Egh, I don't like having to be the one asking for things, I just like recycling old help that other people got but... I can't remember where I saw the solution for this problem.
I've found myself in a bit of a bind. I'm just trying to decompress the gamedata.bin.lz that comes with the hack, so I can [insert hackerman things here], but batchlz77 keeps reporting the file isn't compressed when I do the whole dance of deleting the first four bytes and all that jazz. If I refrain from deleting any bytes before decompressing, not only does it actually allow me to decompress the file but, weirdly enough, it works with nightmare anyways. So life goes on and I make my changes, then come time to actually boot the damn thing in hans, I get a black screen. BUT, I only get this black screen after hans is done doing its thing but before the game actually boots (I manage to make it passed the white bar issue that hans sometimes gives). I'll try to hash together a text-based diagram, depicting my steps.
1. Unzip the hack > 2. Delete the first four bytes of the gamedata.bin.lz > 3. Attempt to decompress with batchlz > 4. Fail consistently as Batchlz reports the gamedata.bin.lz is not a compressed file (it only does this if I do any byte deleting)
The above is what happens when I attempt to do it the way I learned to do it the first time, which involves deleting bytes before editing, then replacing afterwards, finally when finished you proceed with the normal process of making a hack for Hans. Below depicts the process I've been trying to do because, unlike the above process, the below process almost works, I don't get stuck on the decompression step.
1. Unzip the hack > 2. Decompress with either batchlz or FEAT without any byte deleting > 3. Make edits to things with nightmare > 4. Save > 5. Recompress the gamedata.bin.lz > 6. Change the first byte to 13 and add 1 to the second byte > 7. Repack everything then Rebuild the romfs > 8. Save as 00179600.bin (NA Conquest cart) > 9. Delete everything down to line 1000 without actually deleting line 1000 > 10. Save as 00179600.romfs
It's been a long time since I've last been here (last current version I monkey'd around with was released in December if that gives any indication) and, apparently, much has changed with this hack lmao. I've been trying to do everything based on my memory but without luck or success. If someone can direct me to a thread where this is resolved, or give me a hand with what I'm doing wrong then that would be the greatest.
Very sorry for the gigantic wall of text, and another sorry if my process is hard to follow, I was trying to be as descriptive as possible but I feel like I achieved the opposite.
