MrVtR Posted October 31, 2023 Share Posted October 31, 2023 Hey guys, I'm trying to translate the "new" Metal Gear(MSX2 Version) for the Master Collection on Nintendo Switch Could anyone take a look at this file to try to find a way to extract and recompress the texts if possible? I got no luck digging the file bytes. At the moment, I can edit the text, but without increasing its size, there is probably a pointer/offset section within the file, but I can't find it. If you search by the string "infiltrate the" on the file, you'll be able to see the first cutscene strings on the game english.zip Link to comment Share on other sites More sharing options...
wssdude Posted October 31, 2023 Share Posted October 31, 2023 3 bytes seem to correspond to string size and then comes string, which is not null-terminated (you have to use the size from the 3 bytes prefixing it). This pattern can be verified quite easily if you start looking at the bytes in-between text. Unsure where the offsets might be also for now... Think if there are some, they are relative... Or on a second thought, maybe they are null-terminated and sizes are 2 bytes 🤔 Sizes are big endian in any case. Link to comment Share on other sites More sharing options...
wssdude Posted October 31, 2023 Share Posted October 31, 2023 More I look at It, more I get a feel this is a whole ROM somehow? Which is against rules... Feel a bit unsure about this file tbh... Link to comment Share on other sites More sharing options...

Feel a bit unsure about this file tbh... @wssdudethis isn't the whole ROM, there are a bunch of other files on the MSX game folder The uploaded file is on the Root path > fr > stage >mg1 > cache > ovr_nx > ovr_eu > english.raw If I'm not wrong, the "ovr" is from "Overlay", the ROM itself isn't on this file. The english.raw probably just have Overlay texts, since the font was redesigned to HD version Root path: "fr" folder Edited October 31, 2023 by MrVtR Link to comment Share on other sites More sharing options...

I found these string bytes too here, I tried to just change them to the new length, but didn't work. Also, the first 4 bytes of the file stands for the File Length, but no positive results from there too I think that in some section of this file, it have a offset sections, but I tried to search for the string position (little/big endian), and no matches too, so maybe relative?

wssdude Posted October 31, 2023 Share Posted October 31, 2023 Np then just seemed a bit suspicious cause there seem to be like textures or audio also in that file, looks like some bitmaps or PCM data how regular it is 😄 Couldn't the offsets be somewhere else? Is always a possibility I suppose 🤔 Wouldn't be first nor last format to have indices somewhere in one place and just blobs of data in other place.

wssdude Posted November 1, 2023 Share Posted November 1, 2023 Maybe it would help to have some other data for comparison 👍 Link to comment Share on other sites More sharing options...
