    Homebrew [Release] Vice3DS (C64 Emulator)

    Using GPU_NEAREST will bring other problems: you can see it clearly with a resized image with vertical lines, because the resize is performed by scanlines and different lines use different offsets, so vertical lines come out a little "jagged". Several people complained about this in my port of...

    Homebrew [Release] SDL-3DS 1.2.15 - Simple DirectMedia Layer for 3DS

    You should use the SDL version in devkitARM. The code is the same (don't think someone updated it) but all the dependancies to build it are updated. EDIT: I see that devkitPRO site is down.

    Homebrew [Release] SDL-3DS 1.2.15 - Simple DirectMedia Layer for 3DS

    There is already. But with different approach and no more maintaied. To be honest my version too is no more maintained, but at least it's (should be) compatible with latest devkitARM changes. About coding for the DS, I don't know very well the DS toolchain, and at the moment I'm more...

    Homebrew [Release] SDL-3DS 1.2.15 - Simple DirectMedia Layer for 3DS

    You can make a copy of the surface structure and make the data field to point at the first byte of the second half of the surface bits buffer. Should work.

    Homebrew [Release] SDL-3DS 1.2.15 - Simple DirectMedia Layer for 3DS

    You should look at second post of this thread: you can also look at some of my ports on github for reference. Using SDL_SetVideoMode(SDL_DUALSCR) you can make a surface of 320x480, so the upper 320x240 will be used for top scren (with black lateral bands) and the lower 320x240 will fil the...

    Homebrew [Release] SDL-3DS 1.2.15 - Simple DirectMedia Layer for 3DS

    You have to customize the SDL code to handle the C-pad. If you try you should find that it's very easy.

    Homebrew [Release] Handy 3DS - Atari Lynx Emulator

    When you say "recognize" do you mean the files arenot shown in the fil list, or that they don't work? I have about 90 games in the ROM folder + others in a HOMEBREW subfolder. About DS power: - with the New 3DS my emulator runs fullspeed, with an Old 3ds it runs acceptably with frameskip 2...

    Homebrew [Release] Handy 3DS - Atari Lynx Emulator

    The Nutmeg port on 3ds is already done, will be released after the game is completed. For Switch, probably I'll port all the retroguru games next summer. I'm not going to make other works on th 3ds in the short term, but maybe in the future I could.

    Homebrew [Release] Handy 3DS - Atari Lynx Emulator

    For Retroguru I'm finalizing the release of Super Nutmeg (demoversion released for Dreamcast at Retrokomp 2018, but in the final release there will be a lot more things) and testing my port of Xump to the Atari Lynx with the support of the developers at Atariage. And, when I have more time...

    Homebrew [Release] Handy 3DS - Atari Lynx Emulator

    An basic answer could be: no! But the questions is not clear. They have two different architectures. How would you compare the power of the two systems?

    Homebrew [Release] Handy 3DS - Atari Lynx Emulator

    You should ask in the DS forum for this. But I think it's not possible to emulate Atari Lynx with the DS hardware. It doesn't matter if you run a DS program on the 3DS, it won't use the full power of the 3ds.

    Homebrew [Release] Handy 3DS - Atari Lynx Emulator

    @rushfan2112 is probably running emulators for the DS system on the 3ds, and I don't think the DS has enough power to run a Lynx emulator (DS code on the 3ds don't use the full 3ds power). The CIA version of the this emulator is not stabe, mostly because it was one of first work of mine and...

    Homebrew Homebrew Development

    From the above quoted line you can see the real problem is that the compiler doesn't recognize mkdir as a function, ad it's suggesting to use rmdir because it has only one different char (such hints are useful for finding typos, but don't rely too much on them in other cases). To make it...

    DC Dreamcast Homebrew Game: Super Nutmeg (Playable DEMO) by Retroguru

    We had the original sources from Photon Storm guys with the permission to use their material, but after a fast look at it I decided to remake it using the Retroguru engine (more C a framework based on SDL than a real game engine) starting from the code of Hermes. It was very usefull to make a...
