlevania Anniversary Collection).sav file with a size of 8,192 bytes and a CRC32 of ABA5001B to work properly. These characters require Unicode support to display properly, so a renaming function is not provided. Japanese games will use Japanese characters if the original title was in Japanese, and likewise for Chinese, Korean and Russian games. If you open the XML file in a text editor, and I recommend Notepad++ for this task, you will find that each game entry has a name which will correspond to neither the ROM's GoodNES or No-Intro name (if the ROM is included in either set). The option "TRIM_UNKNOWN_DATA" can eliminate that data. Some NES ROMs come with some extra data at the end of the ROM which is truly junk information such as the date the game was dumped and the name of the dumper. nes file name extension, you can use a tool like Bulk Rename Utility to rename files with the. For unrecognized UNIF ROMs, you can use the option "MARK_UNHEADERED = 0" to remove all the UNIF stuff and leave it as a bare binary. If you wish to preserve your UNIF-formatted files, make a backup copy first. The Script will calculate the hash of the ROM without the UNIF header and the UNIF file block tags, and if a match is found to the Database, it will strip out all the UNIF metadata and add a NES 2.0 header. UNIF-formatted ROMs can have file block tags inserted into the ROMs outside of the UNIF header. The Script will try to convert UNIF-format ROMs into NES format ROMs. The way the Script handles UNIF also deserves a mention. This can help you find bad ROMs or ROMs the Database does not (yet) recognize. will move all ROMs which the database does not recognize into an "unsupported" folder. This will not add any NES 2.0 features, which almost defeats the purpose of the header fixing tool because some games will not work correctly or at all without NES 2.0 features. There is an option to just modify the headers to use iNES 1.0 header features, "NES_20 = ". It is not quite as fully featured as an auditor program because it cannot easily tell you which ROMs are missing from the database on your system. The command becomes something like \python nes_fix_headers.py > changes.txt This will tell you the ROMs it recognized and changed and the ROMs it did not recognize. This XML file uses an entry for each game and markup language that looks something like this : As of 04-21-2020, the NES 2.0 XML Database contains over 4000 entries and may continue to grow. The Database almost completely covers the No-Intro NES set (3,012 entries as of 04-05-2020) and a good deal of the last GoodNES set (22,096 entries as of v3.23b). A download of the most current version can be found at that link. The most accurate and complete database for NES ROMs is the NES 2.0 XML Database. I cannot expect someone wanting a full set of proper NES 2.0 ROMs to manually edit the headers of over 2,900 separate files! However, while I can make a spreadsheet for easy accessibility, spreadsheets are not the best way to organize data for use by other programs. In my last blog entry, I announced the creation of an evolving database of NES ROM headers, focused on cartridge accuracy.
