Homebrew Adapt NeoDS to GameBoy Macro

KyrosBR · Feb 24, 2020

Good Morning! I needed to create a forum account to be able to thank! I don't speak English very well, so know that my text comes from Google Translate.

I have been following NeoDS for many years and use it today! I was very happy to know that there are people (xonn) interested in improving it. I tested your update and I don't know what you did, but I saw a fantastic improvement in Samurai Shodown III (1 of the only 3 games I've tested so far). Unfortunately on the Nintendo DS Lite it only runs on the bottom screen of the games. Is it possible to leave the top screen being the default to play and the settings the bottom screen or to be able to change it?

And yes, when playing for the first time with the audio off, the top screen you can see the menu / settings screen. If you load a new ROM enabling the sound, this screen disappears.

Hello @KyrosBR.
I'm going to answer your message in a google translate fiendly mode

First, I have not modified a line related to emulator core, so this version should works like last official release (0.2.0)
Second, I did some changes to create a special version to use in a GBMacro (a NDS with only one screen), so the program shuts down upper screen in order to save energy, and all interactivity is located in bottom screen.

It must be my imagination then. Still, thank you for the answer! Do you intend to work on something else in the project?

Depending on the amount of free time. Anyway, I put code and libs necessaries on github, so everyone can continue with the development

I understand. I hope you can continue to progress.

It was very good! Tested and approved, thank you!

But didn't you use a libnds version that wasn't the one that was last compiled with? That could have something to do with it

Yes. At first, I tried to work with a bit modern libs, but a lot of problems appeared (sprite layers lost, touchscreen disabled...), so I started over from original source code with libraries from 2007, and everything was correctly compiled with zero errors/warnings. After that, I wrote my own lines of code to swap screens.

Hi Xonn, Does your version use memory expansion pack? If yes, can you please share which games it will improve and how? thanks

Sorry, I just modified some lines from 0.2.0 version in order to show games in lower screen. Other features have not been touched

I contacted the original creator of the NeoDS and he mentioned your code is using RAM extension and he posted your added lines (attached). There is some confusion

The GitHub messages? That was not with the creator. That was with NightYoshi370 (aka me) and you, not whoever originally made NeoDS

Anyway, I don't have much experience with devkitarm and libnds, those lines of code are unknown for me. When I modified source code, just put some lcdSwap() functions in some parts of the code, nothing else (I think).

So we can summarise the RAM extension is not used in both version then. thanks.

Bro i've seen your work on the 3DS forums, you think this can run on a 3DS somehow? I wouldn't mind using your version that neglects the upper screen as long as it runs. Sorry for the offtopicness.

Is there a video explaining how to do this (in Spanish, sorry). Check it here.
