Using ( FileStream dict = new FileStream( '.dictionary / old file path ', FileMode. Using ( FileStream output = new FileStream( '.some output path ', FileMode. This is just how the algorithm works for VCDiff. The file must be fully read in first in order to encode properly. The dictionary must be a file or data that is already in memory. Vector intrinsics and the Span and Memory memory APIs require. Should be able to support up to 2-4GB depending on your system. I tried to test as thoroughly as possible between this and Google's github version. It is fully compatible with Google's open-vcdiff for encoding and decoding.

Will be added later if requested, or feel free to add it in and send a pull request. The only thing it does not support is encoding with a custom CodeTable currently. This includes proper SDHC support with interleaving and checksums. This is written entirely in C# - no external C++ libraries required.

This is a full implementation of open-vcdiff in C# based on Google's open-vcdiff. The original readme, with some changes to the API usage examples A lot of work has gone into optimizing out the overhead of garbage collection and memory access through Memory, as well as parallelizing computational work with SIMD extensions. Speeds are comparable, albeit slightly slower than the native xdelta3, depending on the chosen blocksize. Wherever possible, SSE3 or AVX2 extensions are used on supported systems. Xdelta3 with Adler32 Checksum and VCD_APPHEADER (without compression) Xdelta3 with Adler32 Checksum (without compression) SDHC Interleaved (with and without Adler32 Checksum)

Only patch files without external compression ( -S none) are supported. Testing was done with xdelta 3.1, support for xdelta 3.0 patch files has not been tested. Support for xdelta3 checksums have also been included. Non-scientific preliminary testing shows up to a 30x to 50x speedup compared to the original library when diffing a 2MB file. Large chunks have been rewritten, and heavily optimized to be extremely fast, using vector intrinsics, as well as Memory and Span APIs as well as a sprinkling of unsafe pointer access to eke out every bit of performance possible. I use the mobile firefox app on my chromebook, and when i click browse on the rom or patch things, it filters out all files, even z64 and bps files arent there. Patch creation (maybe) If you happen to encounter any bugs please report them here. I die a lot in this hack, but its always fun making new progress.This is a hard fork of VCDiff, originally written by Metric, written primarily for use in Snowflake. VCDiff (xdelta) Todo: VCDiff secondary compression support. With the life capacity upgrades, it makes up for the tougher challenge. It's definitely NES hard, but not so much that I can't progress. But something told me to play it anyways and check it out, and wow people saying it was easy were totally wrong. When I first heard of the hack and heard that it considered easy because of the lack of random encounters, I lost interest right away.

I'm having a good time with that hack, about to get to the 6th dungeon now. Said list also has a tab with non improvement hacks, like the ones you listed here.ĮDIT: Oh crap I just noticed your username, you're the author of Amida's Curse! Dude you are a genius, I love your work on that hack! Really well earned respect from me. If you're interested I could post the link here. I actually maintain a list of improvement rom hacks, that aims to select the best possible improvement hacks per game. I'm glad we live in a day where there's fair zelda 1 and zelda 2 hacks, that being the ones you listed here. Hacks should aim to be fun, not frustrating and unbeatable. I like fair challenges that feel like regular games, not everyone is an expert or a masochist. I can't stand rom hacks that focus on making the game super difficult. I plan on playing Zelda Perils of Darkness next, I had my eye on it before this list was posted. I haven't played them yet so I will be getting to them soon. Best Zelda II hack for sure! It deserves the praise it gets.Īll the other hacks you listed have always been the top rated hacks that I heard about and I'm glad they're still recommended. The world is really well done and it feels like im playing Zelda II for the first time all over again. I started playing Zelda II Amida's Curse recently and I love it so far! It's tough but also well balanced. Coincidentally I started getting into rom hacks lately and sorting out my collection with new popular hacks, so this is really awesome timing!
