uCON64 v2.1.0 WIP (2017/11/08) is released. uCON64 is a tool to backup all kinds of video games. It supports almost every available backup unit for cartridge-based consoles and performs many other tasks like ROM hacking. uCON64 is completely Open Source Software and has been ported to many platforms using code from various people.

uCON64 v2.1.0 changelog:
- added (SNES) preliminary support for native Super UFO Pro 8 SD file format. Use --ufosd to convert a file to Super UFO Pro 8 SD format. More information is required for a full implementation and any help will be appreciated (by dbjh; thanks to cage for his help)
- added (SNES) --ufosds convert *.srm (SRAM) file to Super UFO Pro 8 SD (by dbjh; thanks to cage for the SRAM files)
- updated (SNES) added crack for Diddy's Kong Quest & Dixie Kong's Double Trouble that makes those games run properly on the Super Flash. It has been added to snescopy.txt, not to the internal cracks, because it may interfere with the already present cracks of those games. Apply it with --pattern (by dbjh, based on post by Tomy of ToToTEK on ToToTEK's Help & Support Forum)
- updated (all) fixed --xreset to really remove power from all programmable pins (by dbjh)
- added (all) support for EPP when using a PCIe parallel port card that has its ECP Extended Control register at a non-standard offset, i.e., most PCIe parallel port cards. Specify the offset in the configuration file by changing the line that starts with ecr_offset=. See the FAQ (question 53 and 54) for a more elaborate explanation (by dbjh)
- updated (all) fixed several mistakes in how different pieces of code tried to enable EPP or simply relied on a BIOS to have configured it right. As a result the meaning of the switches --xfalm, --xgbxm and --xplm has been reversed (the associated options use EPP mode by default and use SPP as fallback). Another consequence is that UserPort can no longer be used as I/O driver (by dbjh)
- updated (SNES) improved --id to the point where its help text can be shown (by dbjh)
- updated (SNES & Genesis) fixed several edge cases in MGD splitting code (by dbjh)
- updated (SNES) fixed crash when splitting files in Game Doctor SF3 format >= 100 Mbit (by dbjh)
- updated (all) made --pattern more verbose when -v is specified (by dbjh)
- updated (GBA) made --crp more verbose when -v is specified (by dbjh)
- updated (SNES) made -k, -f & -l more verbose when -v is specified (by dbjh)
- updated (Genesis & PCE) made -f more verbose when -v is specified (by dbjh)
- updated (all) fixed bug in code of --pattern that caused changes to be omitted in the output file (by dbjh)
- added (SNES & Genesis) --smgh split ROM for MGH. Its main purpose is splitting SNES HiROM games in MGH format. Splitting is required to make them run with an MGH (by dbjh, thanks to Mystic_Merlin for information and testing)
- added (SNES & Genesis) --mgh convert to Magic Game Hunter/MGH format. For SNES this does the same as --gd3, except that the resulting file will have an MGH name and no header. For Genesis this does something very similar to --mgd, but the resulting file will have an MGH name. For both consoles an MGH name file will be produced (by dbjh, thanks to Mystic_Merlin for information and testing)
- updated (NES, SNES, Genesis & NeoGeo Pocket) fixed --ns (by dbjh)
- updated (SNES) fixed bug in checksum calculation code if the cartridge size byte of the internal header is 0 (by dbjh, thanks to Mystic_Merlin for providing the PD ROM that triggered the bug)
- updated (SNES) added support for a few more cartridge configurations to --ufosd. Still more information is needed, specifically about the header of 8 Mbit HiROMs (by dbjh, thanks to Mystic_Merlin for sending the output of --dbuh for dumps made with his UFO SD)
- updated (SNES) --ufosd fixes the checksum and pads the output to a valid size for the UFO SD (by dbjh, thanks to Mystic_Merlin for information and testing)
- added (N64) support for Nintendo 64 DAT files containing CRC32 values of ROMs in Mr. Backup Z64 format, like what DAT-o-MATIC produces. It can be turned on by setting the property variable n64_dat_v64 to 0. See the FAQ question 57 (by dbjh)
- updated (all) fixed double suffix issue when using DAT-o-MATIC DAT files (by dbjh; thanks to eadmaster for reporting the issue)
