Dreamcast-Talk.com

Hi all,

I decided a separate thread was needed for this update, as this application has changed so much from the time where I first announced it here. This morning, I released v1.3 of "Universal Dreamcast Patcher" with two VERY AWESOME new features:

1. A separate utility for automatically building a patch based on changes between original retail GDI and a modified one.
2. Usage of xdeltas to not only bring a massive reduction to patch file size, but also to ensure no whole files containing copyrighted content are distributed in a patch. Instead, just the delta/diff of said files are distributed (as it should have been all along!).

You can download these utilities and read more about them on my GitHub project page:

PS: A special thanks to VincentNL for finally giving me the nudge I needed in order to implement the very, very important xdelta feature.

I realize I've never posted updates to this thread after v1.3, so let me do that, as I just released v1.7 this morning

Here are all the changes since v1.3...

Version 1.7 (2024-11-08)
• For both the patcher and patch builder, added support for GDI source disc images that use 2048-byte-per-sector ISO data tracks instead of standard 2352-byte-per-sector BIN data tracks.

Version 1.6 (2023-07-17)
• Fixed bug in processing Redump-style CUE disc images with more than 10 tracks (Issue #2).
• Enhanced integrity checking of patched GDI output.

Version 1.5 (2023-05-13)
• Eliminated IP.BIN-patching helper tools in patch-building utility, with code now directly implemented in the application itself.
• Changed some labels in patch-building utility for clarity ("Unpatched GDI" is now "Original GDI" and "Patched GDI" is now "Modified GDI").

Version 1.4 (2022-11-24)
• If patch utilizes xdelta, the current filename being patched is now displayed in the progress status message, avoiding the appearance of failure when processing large quantity of files.

Haha, and now a fix to a bug that existed since the beginning and I never knew it!

Version 1.8 (2024-11-08)
• Fixed bug in both patcher and patch builder when processing GDIs with over 90 CDDA tracks.
