How do i expand a rom with nflate???

Hi community.

I'm trying at the moment to apply a translation patch for a nes rom, But some roms needs to be expanded if they're going to work with the patch provided.

When i launch nflate a command prompt shows with the text "Original rom to be expanded", So what to do then??.

If i just apply the Translation patch to the rom it only boots up in a black screen with nestopia, Do you need the original rom? or do you have to use a specific type?. I know i have to expand it from 128kb to 256kb, But how??

Thank's

Hey, I am having a similar issue. Only thing is that I am following the instructions that were attached with the file

The game is Takeshi no Chousenjou, and while I end up doing everything correctly. In the end, it tells me the it couldn't find my rom file (Despite the fact that i literally just placed it in there). 

Does anyone know why this is? And how to fix it?

Without any details or links to the patch I can only guess that you have the wrong version of the game the patch requires.

I am guessing you are talking about this patch: https://www.romhacking.net/translations/1682/

*********************
PATCHING INSTRUCTIONS
*********************
 The ROM will need to be expanded with a program such as nflate first.
 Expand the PRG-ROM.

 Either apply the IPS version of the patch to an original Japanese ROM,
 or use a program such as upset (from byuu.org) to apply the UPS version.

 And I suppose you know not to apply it to a pre-patched ROM.

 This translation was tested on the 1986 version of the ROM, but looking
 at the differences between the two, it should be compatible with the 1990
 ROM as well. (technically, the only visible difference seems to be the
 date on the title screen. The mapper code was also changed slightly.
 My guess is the 1986 version ran on a PCB with bus conflicts and the 1990
 version did not. The 1990 version also contains a small additional routine
 that doesn't appear to serve any useful function: it reads from some address
 like $4420 that is believed to be unmapped and then follows with a branch
 with a relative offset of 0 (which again appears to be a useless instruction).
