so does the game create the save file when it first runs, or do they need to have an existing save file?

TWLoader will create the file if it doesn't exist, so the game can write to it.

ok thanks, so does anything need to be put in any files which determine the location, or is that automatically done as well?

Updated to unofficial bootstrap release, edited the lines in bootstrap.ini and tried to put the save data for the Ronic Rush from NO$GBA.
Raw sav-file from No$GBA seems to work just fine, as it seems.

Sadly it didn't work for me on MegamanZX

What's the SAV_PATH?

[NDS-BOOTSTRAP]
NDS_PATH = fat:/roms/nds/SM64DS.nds
BOOTSTRAP_PATH = fat:/_nds/bootstrap.nds
BOOST_CPU = 1
NTR_MODE_SWITCH = 0
DEBUG = -1
LOCK_ARM9_SCFG_EXT = 1
SAV_PATH = fat:/roms/nds/SM64DS.sav

Saving only works for early DS games.

Sonic Rush ROM can be patched with MaxOverload patcher v1 method. If I get it right that's what determines if the game can use save redirects as of current or not. Google for MaxOverload 1.2 and check if your ROM can be patched.

Question about the latest release:

This release bring better speed and save redirection support for retail roms. You can specify in nds-bootstrap.ini the option SAV_PATH to redirect to a save file dumped with TWLSaveTool. A new version of TWLoader is in preparation to take advantage of that.

To the ones that have tested unofficial builds : there have been a bug at some point that may have corrupted your rom files, please check and just replace you corrupted rom files by the originals ones.

A fair warning and note to all: If you don't wish to save, keep ALL cards out of SLOT-1. THE SAVES WILL BE OVERWRITTEN IF THE SAVE CHIP MATCHES and the save redirection patch fail.
However, if you wish to save like this, TWLSaveTool can tell you the chip type. Just backup the old save first.

If this release brings save redirection, why the warning about keeping cards out of slot 1? Or is this simply a "just in case" warning?

It still says that redirect may fail. And it also doesn't work for all games, just for some of them.

I think lego star wars: the complete saga isn't actually freezing like I said it was before, but the intro is super slow. It went like 15 frames in 30 minutes about, so less than 1 fps for the intro video.
UPDATE: 1 hour later, and still progressing. i think this is about 2 fpm (yes, frames per MINUTE). may leave it on overnight see how that goes.

Does the save read/write works in Lunar Knights? This a game that currently should requires arm7 patching for save ("Max Crass Method" https://gbatemp.net/threads/how-to-patch-games-with-an-arm7-bin-file.94755/ ).

Yes, but it'll require hacking TWL_FIRM.
