nds-bootstrap loader: Run commercial NDS backups from an SD Card

Jubash · Jan 15, 2017

Just giving some feedback:
In Yoshi's Island DS, the game would freeze in a black screen after the initial cutscene, before the title screen, in the previous official bootstrap release.
In the current one, I can get past the Title screen and save selection, and right after that it starts another cutscene. In what I would assume to be the end of this second cutscene (after selecting my save file), the game returns with an error regarding the Save Data. It informs me that was unable to write to the save file and to remove/reinsert the game card.

So do you need to change the SAV_PATH in the nds-bootstrap.ini file everytime you want to save with a different game or can you add multiple SAV_PATHs?

Have you patched your ROM with maxoverload patcher v1 method? As of current the games that capable of such patching require it for save redirection compatibility. This may solve your issue. Requirement for patching also mentioned in compatibility list already.

Latest TWLoader should handle it for you, I believe. Haven't tested it personally since I have only 1 game that can save, but it always edits corresponding PATH-lines to latest ROM you've been running.

Yoshi's island ds requires arm7 swapping (so called "Max Crass Method") to works for now. I have tested it personally and I confirm it works this way.
Follow the indication in these 2 very old threads and it should work, you just need to change binary file via dslazy :
https://gbatemp.net/threads/how-to-patch-games-with-an-arm7-bin-file.94755/
https://gbatemp.net/threads/the-incredible-hulk-working.90078/

I will add an option in bootstrap to swap the binary easily (something like a DONOR_PATH option in the ini file so you can select another rom to use the arm7.bin from it) but for now you have to do it the old way.

Here is the titles that are working with this method :
- Tetris : fully playable once patched
- Yoshi's Island DS : playable but loading time are very slow
- Contact : playable but loading time are very slow

Title that may works with this method (I have not tested yet) :
- Point Blank DS
- Lunar Knights

The max crass method not working for Rosario vampire eng patched. Anything else I can try?

frobinson54 · Jan 15, 2017

I just updated to the latest version of TWloader (both cias updated), and it is stuck on the "Checking TWLoader Version" message. I see in the changelog that this is fixed, but it isn't working for me. Should I just clear out my TWLoader Folders (except roms), and reinstall the entire thing?

Edit- oops. Sorry. Wrong thread.

SM64ds works well in multiplayer?
Can you load and save to cartridge (instead of sd)?

pokemon mystery dungeon explorers of sky works but its kinda laggy

Lego Star Wars: The Complete Saga loads, but the intro plays at a speed of less than 1 frame per minute, so it takes 8 hours just to get to the main menu. Then you have to hold down A for another hour to select "new game", and after that, it gives you a black screen saying "the DS card has been removed". Anyone know what this means? (other than I have too much free time)

After patching Tetris Ds and Yoshi island Ds with the max crass method, twloader crashes when I attempt to go to the page that they are on. Is there a fix for this?

This is cool...would it be possible eventually for auto detection?

How did you make it work? Mine still throws me a save read error

Edit: Blue Rescue Team works after patching it with MCM.
(Tho expect huge loading times, specially during the introduction, partner selection screen, etc)

Edit 2: Explorers of Sky gave me save read error in both regions, even after applying the MCM patch.

I did the max crass method on Tetris DS, but the game still gives an "unable to read the data" error. What am I doing wrong?

Acelib · Jan 15, 2017

Sorry if this is a newb question but is there any way to make games with a white screen upon boot work?

If the game in question is not listed as compatable - probably no. At least not until performance of bootstrap will be improved. Don't forget - it's still in development.

TLNiles · Jan 16, 2017

@ahezard small question. It seems that the last unofficial bootstrap right before 0.2.0 (when save reading was implemented) been behaving better with Sonic Rush than current official and unofficial ones. I can clearly remember beating down Night Carnival boss without any fps problems, but with current official and unofficial releases I'm having serious framerate issues on that boss. Is there any hope that this specific bootstrap release is still saved somewhere so I'd test it more carefully and see that I didn't actually dreamed it all?
(I might have beaten that boss on No$GBA to make myself a save data though, but I can't remember clearly as of current, so I'd really like to test it out if possible)

According to the list, Ace Attorney Investigations Miles Edgeworth works but the first cutscene in episode 1 takes a while to load. Does this game support saves?
And when I launched Beta 1 of ErmiiKart (hack of MKDS) using a patched Mario Kart Ds (Jap) rom for the hack to work, I was given this screen when it attempted to load.

This also happened regardless whether I had
Save data or not.

ElyosOfTheAbyss · Jan 16, 2017

when I compile it, should I use nds-bootsrap.nds or bootstrap.nds?
