HOLY SHIT YOU BEAUTIFUL BASTARD! lol thank you so much for doing this. I'm going to test some more files, but from what I'm seeing it works like a charm! I just told my brother that you did this and that it was like I was talking into a void for 10 years and then you came along. I feel like Tom Hank...

Holy shit! This is far more complicated than I had initially thought. Excellent work. If there is any way I can help you should you choose to continue, let me know. I've stepped back a bit from it since tracing assembly is way above my skillset, and haven't had the time to learn yet. Thanks for all ...

Not sure if any of this helps you, but I pasted the function's pseudocode into the Llama 2 chat bot and asked it to explain in general terms how the function was decompressing the data it was reading. This is what it spat out: The function you provided appears to be a custom implementation of a deco...

Holy crap, thanks for the response! Yeah, i know nothing about reading assembly haha. This sounds promising, I'm curious what you find! I'll try to take a look at sub_409E4A. I can't read assembly, but I can kind of piece together stuff form ida's pseudocode. Not sure how accurate that is though.

I've been playing around with swtiching out bits after the header information I know in the Mecc logo in the game credits. It's produced some weird results. It does look like the compression of the image is being broken up into 8x8 pixel chunks starting from the top left and going down a column, the...

I was reading up on old gifs, and they used to utilize the ability to have multiple images stored in the gif file and render them one on top of the other so you could use transparencies to build up a still image out of parts. This would coincide with the backgrounds in this game, since they containe...

Alright, call me crazy, but the fact that this compression seems to be lz77 related, and this game was cross platform mac/windwos3.1/windows95 at the time it was released, could it make sense that these were just gifs? Could this just be the compressed GIF data? I feel like the more I try to figure ...

I decided to send a CBMP file's image data to ChatGPT to see if it could figure out what type of compression method it was using. ChatGPT is convinced that it's LZ77 compression. I have zero experience with LZ77 compression, so I'm kind of stumped. I've been trying to watch some videos on it to see ...

Hey! Thanks for your reply. The size is indeed 8x8! Do you have any info on references or examples of this tiling method you could reccommend? Maybe if I can look at another example I can piece together how they were doing it. Randomly changing bytes has led to some weird stuff and a whole lot of cr...

So I opened up the 2 example files at diffnow.com to see if there were any similarities between them. It looks like there are, but I can't make any sense out of them yet.

What type of files are these supposed to be? Models/sounds/textures/etc...?

Do you have an example of a steam saved game from FIre Pro Wrestling you can post?

Hey guys, I've been working on extracting all of the game content from the main archive of a 1995 MECC game called "Opening Night." I've successfully been able to extract and rebuild all of the compressed RLE encoded bitmaps from the game. There are 2 types of bitmaps in the game however, ...

Hey! So, it's been a while, but I'm back to working on this lifelong puzzle haha. RLE files are completely done as of last time I was working on this. I was able to successfully dump all RLE files from the game into regular bitmap images. They were RLE compressed and used the color table I posted ea...

Disregard last 2 posts. My decompress function had an error.

It worked!

RLE files handled. Going to write up something that exports the bitmap files.
