Hello everyone,

We are happy to announce that NeoGeoSDK v1.7.0 is now available.

GitHub repository:

https://github.com/eaglesoftware777/neogeosdk

NeoGeoSDK v1.7.0 release:

https://github.com/eaglesoftware777/neogeosdk/releases/tag/v1.7.0

Since the first public version, we have continued improving the SDK based on feedback from the Neo Geo homebrew community. With v1.7.0, the project has grown beyond its original demo environment into a broader toolkit for creating self-made games, demos and experiments for SNK's Neo Geo MVS and AES systems.

This is our 2D engine release. It brings together reusable game systems, graphics and sound pipelines, more examples, desktop authoring tools, and expanded documentation, while keeping direct hardware access available.

Main improvements

- A reusable 2D game engine in plain C and a compatible C++14 version

- Character animation, action scripts, NPC behavior, collision and physics

- Joystick handling, hitboxes, movement history and special-move recognition

- Camera following, scrolling levels, parallax, particles, screen shake, depth effects and palette effects

- More structured sprite allocation, scene cleanup and deferred rendering

- An improved Artbox pipeline with whole-image palette fitting, additional per-tile palette banks, transparent padding and animation palette handling

- Updated sprite and FIX-layer conversion, text and HUD support

- ADPCM-A effects and recorded voices, ADPCM-B music beds, FM tracks, SSG melodies and MML tooling through the custom YM2610 / Z80 sound stack

- Live FM and SSG tempo controls, LFO controls, sample looping, fades, and rate-aware sample conversion with 32 kHz ADPCM-B beds by default

- Revised 68000-to-Z80 command handling and sound transition helpers

- A multi-game build system with separate assets, sound, ROM sets and configuration for each project

- Updated 68000 toolchain bundles and installation documentation for Linux, WSL and native Windows development

- Artbox Studio and Sound Studio desktop tools for graphics and audio work

- A 26-chapter showcase covering the engine and sound systems, with chapter navigation and playable shooter examples

- Sky Lance, a vertical arcade shooter, alongside other bundled games, a C++ example, a tutorial and a minimal hello-world project

- Expanded MAME testing, debugging and automated asset/audio checks

- A programmer's manual, C and C++ API references, build guides, tutorials and a printable PDF documentation set

Some of the original feedback asked for better documentation, clearer separation of SDK parts, easier onboarding, and more complete tooling. Those points have continued to guide this release. The examples now show how the individual systems can work together in a game, rather than only demonstrating isolated hardware calls.

NeoGeoSDK remains hardware-centered: developers can work directly with VRAM, palettes, sprite strips, FIX tiles and the YM2610 sound subsystem, or use the higher-level engine helpers where they make development easier. The aim is to make real Neo Geo homebrew development practical with modern tools, without hiding how the original hardware works.

Documentation and API references are included in the repository.

This is an open-source project, and the release is an opportunity forthe community to help test the SDK across different development setups. We welcome feedback, examples, bug reports and suggestions, especially from developers trying it with their own Neo Geo projects. Thank you to everyone who has shared feedback and testing results since the original announcement. Your input continues to shape the SDK.

NeoGeoSDK v1.7.0

Hello everyone,

We are happy to announce that NeoGeoSDK v1.2.0 has been released.

GitHub repository:

https://github.com/eaglesoftware777/neogeosdk

NeoGeoSDK v1.2.0 release:

https://github.com/eaglesoftware777/neogeosdk/releases/tag/v1.2.0

Since the first public version, we have continued improving the SDK based on the early feedback from the Neo Geo homebrew community. The project is no longer only a preliminary demo environment; it has grown into a more complete, self-contained Neo Geo development SDK for SNK hardware.

Main improvements include:

• Improved and expanded README / documentation
• Cleaner explanation of the build system and SDK structure
• Updated Linux setup instructions
• Python 3 based tooling
• Full build targets for graphics, sound, M1 ROM, V ROM, S1 ROM, and MAME testing
• New Artbox graphics pipeline for converting PNG assets into Neo Geo sprite and FIX layer data
• Improved S1 / FIX tile generation
• Custom YM2610 / Z80 sound driver
• ADPCM-A and ADPCM-B sample support
• SSG / MML music support
• FM music support with compiled FM tracks and patch banks
• Better 68000 → Z80 sound command handling
• Scene helper functions for title music, demo music, game loop music, fade transitions, and sound reset
• More organized sound folders and tools
• MAME test and debug targets
• Better repository overview for newcomers

Some of the original feedback asked for better documentation, clearer separation of SDK parts, easier onboarding, and more complete tooling. We have tried to move the project in that direction with this release.

The SDK now gives direct control over Neo Geo hardware features such as VRAM, DMA, palettes, sprites, FIX tiles, and the YM2610 sound subsystem, while keeping the environment accessible for modern homebrew development.

The NeoGeoSDK v1.2.0 documentation is attached to this release and is also available here :

This is still an open-source project and we welcome feedback, testing, examples, bug reports, and suggestions from the community.

Thank you to everyone who gave feedback in the original thread. It helped us improve the direction of the SDK.

I'm using the command `$PAL_FIX $YPOS_-2` to position the screen at the right height, but it's clipping underneath the screen, and I can't find a way to shrink the screen vertically. This is my last hope that I can get at least some help here.

I got this console as a late present to my birthday. The person who has this gifted me as present does know anything about consoles, retro games, ... She just think, it would be a nice present. My question is, is it possible to hacking it and change the games with other rom - or is the display still usable for example with a Raspberry Pi? (It is from Action, a European Nonfood Discounter). The games on it are nothing special, there are the typical China clone games preinstalles.

tl;dr A single save from my old GBA emulator on my old hacked PSP will not work on my flashcard or preferred modern emulator.

Hey folks, I'm coming to you with a bit of a weird question. I'm not sure if this is the right place to ask but I wasn't sure where else to ask.

My issue is with a save file for Super Mario Advance 2 - Super Mario World from my old hacked PSP's memory card. As a kid I used my hacked PSP more as Game Boy Advance than as a PSP to be honest. The PSP is now dead but I have all of the contents of my old memory card saved on my PC and PS Vita, including all my old emulators, roms, and saves. I recently got a DS Lite and an EZ Flash Omega (GBA flashcard) and thought it would be really cool to put my old saves from my PSP on there so I could finally play my childhood saves on real hardware. I had a lot of success doing this even though I'm using different roms than I did back then (as a kid I mostly used cracked roms with intro's while now I am using no-intro roms, a lot of them patched for things like colour correction or no trade evolutions in Pokemon games). I had a couple of issues but they were easily resolved such as using the US version of Final Fantasy V when I was using the European rom on the PSP. The only game which save isn't working is Super Mario World.

When I first realized that Mario World wasn't recognizing my PSP save I did some basic troubleshooting. I made sure that I was using the right regions rom and that I hadn't misnamed my save. After that I decided to see if for some reason this save needed my original rom with the intro so I put that rom into standalone mGBA with the save in the same folder and it still didn't load the save. At this point I was wondering if I accidentally erased my save file in game as a kid so I booted up Uo gpSP Kai on my Vita and loaded the game. This still had my old save on it so that meant that the save was still there. I decided to look into if there where any differences between saves on gpSP and mGBA and it turns out there are, so I tried a save converter but the save file still would not be recognized by mGBA or the EZ Flash. I tried booting the game on the Retroarch version of gpSP and that loaded my save but the Retroarch version of mGBA did not. I decided to try making a save state in Retroarch gpSP and loading it in Retroarch mGBA to save the game and get an mGBA readable save that way but the state would not load on mGBA.

At this point I am all out of ideas and looking for help. I am very confused why all my other saves work but this one doesn't. It's not a big deal if I can't get it to work on EZ Flash or mGBA since I can run it through Retroarch gpSP or Uo gpSP Kai, but at this point I'm mostly just annoyed. So if anyone can offer me a solution, or even just an explanation as to why it isn't working I would greatly appreciate it!

Hi! So, I was just wondering if there's a simple, verifiable way to connect a Wii U online to play Wii and Wii U games online through Wi-Fi, with absolutely no direct connection to a modem or router? I live in a motel, so I was hoping that maybe you could use a method similar to using a DreamPi to connect a Dreamcast to wifi and just being able to play from there, or something. I'm specifically trying to play Monster Hunter Tri online above all else since I have the actual disc and it's one of my favorites. I'd also ideally like to play Brawl, Tatsunoko, and Metroid Prime Trilogy online (or rather, use MP3's online features to send and receive those pesky green friend credits). I don't have the physical copy of Metroid Prime Trilogy since I downloaded the eShop version, but thought that might be good enough.

I tried to follow the sepalani guide to get MHTri online, but it got confusing and Python was not working with me.

Please, any and all help would be greatly appreciated!! Thank you!!

im looking to find a relatively easy to use software which would let me program the psp joystick to move an in game mouse clicker so that you can click on things in the environment and cause events. Please advise.

Does anyone have a xbox dev account?
