Hacking DS won't turn on

[WIP/Release] ds_mangaman - Turning the Nintendo DS into the Ultimate Vertical Book-Style Manga Reader!

Hwongfish · 2026-06-09T00:33:11+00:00

Hi everyone! I’ve always felt that the Nintendo DS is criminally underrated when it comes to being a dedicated manga-reader. Think about it: it has two screens built right into the form factor, one of them has a precise (not quite most of the time though) touchscreen, and when you rotate the console 90 degrees counter-clockwise, it perfectly mimics the ergonomics of holding a real physical tankobon (manga volume). When held vertically, the D-pad sits perfectly on the bottom, and the shoulder keys (L/R) are in the ideal position for switching chapters. Plus, the touchscreen can be used to magnify for reading the text or inspecting details. Such interactions are the ultimate form factors that modern smartphones just can't match. To prove this, I built ds_mangaman — an open-source, highly optimized homebrew manga viewer for the NDS/NDSL. Download and learn how to build in Github release: :teach::teach::teach: GitHub Repository: https://github.com/hwfish-error408/ds-mangaman :grog::grog::grog: Looking for Contributors! The compiler engine and core state machine are now fully functional and running smoothly on real hardware and emulators (like melonDS). However, I want to take this project further and could really use the community's help! I’m looking for developers, testers, and retro-enthusiasts to help with: A, Implementing a cleaner UI/Main Menu. B, Adding Bookmark support (saving states to SRAM/FAT .sav). C, Further optimizing the DMA memory copy speeds during page and chapter transitions. Feel free to download the source, check out the build pipeline, test it on your flashcarts, and open Issues or Pull Requests on the GitHub repo! Let's make the NDS the ultimate retro manga machine.

Could this be the effects of that ds virus? Was your ds flashed?

Perhaps keep charging it for a while. It will probably boot up again

Actually, I tried it again, its doing the same thing. Red light comes on for a second then goes off.

It's still charging, has been for hours. Has anyone experienced this before?

sounds to me like you might have a duff battery in the DS, I had a similar problem with my first DS lite

Yeah, just try booting it on without the DS Simply in it... If it still has battery problems then just return it to Nintendo.

Why are all the posts edited and gone

Is it that kaos87 found a solution for his DS troubles, and it was such a shamefully, shamefully trivial one, he is afraid to leave his posts here for everyone to see and laugh at his n00bishness?
