Homebrew [W.i.P.] RPG Maker 3DS

[exelix11]

how do I load a created game onto my 3ds??

You can't use directly a game made in rpg maker, you must recreate the game from scratch in the game builder, which I'm working on, now I must fix some bugs and then I can publish a compiled version,for now it's a map editor,you still need to know lua to edit other parts of the games

easy Can't wait for it.

 

[Sr. G]

does anyone know if rpg maker vx is compatable with this loader???

no, this is not a port, this can't run games or porject from RPGMaker PC.

how do I load a created game onto my 3ds??

this is not ready yet, apart, this can't load a created game from others programs, only load games from RPGMaker3DS

 

[DarkRioru]

where do I download rpgmaker3ds? and is it free??? the default price for rpgmaker vx ace is like $70 and I downloaded the lite version

You are reading the forum page of the project.
It is a Work In Progress.
In the first post of this thread you can find a github Repository including the current state of the source code for the 3DS side of the application (the engine).
It is not complete yet.
There is a PC side of the application (used to develop the games), far from complete also. Maybe you can find a link to the code or ask the developer here, I think that one is developed by @exelix11.
It is free.

Would it be possible to create a program that ports from RPGMaker PC to RPGMaker 3ds. Instead of trying to make them work natively?

Probably not, or at least not without doing a lot of junk to get it to work well. It'd be kinda fun to play Megaman Sprite Game on the go, though.

You can watch EasyRPG porting for this, it will support RPG Maker 2k and 2k3 projects if i'm not wrong ( http://gbatemp.net/threads/rpg-maker-emulator-player-possible.395253/#post-5635789 )

I uploaded on GitHub the new syntax for map files (Letting @exelix11 to work on new export system for the Game Builder).
This system is currently quite bugged on rendering so if you try it and notice something strange, it's normal.

Well, too bugged, i downloaded the 3dsx and the folders from github, when i select new game after a few seconds the app crashes saying:

Error:[string"?"]:42:attempt to perform arithmetic on a nil value (global "map_lenght")
Press A to restart etc.. etc..

i'm using ironhax on 9.9 may be this the problem ?

Thanks, now it works

Solved all the rendering issues and also added some level3 elements to the test map to test alpha blending and framerate.
With the new map rendering system, RPG Maker is stable to over 30 FPS and it allows to load also big maps (Like WorldMaps and similar) without any framedrop. ^^

Updated GitHub repository with these changes.

So, I know this isn't done yet, but when this IS done, if someone were to attempt to create sorta like a port of an older RPG game such as Chrono Trigger or Dragon Quest or EarthBound, would it be better to use RPG Maker 3DS or just to re-build the whole thing from the ground up?

RPG Maker 3DS will give you an environment to easily create 2D RPG games for 3DS like RPG Maker 2k/2k3/XP/VX does for PC, so you'll probably find way more better to work with it instead of creating the game engine from scratch.

This is exciting! Will the bottom screen support touch controls and allow the creation of menus and such?

Touch controls probably will be added for 3DS only (cause my final goal is too create a multiplatform RPG Maker which can run on whatever console can run lpp).

Will test the newest version when I'm home! Thank you Rinnegatamante !

In next days i'll try also some cool stuffs like stereoscopic 3D support for layers in map scene. I have to see if framerate is good enough to add this feature (i think it could be a cool feature).

Have tried it a few days ago. It worked pretty wel with stereoscopic 3d, but I have to check if I'm able to find the Sourcecode again (did it on a virtual machine at work)
