The 8kb .sav files bundled in the release NTRQ archive are a dump of the SRAM sector of memory in a NES game, which is also where the data of a NTRQ project resides; savestates are a dump of the whole memory- which includes the SRAM sector of it, and may be stored in a custom container file with an emulator or format-specific header; savestates aren't distributed in the NTRQ package.
puNES stores SRAM files in the next folder path:
(System drive letter):\(users folder)\(currently logged user)\My Documents\puNES\prb\
In my case, it is this folder path:
C:\users\sandbox\My Documents\puNES\prb
In Linux, using wine, that directory may be found at this folder path:
~/.wine/drive_c/users/(currently logged user)/My Documents/puNES/prb
with the filename of the ROM loaded, and a .pbp extension, rather than a .sav one; other than the distinct extension, they are same: One can copy the file named as ntrq-example.sav in the NTRQ archive, to the aforementioned prb folder, and rename it as any of the three, ntrq.prb, ntrq_NTSC.prb, or ntrq_PAL.prb, depending on which of the three ROMs in the NTRQ package, ntrq.nes, ntrq_NTSC.nes or ntrq_PAL.nes, you do intend to use, respectively.
Mesen works well for me in Mono, by opening it with the next command:
mono Mesen.exe
The mono program may be installed via a package manager on a Linux distribution on may use; instructions for, depends on the package manager a Linux distribution may be using: May you desire to install it, please query a web search engine for instructions on.
On Arch Linux, one may use the a package manager named as pacman to, with the next command:
sudo pacman -Sy mono
Does opening it using mono rather than wine, works in the environment you are using?
Upon the first time opening it, it will ask about whether to store data in the application folder, or the user folder, defaulting to the later option: Mesen saves SRAM files with the filename of a ROM loaded, and a .sav extension, in a folder named as Saves: If one chooses for Mesen to store data on the user folder, one can find the folder where Mesen stores SRAM files in the next folder path:
~/.config/mesen/Saves
To load the example provided in the NTRQ archive with NTRQ, on Mesen, one may copy the file ntrq-example.nes in the NTRQ archive to the aforementioned Saves folder, and rename it to one of three, ntrq.sav, ntrq_NTSC.sav, or ntrq_PAL.sav, depending on which of the three ROMs in the NTRQ archive you use, then open the ROM by selecting the file; Mesen looks for the content of a SRAM file matching the filename of the ROM, when loading one in this way: If one previously loaded a ROM, it may be displayed on the emulator portion of the screen, from where one may also load it; however, upon loading a ROM using this menu, it will automatically load a savestate that by default Mesen creates when leaving a ROM, without regard of a SRAM file.
The Linux version of Bizhawk does works for me, calling the script withing the archive, after untarring it, with the next command:
./EmuHawkMono.sh
It stores SRAM files in the folder NES/SaveRAM relative to the executable: Using either, ntrq.nes, or ntrq_NTSC.nes, will create a SRAM file in the aforementioned folder, with the next filename:
NTRQ - NES Music Tracker v1.8NTSC by Neil Baldwin (PD).SaveRAM
When closing either ROM or emulator; if one uses ntrq_PAL.nes, it will create a SRAM file in, with the next filename instead:
NTRQ - NES Music Tracker v1.8PAL by Neil Baldwin (PD).SaveRAM
One may try the example NTRQ project provided in the NTRQ archive, by moving the file ntrq-example.sav in, to the previously mentioned folder named as SaveRAM, and rename it to either this filename:
NTRQ - NES Music Tracker v1.8NTSC by Neil Baldwin (PD).SaveRAM
If one intends to load that example project in any of both the ntrq.nes ROM, or the ntrq_NTSC.nes ROM in: If one intends to load the example project in ntrq_PAL.nes, ntrq-example.sav must be renamed to have the next filename, instead:
NTRQ - NES Music Tracker v1.8PAL by Neil Baldwin (PD).SaveRAM
You are welcome to share here about how making a setup for using NTRQ goes for you, and also to ask about any regarding the process of, or otherwise, if anything, nitrofurano!
