This table highlights the variety of approaches available depending on your specific needs. Direct SD card transfer remains the fastest method for bulk transfers, while USB OTG offers convenience for adding games on-the-go. The time estimates assume basic familiarity with file management on a computer. Your actual experience may vary based on library size and computer speed.
Point #1: Direct SD Card Transfer — The Fastest Method
The most reliable way to learn how to load ROMs on R36S starts with direct SD card transfer. Remove your game storage microSD card from the second slot, insert it into your computer using a card reader, and you're ready to go. This method offers maximum transfer speeds and zero connectivity issues.
Your R36S from Lumerk comes with ArkOS pre-installed, which means the folder structure is already prepared. Navigate to the "roms" folder on your SD card—you'll find subfolders for each system like "gba", "snes", "psx", and more. Simply drag your ROM files into the corresponding console folder.

Point #2: Understanding ROM File Formats — Technical Essentials
Not all ROM files are created equal, and knowing which formats work best prevents frustrating compatibility issues. The R36S handles most common formats through its pre-configured ArkOS emulators, but understanding the technical details saves troubleshooting time later.
For Game Boy Advance, stick with .gba files. Super Nintendo works perfectly with .sfc or .smc formats. PlayStation games accept .bin/.cue pairs, .pbp compressed files, or .chd format for optimal storage efficiency. The Mali-G31 MP2 GPU handles these formats effortlessly at 520MHz.
Recommended File Formats by System
- Verify your Game Boy files use .gb or .gbc extensions
- Convert PSX games to .chd format for 60-70% space savings
- Keep BIOS files in the designated bios folder for proper emulation
- Extract compressed .zip files for N64 ROMs—they require uncompressed format
- Rename files without special characters to prevent scanning issues
- Check file integrity if games crash on launch
If you encounter crashes or freezing after loading ROMs, our comprehensive R36S Freezing and Crashing Fix Solutions guide addresses common file-related issues.
Point #3: Folder Structure Organisation — Practical Setup
Proper folder organisation transforms your ROM loading experience from chaotic to seamless. The 1GB DDR3L RAM in your R36S handles game switching efficiently, but a well-organised library makes navigation genuinely enjoyable. Think of folder structure as the foundation of your retro gaming experience.
ArkOS pre-installed on Lumerk consoles creates the essential folder hierarchy automatically. Your primary folders include: roms (game storage), bios (system files), and saves (game progress). Within the roms folder, each console gets its dedicated subfolder following specific naming conventions that ArkOS recognises.
Create subfolders within console directories for genre organisation if desired—"rpg", "action", "puzzle"—though this is optional. The 3.5-inch IPS LCD displays your organised library beautifully with proper thumbnail scraping. Keep folder names lowercase without spaces for maximum compatibility across all emulators.
Point #4: R36S vs Anbernic RG35XX H — ROM Loading Comparison
How does the R36S ROM loading experience compare against the Anbernic RG35XX H? Both devices support microSD storage, but meaningful differences exist. The RG35XX H uses the Allwinner H700 chip, while the R36S packs the Rockchip RK3326 Quad-Core processor running at 1.5GHz.
The Anbernic device runs stock firmware requiring manual GarlicOS or custom firmware installation before optimal ROM organisation. Meanwhile, Lumerk's R36S arrives with ArkOS ready—significantly reducing setup time for how to load ROMs on R36S effectively. The pre-configured emulator cores mean instant compatibility.
Storage flexibility also differs. The R36S provides dual microSD slots supporting 512GB cards each, totalling 1TB potential storage. The RG35XX H offers similar capacity but uses a single TF slot plus internal storage. For detailed performance comparisons, explore our R36S vs Anbernic RG35XX H RetroArch Configuration analysis.
Point #5: USB OTG Transfer — The Hidden Gem Method
Many R36S owners overlook USB OTG transfer capability, yet it's incredibly useful for quick ROM additions without SD card removal. The USB-C port supports OTG functionality, enabling direct connection to flash drives or your computer. This hidden gem method suits spontaneous game library updates perfectly.
Connect a USB-C OTG adapter to your R36S, plug in a flash drive containing your ROMs, and use the built-in file manager to copy games directly. No computer required once your source drive is prepared. The 3000mAh battery provides 3-6 hours of playtime, plenty of power for file transfers.
This method proves especially valuable when friends share game recommendations. Instead of shutting down and removing SD cards, simply connect, transfer, and play. The dual-chip architecture handles these operations smoothly without system slowdowns that plague single-chip devices. To maximise battery during transfers, review our R36S Battery Life Tips.
Point #6: Community Wisdom — What Users Recommend
The retro gaming community has refined ROM loading techniques through extensive experimentation. Seasoned R36S users consistently emphasise several practices that streamline the process. Their collective wisdom saves newcomers considerable frustration when learning how to load ROMs on R36S.
Community members strongly recommend the .chd format for PlayStation games—it compresses disc images significantly while maintaining perfect compatibility. Users report 60-70% storage savings without quality loss. This matters enormously when managing the 512GB microSD capacity across multiple systems.
Another frequently shared tip involves metadata scraping. The SkyScraper tool integrated within ArkOS downloads game artwork, descriptions, and screenshots automatically. Community forums consistently praise this feature for transforming plain file lists into visually stunning game browsers. The 4:3 aspect ratio display showcases these assets beautifully.
Experienced users also warn against purchasing cheap single-chip devices that advertise similar features. The performance difference becomes apparent during actual gameplay. Lumerk's dual-chip design reflects community-tested quality standards.
Point #7: Future-Proofing Your ROM Library — Long-Term Value
Building a ROM library represents time investment worth protecting. Future-proofing your setup ensures years of gaming enjoyment without repeated organisation headaches. The R36S hardware specifications—Rockchip RK3326 processor, Mali-G31 GPU, 1GB RAM—remain capable for its target emulation range.
Standardise your file naming conventions now. Use consistent formats like "Game Name (Region).extension" across your entire library. This practice ensures compatibility with future ArkOS updates and potential firmware improvements. Lumerk's pre-installed ArkOS receives regular community updates, maintaining compatibility with evolving ROM management standards.
Consider maintaining backup copies of your organised library structure. Store a master copy on your computer that mirrors your SD card organisation. When upgrading to larger capacity cards or troubleshooting issues, this backup proves invaluable. The dual microSD slot design actually facilitates testing new organisational approaches on a secondary card without disrupting your primary setup.
