[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.

Recently, I've made a decision and sold my SuperCard miniSD (which served me quite good for a while) and ordered a brand new, glossy M3 Lite. It's on it's way to me, but I have some questions.

1. Does the M3's filebrowser display hidden folders?
Currently, most of FAT enabled homebrew has it's folders on the root of the media (in this case, the microSD), but on the SuperCard, I simply added the 'hidden' attribute to the folders I didn't want to see and solved the problem. ANSWERED

2. What kind of microSD should I buy?
I'm hanging between Kingston, SanDisk and SanDisk Ultra. Does SanDisk Ultra perform a lot better (I mean - is it worth the extra money)?

3. What do different options in the patching software do?
I especially want to know the meaning of the following:

DMA
Force R/W
Safe Mode
Normal

4. How do I patch a GBA game to use the real-time clock?
I want to play Pokemon Emerald with RTC enabled. However, I couldn't find this option anywhere in the patcher. How do I enable it (I don't need any special effects)?
