Thx for your answer it made some things clear. But it hasn't changed much of my problem I am still getting the Original Rom has wrong size when using dpspatcher.exe. Of course I have looked everywhere to make sure I was doing the right thing as the program is really easy to use. I've got a folder with the game in it (6rz-ffa2.nds 131mb, jus-eng-dev03_05_08 4.9mb, dpspatcher.exe of course and jus-patcher-U0_1)
When i open dpspatcher i load 6rx-ffa2.nds in the first spot as the original, in the second spot i load jus-eng-dev03_05_08 as the patch and in the last spot i save the modified version as 6rx-ffa2P.nds(seen in some places that you need to place a P at the end but I don't think this is related). when i click patch it tells me that the original rom has wrong size and it creates a 0kb 6rx-ffa2P.nds.
So what is the size of the original rom? I have downloaded it several times and each single time the rom has been 131mb. I don't know what I'm doing wrong but I have tried everything I could to get rid of that error but never found a rom with a size different to 131mb.
On a side note(related nonetheless). Are emulators running untrimmed roms? Are the downloaded roms untrimmed? and I have understood that an untrimmed rom should be bigger than a trimmed one since trimming is removing unnecessary portions.
Thx in advance I hope I have given enough details to help you comprehend my problem and if not I can provide screenshots to explain visually.
