Tutorial Play/port your GameMaker games on NintendoSwitch

[lordelan]

To get them to work you need the am2r game maker studio 2 source code and I only have them partly working. It's a temp save in the /rooms/int folder that i made in the romfs files before recompiling it into am2r.nsp it's not a good way to do it because it triples the file size of it but 350mb is still not bad.

So you got saves working (with your "workaround") with the only downside, that the game is bigger?

No it's only a temp save it will delete the save if you restart the game

That's a shame. Seeing it on the Switch just like in your video felt right.

Is there any chance of a video tutorial getting released for this?

I would but if you don't have the source code for it to work then you can't get it to work.

I would love to see Zelda makers and Mega Man makers for it. Mockup games, I mean.

I have been looking to see if you can also make Flash games port. BrawlHalla is a Flash game, it could be used for that purpose.

Play Rayman Redemption game would be wonderful, sadly it use a huge external file for the audio :
"audiogroup1.dat" 1 Gb

I have a data.win file with bytecode version 17, but the Undertale NSP uses bytecode version 16. Is there a nsp that has bytecode version 17 I can use as a base? What about Deltarune or the update nsp for either?

Edit: Deltarune is bytecode version 17. The update nsps are just a bunch of fragments and I don't know how to modify or merge the data into the base nsp.
Edit2: No luck, it still crashes. I think the version of GM:S used (2.3) is just too new.

I'm running into this same issue now actually. I think the GM:S version is the issue, as I was able to get a game compiled on GM:S 2 from earlier this year to run, but not one compiled very recently.

Does anyone know of any way to change the Title ID or any other GMS games on Switch other than Undertale and Deltarune? Trying to install 3 GMS titles through the basic method and have only been able to get Undertale and Deltarune replaced.

To change the titleid you need to extract and rebuild the nsp. I don't know if NSCB has a function for this or if there are any other tools to automate it, but the manual way would be to extract with hactool, change the titleid wherever it occurs, and rebuild with hacPack or similar.

I've tried to do this, but didn't really have much luck, with the NSP returning as a ~500KB file. I've basically given up at this point, might consider trying again in the future but as of now I don't really mind.
